Russian scientists have brought the creation of a quantum computer closer

ITMO physicists together with the staff of the London Institute of Mathematical Sciences have found a solution to one of the important tasks for the development of a quantum computer. Modern computers of this type use an increasing number of computational elements — qubits (quantum bits).

The processor has gone: 1000-qubit quantum computers will be mass-produced in Russia

How the discovery of scientists will help create a new generation of computing systems

They serve the same role as bits in classical electronic computers. Some devices have more than a thousand of them, so data transfer between them becomes a problem. Russian experts have found a way to transmit information encoded in quantum states as fast as possible.

"The importance of this work is not so much in solving a specific problem about state transfer in an array of qubits, but rather in developing a new method suitable for large quantum systems. This will allow us to find more efficient quantum algorithms, prepare quantum states faster, and generally expand the capabilities of modern quantum systems," said Maxim Gorlach, a leading researcher at ITMO.

The processors of many quantum computers already consist of many qubits. And their number will only grow. Google intends to reach 1,000 units of information in the near future, and IBM has already created the Condor machine, which includes 1,121 qubits.
