The new Bristlecone processor from Google was presented at the annual meeting of the American Physical Society, which takes place in Los Angeles.
What distinguishes the Google quantum processor from the previously presented IBM, Intel and Microsoft chips? The company boasts that its unit equipped with 72-qits is characterized by a much lower level of errors than previous designs (it is the huge number of errors generated by these systems that is currently one of the problems that are not yet widely used). Interestingly, for such a system to work properly, it should be cooled to a temperature of 0.01 Kelvin – only then is it able to avoid the penetration of electrical and magnetic noise, which effectively interfere with the calculation.
The Bristlecone system is just the beginning of Google’s work on a quantum unit that will beat the systems we have known so far. Google is on track to overcome competition in a quantum fight. In a nutshell, the more qubits will have the produced system, the better it will be able to cope with the tasks assigned to it – including carrying out incredibly complicated simulations.
