Returns an AmplitudeDampingChannel with the given probability gamma.
cirq.amplitude_damp(
gamma: float
) -> cirq.AmplitudeDampingChannel
Used in the notebooks
This channel evolves a density matrix via:
$$
\rho \rightarrow M_0 \rho M_0^\dagger + M_1 \rho M_1^\dagger
$$
With:
\[
\begin{aligned}
M_0 =& \begin{bmatrix}
1 & 0 \\
0 & \sqrt{1 - \gamma}
\end{bmatrix}
\\
M_1 =& \begin{bmatrix}
0 & \sqrt{\gamma} \\
0 & 0
\end{bmatrix}
\end{aligned}
\]
Args |
