create_amplitude_damping_channel_operator#

cuquantum.bindings.cupauliprop.create_amplitude_damping_channel_operator( intptr_t handle, int32_t qubit_ind_ex, double damping_prob, double excite_prob, ) → intptr_t[source]#

Creates a generalised amplitude damping channel.

Parameters:

handle (intptr_t) – Library handle.
qubit_ind_ex (int32_t) – Index of qubit upon which to operate.
damping_prob (double) – Probability that the qubit is damped, i.e. decohered into a classical state.
excite_prob (double) – Probability that damping results in excitation (driving to the one state) rather than dissipation (driving to the zero state). Set to zero for conventional, dissipative amplitude damping.

Returns:

Quantum operator associated with the channel.

Return type:

intptr_t
