Microsoft said he was able to use a new state of matter to create basic building blocks of quantum computer, limiting a 20-year struggle at the boundaries of physics that many in the quantum world have rejected as unspeakable.
American Technological Diva said he believed that development would allow you to build practically quantum The computer by the end of the decade and eventually skip others on the field.
The claim adds a new turn in the race to create a new form of advanced calculation that has withdrawn in some of the largest American technological companies and became central to the fight for technological leadership between the USA -ai China.
Microsoft’s hard breakthrough follows years of research on a type of particle containing the fourth state of matter, different from solids, liquids and gases. The existence of particles, known as the Mayan Fermions, was first theorized in 1937, although scientists struggled to show that they actually exist.
Microsoft The head of Satya Nadella said eight years ago that her work on technology was “at the height of the” “quantum revolution”. But only in 2022, the company scientists could even record the effects they believed were caused by particles.
The American Technology Group put a bet on the theoretical particles after deciding to offer the best path to overcoming the biggest obstacle to the construction of a practical quantum machine. While the bits in the traditional computer represent One or zero, the Qubits used in quantum computers may also represent at once or any condition between.
However, most of the Qubita species hold only their quantum states for small seconds, which means that any information they hold are lost quickly. To make up for this, a fully functioning quantum computer will require many additional quibit to start the software required to correct the errors.
For comparison, the so -called topology quits Microsoft tried to make the use of the magazine particles more resistant to errors. The information is held throughout Qubit, which means that even when the parts fail, the topological quit as a whole should retain enough information to be useful, said Sankar Das Sarma, a physics professor at Maryland University.
This higher stability means that Microsoft is likely to only need about 100 additional quit to correct mistakes for each, completely operating quit, said Jason Zander, Executive Vice President of Strategic Mission and Technology in Microsoft. This is about tenths as much as it is expected to be required in machines whose quits are based on other materials.
The latest information published by Microsoft, including the work published in nature on Wednesday, represented a significant breakthrough according to creating feasible topology quits, Das Sarma said. However, he said there is still a small chance that the findings of companies can explain something other than successful exploitation of elusive particles.
Microsoft’s long -lasting research effort was tortured by problems that make components capable of producing and controlling particles. In 2018, the company published a joint survey with numerous universities claiming that they were watching particles but later pulled the paper After recognizing inconsistencies in the data.
Speaking before the latest announcements, a longtime Quantum Computing investor compared his ambitious research with the search for cold fusion, efforts to create a nuclear reaction at a room temperature that became a word for scientific extension.
It also comes only a few weeks after the NVIDIA -Ensen Huang director forecast that the useful quantum computers are still 20 years – much longer than the companies working on the ground.
In one sign of official interest in ambitious technology, Darpa, the US Defense Service Agency in charge of developing advanced technologies, selected Microsoft this month to try to show that it could build a large quantum computer.
The American start-up psiquantum, the only other company chosen by Darpa, uses Qubits based on photons, and last year announced a $ 620 million project to build a quantum system entirely in Australia.
With the latest research and data that support their claims that they have mastered the major particles, Microsoft said he built the first processor using technology.
Called Majoram 1, the chip is based on eight topological quit. The small size of each component meant that she would eventually be able to squeeze up to 1 Mn Qubits on each chip, creating a quantum computer to a full extent, the company said.
