Microsoft Says It Has Created a New State of Matter to Power Quantum Computers
Anyone who has sat through a third-grade science class knows there are three primary states of matter: solid, liquid and gas.
Microsoft now says it has created a new state of matter in its quest to make a powerful machine, called a quantum computer, that could accelerate the development of everything from batteries to medicines to artificial intelligence.
On Wednesday, Microsoft’s scientists said they had built what is known as a “topological qubit” based on this new phase of physical existence, which could be harnessed to solve mathematical, scientific and technological problems.
With the development, Microsoft is raising the stakes in what is set to be the next big technological contest, beyond today’s race over artificial intelligence. Scientists have chased the dream of a quantum computer — a machine that could exploit the strange and exceedingly powerful behavior of subatomic particles or very cold objects — since the 1980s.
The push heated up in December when Google unveiled an experimental quantum computer that needed just five minutes to complete a calculation that most supercomputers could not finish in 10 septillion years — longer than the age of the known universe.
Microsoft’s quantum technology could leapfrog the methods under development at Google. As part of its research, the company built multiple topological qubits inside a new kind of computer chip that combines the strengths of the semiconductors that power classical computers with the superconductors that are typically used to build a quantum computer.
When such a chip is cooled to extremely low temperatures, it behaves in unusual and powerful ways that Microsoft believes will allow it to solve technological, mathematical and scientific problems that classical machines never could. The technology is not as volatile as other quantum technologies, the company said, making it easier to exploit its power.
Some question whether Microsoft has achieved this milestone, and many leading academics said quantum computers would not be fully realized for decades. But Microsoft’s scientists said their methods would help them reach the finish line sooner.
“We view this as something that is years away, not decades away,” said Chetan Nayak, a Microsoft technical fellow who led the team that built the technology.
Microsoft’s technology, which was detailed in a research paper published in the science journal Nature on Wednesday, adds new impetus to a race that could reshape the technological landscape. In addition to accelerating progress across many technological and scientific fields, a quantum computer could be powerful enough to break the encryption that protects national secrets.
Any advances are set to have geopolitical implications. Even as the United States explores quantum computing primarily through corporations like Microsoft and a wave of start-ups, the Chinese government has said it is investing $15.2 billion in the technology. The European Union has committed $7.2 billion.
Quantum computing, which builds on decades of research into a type of physics called quantum mechanics, is still an experimental technology. But after recent strides by Microsoft, Google and others, scientists are confident that the technology will eventually live up to its promise.
“Quantum computing is a thrilling prospect for physics, and for the world,” said Frank Wilczek, a theoretical physicist at the Massachusetts Institute of Technology.
To understand quantum computing, it helps to know how a traditional computer works. A smartphone, laptop or desktop PC relies on tiny chips made from semiconductors, which are materials that conduct electricity in some but not all situations. These chips store and process numbers, adding them, multiplying them and so on. They perform these calculations by manipulating “bits” of information. Each bit holds either a 1 or a 0.
A quantum computer operates differently. A quantum bit, or qubit, relies on the curious behavior of subatomic particles or exotic materials cooled to extremely low temperatures.
When it is either extremely small or extremely cold, a single object can behave like two separate objects at the same time. By harnessing that behavior, scientists can build a qubit that holds a combination of 1 and 0. This means that two qubits can hold four values at once. And as the number of qubits grows, a quantum computer becomes exponentially more powerful.
Companies use a variety of techniques to build these machines. In the United States, most, including Google, build qubits using superconductors, which are materials that conduct electricity without losing the energy they are transmitting. They create these superconductors by cooling metals to extremely low temperatures.
Microsoft has bet on an approach that few others are taking: combining semiconductors with superconductors. The basic principle — along with the name topological qubit — was first proposed in 1997 by Alexei Kitaev, a Russian American physicist.
The company began working on this unusual project in the early 2000s, when many researchers did not think such technology was possible. It is Microsoft’s longest-running research project.
“This is something that all three C.E.O.s of this company have bet on,” Satya Nadella, Microsoft’s chief executive, said in an interview. (The company’s previous C.E.O.s were Bill Gates, a founder, and Steve Ballmer, who ran Microsoft in the early 2000s.)
The company has now created a single device that is part indium arsenide (a type of semiconductor) and part aluminum (a superconductor at low temperatures). When it is cooled to about 400 degrees below zero, it exhibits a kind of otherworldly behavior that might make quantum computers possible.
Philip Kim, a physics professor at Harvard, said Microsoft’s new creation was significant because topological qubits could accelerate the development of quantum computers. “If everything works out, Microsoft’s research could be revolutionary,” he said.
But Jason Alicea, a professor of theoretical physics at the California Institute of Technology, questioned whether the company had actually built a topological qubit, saying the behavior of quantum systems is often hard to prove.
“A topological qubit is possible in principle, and people agree it is a worthwhile goal,” Dr. Alicea said. “You have to verify, though, that a device behaves in all the magical ways that theory predicts it should; otherwise, the reality may turn out to be less rosy for quantum computing. Fortunately, Microsoft is now set up to try.”
Microsoft said that it had built only eight topological qubits, and that they were not yet able to perform calculations that would change the nature of computing. But the company’s researchers see this as a step toward building something far more powerful.
For now, the technology still makes too many errors to be truly useful, though scientists are developing ways to reduce mistakes.
Last year, Google showed that as it increased the number of qubits, it could exponentially reduce the number of errors through complex mathematical techniques.
Error correction will be less complex and more efficient if Microsoft can perfect its topological qubits, many scientists said.
While a qubit can hold multiple values at the same time, it is burdened by an inherent problem. When researchers try to read the information stored in a qubit, it “decoheres” and collapses into a classical bit that holds only one value: a 1 or a 0.
This means that if someone tries reading a qubit, it loses its basic power. So scientists need to overcome an essential problem: How do you build a computer if it breaks whenever you use it?
Google’s error correction methods are a way of dealing with this issue. Microsoft believes it can solve the problem faster because topological qubits behave differently and are theoretically less likely to collapse when someone reads the information they store.
“It makes for a really good qubit,” Dr. Nayak said.

President Trump has signed off on a plan to fire Dr. Marty Makary, commissioner of the Food and Drug Administration, after a series of clashes over vaping, oversight of the abortion pill and a series of new drug application denials that rattled biotech companies, according to a person briefed on the matter, who was not authorized to discuss it publicly.
Dr. Makary had a high profile for an F.D.A. commissioner, appearing frequently on television and podcasts to sell the work he was doing at the agency on improving the food supply, speeding up some drug approvals and trying to restore agency morale after thousands of staff members left.
He tried to walk the tightrope between the business-friendly Make America Great Again movement, pledging to get rid of regulations that slow down innovation and to attract more drug trials to the United States. He was an ally of Health Secretary Robert F. Kennedy Jr.’s Make American Healthy Again supporters, voicing the skepticism of the pharmaceutical industry and authorizing natural food dyes.
Ultimately, Dr. Makary’s efforts were not enough to overcome the grievances of a growing band of enemies focused on selling tobacco, opposing abortion and seeing biotech therapies authorized.
Mr. Trump’s decision to dismiss him was first reported by The Wall Street Journal.
The decision could still change, given Mr. Trump’s propensity to change his mind Dr. Makary has also proven persuasive with Mr. Trump in beating back previous efforts to oust him.
Leaving the White House Friday evening, Mr. Trump dismissed the idea that Dr. Makary would be fired.
“I’ve been reading about it, but I know nothing about it,” he said.
The White House has pressured Dr. Makary for months to authorize flavored e-cigarettes, according to a person close to the conversations. The approvals were a top wish of major tobacco companies that have been top donors to Mr. Trump. In March, the F.D.A. issued a memo saying that it would only authorize e-cigarettes in flavors such as mint, tea and spices. The memo said the fruit and candy flavors would be unlikely to pass muster, given their appeal to young people.
Pressure continued, though, and on Tuesday the F.D.A. authorized blueberry and mango flavored e-cigarettes by Glas, a small company based in Los Angeles.
Abortion foes including Susan B. Anthony Pro-Life America have continued to turn up the heat on Dr. Makary, reiterating their call for his firing on Thursday. The group’s leaders and others view Dr. Makary as dragging his feet on a safety review of the abortion pill mifepristone, which they viewed as a way to highlight what they believe are dangers of the drug. Former Vice President Mike Pence, who also opposes abortion rights, amplified criticism of Dr. Makary on social media as well.
The administration has been under pressure from conservatives to tighten regulations on the prescribing and dispensing of mifepristone. The Supreme Court is reviewing a federal appeals court ruling that temporarily blocked abortion providers from prescribing the drug through telemedicine and sending it to patients by mail.
Biotech companies and their investors have also raised alarms with the White House about agency decisions to reject a series of treatments for rare diseases. The F.D.A. typically turns down about 20 percent of the applications it receives for drug approvals from companies.
Dr. Makary has been aggressive in defending the decisions, which he said came from career scientists who found the medications ineffective.
Dr. Makary also had to contend with a health secretary who seemed to view the F.D.A. as an avenue for getting his favored products authorized, exemplified by Mr. Kennedy’s social media post saying that the agency would end its “war on” stem cell treatments, peptides and raw milk. Mr. Kennedy pushed the F.D.A. to reverse a 2023 ban and allow the use of a number of peptides, unproven compounds purported to offer anti-aging or muscle-recovery benefits.
Before leading the F.D.A., Dr. Makary was a cancer surgeon and health policy researcher at Johns Hopkins University School of Medicine. He was also the author of several books about the health care system.
Some of Dr. Makary’s more popular moves included encouraging broader use of hormone replacement products for women and lifting the F.D.A.’s warnings on them. He helped speed some promising drugs to market, including a pancreatic cancer therapy and the pill form of the popular GLP-1 weight loss drugs.
Some California residents were among the 147 passengers and staff aboard a luxury cruise ship stricken by a suspected outbreak of hantavirus that has left three people dead and several others severely ill, officials confirmed Thursday.
California public health officials say they are monitoring the situation after being notified by the U.S. Centers for Disease Control and Prevention that some state residents were passengers on the MV Hondius. The precise status of those individuals, however, remains murky.
Hantavirus is a rare but deadly disease that attacks the lungs and is typically contracted by humans through inhalation of particles contaminated with the urine, feces or saliva of a wild rodent.
However, Dr. Tedros Adhanom Ghebreyesus, director-general of the World Health Organization, confirmed Thursday that the Andes virus — a form of hantavirus that can spread from person to person — was involved in the outbreak.
Here’s what we know:

As its name suggests, the Andes virus is typically found in South America. The Dutch-flagged MV Hondius was on a 46-day journey that traveled from Antarctica with stops in Argentina.
In the case of human-to-human transmission, a person would first be infected by a wild rodent’s contaminated particles and then pass the infection to someone else, said Dr. Gaby Frank, director of the Johns Hopkins Special Pathogens Center.
“In previous outbreaks of Andes virus, transmission between people has been associated with close and prolonged contact, particularly among household members, intimate partners and people providing medical care,” Ghebreyesus said. “That appears to be the case in the current situation.”
None of the remaining passengers or crew members on the ship are symptomatic, he said.
The ship was not permitted to allow passengers to disembark at its original destination, Cape Verde, and is sailing for Spain’s Canary Islands.
“I want to be unequivocal here: This is not SARS-CoV-2. This is not the start of a COVID pandemic. This is an outbreak that we see on a ship. There’s a confined area,” Dr. Maria Van Kerkhove, who leads the WHO’s epidemic and pandemic management, said at a briefing. “This is not the same situation we were in six years ago. It doesn’t spread the same way like coronaviruses do.”
California passengers on the cruise
On April 1, 114 guests boarded the cruise ship in Ushuaia, Argentina. Twenty-three days later, 30 passengers — including six people from the United States — disembarked on a stop in St. Helena, a remote island about 1,100 miles off the coast of Africa, according to the cruise operator Oceanwide Expeditions.
Public health agencies in California, Georgia and Arizona were notified by the CDC that some of their residents were among the passengers on the cruise. It’s unclear whether these individuals disembarked on April 24, however.
The CDC is assisting local health authorities with monitoring California residents who were aboard the cruise, according to a statement by the California Department of Public Health on Friday.
As of Friday, one passenger has returned to their California residence and is in contact with local public health officials, and at least one other remains aboard the ship, according to the state agency.
“We understand that news of an unusual outbreak can be concerning,” said Dr. Erica Pan, director of the California Department of Public Health. “Unlike influenza and COVID-19, years of experience in South America have shown that this Andes hantavirus rarely spreads between people.”
Officials said the current public health protocol is to do daily symptom monitoring and reporting.
“As there are no known cases of Andes hantavirus infection from people without symptoms, and any spread has usually been limited to people with prolonged close contact with an ill person with this virus, the risk to the general public in California is extremely low,” the agency said in a statement.
In a statement earlier this week, the CDC also said that the risk to the American public “is extremely low” at this time.
“We urge all Americans aboard the ship to follow the guidance of health officials as we work to bring you home safely,” the agency said.
The others who exited the ship on April 24 were individuals from Canada, Denmark, Germany, the Netherlands, New Zealand, Switzerland, Sweden, Singapore, St. Kitts and Nevis, Turkey and the United Kingdom.
Of the remaining passengers still aboard the ship headed for Spain’s Canary Islands, California Department of Public Health said none were ill as of Friday.
How many people have been infected?
The number of lab-confirmed hantavirus cases has risen to five, according to the WHO. There are three additional suspected cases.
A timeline of reported cases of hantavirus aboard the cruise ship can be found here.
The WHO is monitoring reports of other people with symptoms “who may have had contact with one of the passengers. In each case, we are in close contact with the relevant authorities,” Tedros said.
The first passenger to have been infected, a Dutchman, became sick aboard the cruise ship on April 6 and died on April 11.
No samples were taken, because his symptoms were similar to other respiratory diseases. His widow left the ship with his body on April 24 during the scheduled stop at St. Helena.
“She deteriorated during a flight to Johannesburg on the 25th of April and died the next day,” Tedros said.
Before boarding the cruise ship, the Dutch couple had traveled through Argentina, Chile and Uruguay on a bird-watching trip, “which included visits to sites where the species of rat that is known to carry Andes virus was present,” Tedros said.
After leaving the ship, the woman was briefly aboard a KLM aircraft in Johannesburg bound for Amsterdam but was barred from the flight due to her medical condition, the airline said in a statement.
Dutch news outlets reported that a flight attendant on a KLM airplane — who briefly had contact with the widow — started feeling sick and had mild symptoms and was in isolation at a hospital in Amsterdam.
The flight attendant has since tested negative for the Andes virus, Dr. Jeremy Faust, an emergency medicine physician, wrote on his Substack blog, Inside Medicine, citing a text message sent to him by Tedros.
“It is still possible that the flight attendant contracted the Andes virus. However, given our understanding of the virus, this information means that the flight attendant’s symptoms are not caused by the Andes hantavirus, but by some other medical illness,” Faust wrote.
More cases may be reported, because the incubation period — the time it takes between exposure to the virus and the onset of illness — for the Andes strain of the hantavirus is up to six weeks.
What we know about hantavirus
There are roughly 50 identified species of hantavirus. The virus that’s found in the Americas tends to cause a cardiopulmonary syndrome, a condition that affects the heart and the lungs, according to Frank.
There have been 890 laboratory-confirmed cases of hantavirus disease reported in the U.S. since surveillance began in 1993, according to the most recent data from the CDC.
From 1980 to 2025, 99 California residents have been diagnosed with a hantavirus infection, according to the California Department of Public Health.
CDC officials said 38% of people who develop respiratory symptoms may die from the disease.
Still, the data suggest that contracting hantavirus is rare, said Dr. Afif El-Hasan, member of the American Lung Assn.’s national board of directors.
There is no vaccine or specific antiviral medicine for hantavirius.
Intensive-care treatment may include intubation and oxygen therapy, fluid replacement and use of medications to lower blood pressure, according to the American Lung Assn.
The signs of hantavirus
Early symptoms of hantavirus are similar to the flu and include fatigue, fever and muscle aches, according to the CDC. Symptoms start to develop within one to eight weeks after contact with an infected rodent.
Half of those who contract the virus also experience headaches, dizziness, chills, nausea, vomiting, diarrhea and abdominal pain.
Four to 10 days after the initial phase of the illness, another round of symptoms can develop, which include coughing, shortness of breath and possible tightness in the chest as the lungs fill with fluid.
Even though contracting hantavirus in the U.S. continues to be a rare event, El-Hasan said, people should take these initial symptoms seriously and promptly seek medical care.
How to protect yourself
Hantavirus cases can occur year-round, but the peak seasons in the United States are the spring and summer, which coincide with the reproductive seasons for deer mice.
To lessen your risk of infection, keep wild rodents out of your home and other enclosed spaces by sealing any holes and placing snap traps.
If you find evidence of mice, wear personal protective equipment and disinfect the area. When you’re done, put everything, including cleaning materials, in a bag and toss it in your trash bin.
