Abc triples for Bargmann representation

This module contains the (A, b, c) triples for the Fock-Bargmann representation of various states and transformations.

Functions

amplifier_Abc(g)

The (A, b, c) triple of a tensor product of amplifiers.

attenuator_Abc(eta)

The (A, b, c) triple of of a tensor product of atternuators.

attenuator_kraus_Abc(eta)

The entire family of Kraus operators of the attenuator (loss) channel as a single (A, b, c) triple.

beamsplitter_gate_Abc(theta[, phi])

The (A, b, c) triple of a tensor product of two-mode beamsplitter gates.

coherent_state_Abc(x[, y])

The (A, b, c) triple of a tensor product of pure coherent states.

displaced_squeezed_vacuum_state_Abc(x[, y, ...])

The (A, b, c) triple of a tensor product of displazed squeezed vacuum states.

displacement_gate_Abc(x[, y])

The (A, b, c) triple of a tensor product of displacement gates.

displacement_map_s_parametrized_Abc(s, n_modes)

The (A, b, c) triple of a multi-mode s-parametrized displacement map. :math: D_s(vec{gamma}^*, vec{gamma}) = e^{frac{s}{2}|vec{gamma}|^2} D(vec{gamma}^*, vec{gamma}) = e^{frac{s}{2}|vec{gamma}|^2} e^{frac{1}{2}|vec{z}|^2} e^{vec{z}^*vec{gamma} - vec{z} vec{gamma}^*}. The indices of the final triple correspond to the variables \((\gamma_1^*, \gamma_2^*, ..., z_1, z_2, ..., \gamma_1, \gamma_2, ..., z_1^*, z_2^*, ...)\) of the Bargmann function of the s-parametrized displacement map, and correspond to out_bra, in_bra, out_ket, in_ket wires.
