cirq.generalized_amplitude_damp

Returns a GeneralizedAmplitudeDampingChannel with probabilities gamma and p.

Used in the notebooks

Used in the tutorials

This channel evolves a density matrix via:

$$ \rho \rightarrow M_0 \rho M_0^\dagger + M_1 \rho M_1^\dagger

  + M_2 \rho M_2^\dagger + M_3 \rho M_3^\dagger

$$

With:

M0=p[1001γ]M1=p[0γ00]M2=1p[1γ001]M3=1p[00γ0]

gamma the probability of the interaction being dissipative.
p the probability of the qubit and environment exchanging energy.

ValueError gamma or p is not a valid probability.
