American Google has created the world's most powerful quantum computer, capable of performing orders of magnitude faster computations than IBM's Summit, considered the world's most powerful supercomputer, according to the Financial Times.
The British newspaper writes that the calculation, on which the device from IBM took 10 thousand years, made a computer from Google in 200 seconds, and this information, first published in a scientific report on the NASA website, was subsequently deleted. It is noted that at present, a quantum computer from Google is able to perform only one technical calculation, and the device will be ready to solve practical problems in a few years.
“As far as we know, the conducted experiment represents the first calculation that can only be performed on a quantum processor,” the publication quotes the material. It also says that "such a serious acceleration compared with the well-known classical algorithms provides an experimental implementation of quantum superiority in the computational problem."
The newspaper writes that Google developers called their computer “an important milestone on the road to a full-scale quantum computing process,” and predicted that the increase in the power of quantum computers would be several times greater than the progression figures in Gordon Moore’s law.
The Financial Times indicates that Google declined to comment.
In November 2017, the head of IBM's quantum computer department, Dario Gil, announced that the developers had created a working prototype of a computer with a capacity of 50 qubits (quantum bits).
In a classical computer, information is represented using bits that take only the values 0 or 1. In a quantum computer, the concept of a (classical) bit is generalized to a quantum bit (qubit) that takes an infinite number of values, each of which is a quantum superposition of the basis states 0 and 1 (pair values of the quantum characteristics of a particle, for example, an atom, electron or photon, in particular, spin orientation). Physical carriers in such a device are, for example, special superconducting solid-state materials in which particles can be brought into a special excited (quantum) state, identified as a qubit state. Such material (and quantum states) can be controlled, for example, by a laser.
