There is always noise in the microworld. Even in absolute emptiness, something trembles, and these quantum fluctuations interfere with precise measurements. But noise can be "squeezed," like a balloon: if you squeeze it from the sides, one part gets thinner while the other bulges.

Tuning a quantum processor is monotonous work: you need to calibrate each qubit — a quantum cell — much like a watchmaker adjusting dozens of tiny gears. Humans get tired and make mistakes.
