gate_bit_flip: Bit flip

In henry090/Cirq: Interface to 'Cirq'

Description

with probability of a flip given by p. If p is NULL, return a guaranteed flip in the form of an X operation. This channel evolves a density matrix via $$ \rho \rightarrow M_0 \rho M_0^\dagger + M_1 \rho M_1^\dagger $$ With $$ \beginaligned M_0 =& \sqrtp \beginbmatrix 1 & 0 \ 0 & 1 \endbmatrix \ M_1 =& \sqrt1-p \beginbmatrix 0 & 1 \ 1 & -0 \endbmatrix \endaligned $$

Usage

gate_bit_flip(p = NULL)

Arguments

p	the probability of a bit flip.

Value

Construct a BitFlipChannel that flips a qubit state.

Raises

ValueError: if p is not a valid probability.
