Microsoft claims quantum breakthrough after 20-year pursuit of elusive particle

Digest opened free editor

Microsoft said it had succeeded in harnessing a new case of the material to create the basic blocks of the quantum computer, crowning a 20 -year struggle on the boundaries of physics that many in the world of quantum rejected as impractical.

A giant of American technology said it believes that development will enable it to build a process Quantity The computer by the end of the contract and finally jumped in the others in this field.

The claim adds a new development to the race to create a new form of advanced computing that has been drawn in some of the largest American technology companies and becomes essential to struggle for technical leadership between the United States and China.

The backed microsoft penetration follows years of research in a type of particle that includes a fourth case of the material, distinct from solid materials, fluids and gases. The presence of particles, known as Majerana Fermions, was postponed first in 1937, although scientists have struggled to prove their existence already.

Microsoft Leader Satia Nadella said eight years ago that her work on technology put her “on the threshold” “quantum revolution.” But until 2022, it was not that the company’s scientists were able to record the effects that they believed were caused by particles.

The American Technology Group has placed its bet on theoretical particles after it decided that it had presented the best way to overcome the largest obstacle to building a practical amount of quantity. While the bits in a traditional computer represent those or zeros, the Qubits used in quantum computers is able to represent both once, or any case between them.

However, most of the Qubit species only carry their quantum states of small fractures of a second, which means that any information they carry has been lost quickly. To compensate for this, computers that operate at full capacity will require many additional Qubits to run the program to correct errors.

In comparison, what is called Qubits that Microsoft is trying to make the use of majoraana molecules more wrongly resistant. Sancar Das Sarma, Professor of Physics at the University of Maryland, said that the information is kept via the entire Qubit, which means that even when the parts fail, the Qubit Tobiti as a whole must keep sufficient topics to make them useful.

This greater stability means that Microsoft is likely to need an additional 100 Qubits to completely correct errors for each one of Qubit. This is almost the tenth as expected to be required in machines that Qubits depends on other materials.

Das Sarma said that the latest data issued by Microsoft, including in a paper published in Nature on Wednesday, represented a major breakthrough towards the creation of practical Tobits. However, he said that there is still a small opportunity to remove the company’s results by something other than harnessing the dodging particles.

Microsoft’s long -term research efforts have been afflicted with problems in making the ingredients able to produce and control particles. The company published a joint research with a number of universities in 2018, claiming that it had noticed the particles but later Retreat After admitting the contradictions in the data.

Speaking before the last announcement, one of the investors has long compared the quantum computing his ambitious research to the pursuit of cold fusion, which is the efforts made to produce a nuclear reaction at room temperature, which has become a nutritional word for excessive scientific occurrence.

It also comes only weeks after the CEO of Nvidia Jensen Huang expects that useful quantum computers still still 20 years old – Many longer companies operating in this field.

In a signs of official interest in the United States in ambitious technology, DARPA, the US Defense Ministry Agency in charge of developing advanced technologies, Microsoft has chosen this month to try to prove that it could build a large -scale quantitative computers.

Psiquantum in the United States uses the only company chosen by DarPa, Qubits based on photons, and last year it announced a $ 620 million project to build a large -scale quantum system in Australia.

Along with the latest research and data that supports its allegations that they mastered the majoraana particles, Microsoft said it built the first processor using technology.

It is called majoraana 1, and the slide is based on the eight Qubits Tobits. The company said that the small size of each component means that it will eventually be able to press up to 1 million quarterly on each slide, creating a large quantitative computer.
