In a standard computer, a controller sends simple "on/off" signals. In a quantum computer, the controller sends that gently nudge a qubit (a particle that is both 0 and 1 simultaneously). The controller must be incredibly fast, incredibly cold, and incredibly precise. If it is 1% off, the quantum state collapses into noise.
Imagine trying to conduct an orchestra where the musicians exist in two places at once and the music only plays for a millionth of a second. That is a quantum controller. quantum controller
Today, building a better quantum controller is as important as building more qubits. Without the conductor, the orchestra is just noise. (Reply with Track 1 , 2 , or 3 ). In a standard computer, a controller sends simple
