Quantum circuits computing unitary transformations

Year: 2021
Type: preprint
Abstract: Let $H_1, H_2$ be Hilbert spaces of the same finite dimension $\ge2$, and $C$ an arbitrary quantum circuit with (principal) input state in $H_1$ and (principal) output state in $H_2$. $C$ may use ancillas and produce garbage which is traced out. $C$ may employ classical channels and measurement gates. If $C$ computes, for each computation path $\mu$ through the circuit, a unitary transformation $U_\mu: H_1 \to H_2$ then, for each $\mu$, the probability that a computation takes path $\mu$ is independent of the input.
