A quantum computer is like an orchestra where each musician plays their own part. If the conductor slips up, the music falls apart. In digital quantum simulations, the conductor's role is played by a sequence of simple operations, and errors accumulate like wrong notes.

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.
