Quantum machine learning

Quantum computation,

Interference is the main difference between quantum theory and classical probability theory.

Decoherence. Kinda: phases are instable, and so the interference terms usually average out to zero. Quantum error-correction is a way to fight this problem.

Hadamard gate 1 1 1 -1

Phase gate 1 0 0 $e^{i\phi}$
