Google began to create a 50-qubit quantum computer

Now more and more companies are trying their hand at the field of creation of quantum computers. So Google decided to join this race and announced that the company's researchers are engaged in the development of quantum computing technology. Google already has a working sample of a six-kilobit quantum processor, but now experts are focused on creating a computer with 50 qubits. The most powerful in the world at the moment.

John Martinis is at the head of the research team responsible for the development, and they plan to create their own quantum device by the end of this year. If successful, Google will be the first to cross the so-called "quantum excellence barrier". This is the barrier after which the performance of the quantum system during the execution of specialized tasks will be far beyond the capabilities of any of the existing supercomputers.

The already existing six-qubit quantum chip at Google has become a testing ground for the development of technologies for making qubits, as well as the organization of connections between them. The development of technologies for creating a computer took about two years. According to John Martínis,

"We still have to do some work, in particular in the area of ​​the qubits location, as they will be located on chips of large-scale quantum systems. But all the processes developed by us are working properly, and we are ready to make a sharp qualitative leap. This jump will be the creation of systems with 30-50 qubits, work on which is already underway. "

Test Google Chip

Now the research group has 25 people, and at the moment it conducts final tests of some design features of the future quantum computing system. For example, the linear arrangement of the qubit chains is tested, from which a two-dimensional matrix for the computer will be assembled. It should be said that if the search giant succeeds, their processor will be a huge step towards the emergence of real universal quantum computers.
