In June this year, the American concern IBM placed a quantum computer in Germany.
It is the most powerful commercial quantum computer in Europe – 27 qubits. To understand the operation of such a computer should refer to the principle of traditional operation.
A classic computer stores information as a sequence of zeros and ones. Whether it’s a computer game, photo viewing, or cryptographic calculations, it’s all done in binary, where 0 or 1 and nothing else. The inefficiency of such a system is manifested when 0 and 1 become too much and there are not enough resources to store and calculate them.
A qubit is the smallest indivisible particle of quantum information. It is he who solves this problem. This piece of information uses the properties of quantum physics that allow it to remain in superposition. The qubit can take any value from 0 to 1. It has the properties of the whole spectrum and can have values, for example, 15 percent zero and 85 percent one.
We will find out in the future how powerful a computer launched in Germany will be. For comparison, Google in September 2019 already announced the creation of its 54-cubic-meter processor. In 3 minutes and 20 seconds, he was able to calculate what IBM’s most powerful computer at the time would have spent 10,000 years on.
