In Russia, they tested a quantum computer on superconductors

A prototype of the first domestic quantum computer was launched in Russia. This was reported on the eve by the representatives (NITU) of MISiS. The configuration of the device includes 2 qubits made on the basis of superconductors.




As the first task for the brainchild of Russian engineers, a solution to the Grover algorithm (enumeration method) was chosen. Ideally, a powerful quantum computer can solve the problem with a probability of 100% in one call to the function f (x). However, due to the fact that the apparatus developed by scientists from (NUST) MISiS has a small number of q-bits, the probability of obtaining the right solution was 53%. Which, in general, exceeds the average threshold.

Creating a processor for the first domestic quantum computer involved in the Moscow State Technical University. Bauman project NITU "MISiS." For the efficient operation of the CPU, a unique complex was created on the basis of the university. The latter, thanks to equipment with cryostats, ensures the operation of the system at a temperature equal to absolute zero (-273,14 ° C).

Despite the fact that the prototype of the Russian quantum computer has a 2-qubit configuration, it compares favorably with foreign counterparts. The thing is that domestic q-bits based on superconductors cannot be "lost" and can be built nonlinearly. What can’t “boast” of qubits on individual atoms or ions. In addition, aluminum q-bits created by domestic engineers are better suited for quantum error correction.

    Like in a joke: the program works, but shows incorrect results)))

    Slowly, little by little, domestic science is moving forward. Well done.

    Cool, cool! Finally, after the iPhone killers and aircraft carrier killers, we got an IBM killer with its 53 qubits !!!

    - Personally, I didn’t understand anything ... - what is it at all .. ???

    - Ha ... ha ...

    - Yes, of course ... - the “fewer qubits”, the less you can lose them ...

    -Hahah ... Yes, and yet ... why ask "stupid questions" ... - they say that it’s harder ... a kilogram of gold or a kilogram of swan fluff ... -There, even any site minuser understands that, of course. .. - a kilogram of gold is heavier. - So our "two qubits" will outweigh everyone ... - so be it ... - Hahah ...
