Quantum computing accumulation of knowledge

Reversible computation

Fredkin gate

input ports (a, b, c) Two input ports are used for the operand data (a, b), the third port being used
for a control bit c.

Toffoli gates

ab 1 c are inverted,
such as AND OR truth table and the like, a plurality of values corresponding to the number, it can not correspond, but both of the above are a gate input corresponding to an output, it is reversible computing.

Getting quantum field of machine learning, maybe we can start reading from the Phase Estimation algorithm:
