gate_phase_flip: Phase flip

In henry090/Cirq: Interface to 'Cirq'

Description

if p is NULL, return a guaranteed phase flip in the form of a Z operation. This channel evolves a density matrix via: $$ \rho \rightarrow M_0 \rho M_0^\dagger + M_1 \rho M_1^\dagger $$ With: $$ \beginaligned M_0 =& \sqrtp \beginbmatrix 1 & 0 \ 0 & 1 \endbmatrix \ M_1 =& \sqrt1-p \beginbmatrix 1 & 0 \ 0 & -1 \endbmatrix \endaligned $$

Usage

gate_phase_flip(p = NULL)

Arguments

p	the probability of a phase flip.

Value

a phase flip channel that flips a qubit's phase with probability p

Raises

ValueError: if p is not a valid probability.
