On the creation of a prototype 50-qubit quantum computer IBM reported in early November 2017. It is located in the laboratory of IBM Q and is enclosed in a large cylindrical body in white color, to which the cooling system pumps and a number of traditional PCs for performing various tasks and algorithms are brought.
Thanks to a series of high-quality photos, you can see in detail the 50-kbit quantum computer of the blue giant.
From a distance it looks like a steampunk chandelier, but in fact this "chandelier" is one of the most complex quantum computers ever created.
Failure to comply with the desired temperature in the room makes the machine completely useless. It is here that the cooling system with liquid helium enters the game. The system is divided into four main parts and each level has its own temperature - for the uppermost part it is -269.15 ° C, for medium -272.35 ° C and -273.05 ° C respectively
, and for the lowest one -273.14 ° C. Inside the tank, the temperature is close to absolute zero.
By connections, RF signals are fed into the processor. Then they are converted into qubits to execute a particular program. The wires are connected in such a way as to prevent the influence of extraneous noise, including heat, on the quantum processor. storage under.
In September last year, in one of the experiments, IBM scientists were able to recreate beryllium hydride (BeH2) on a seven-bit quantum processor. But skeptics need something more substantial, something more important for the average consumer.
Welser noted that somewhere between 50 and 100 qubits, the advantages of quantum systems will become more evident. In other words, to quantum superiority -
not for long.
