Class Documentation

class blackbird::ThermalLossChannel : public blackbird::Operation

Represents the thermal loss channel For more details, see the Strawberry Fields convention page.

Loss parameter \(T\) and mean thermal population \(\bar{n}\) accessible via:

• \(T\): ThermalLossChannel->f1

• \(\bar{n}\): ThermalLossChannel->f2

Public Functions

inline ThermalLossChannel(complexvec phi, intvec m)

Constructor that throws an error if complex parameters are provided.

Parameters

• phi – vector<complex<double>> parameters

• m – vector<int> containing mode the gate acts on

Throws

invalid_argument – Operation must have real arguments

inline ThermalLossChannel(intvec phi, intvec m)

Constructor that throws an error if complex parameters are provided.

Parameters

• phi – vector<complex<double>> parameters

• m – vector<int> containing mode the gate acts on

Throws

invalid_argument – Operation must have real arguments

inline ThermalLossChannel(floatvec T, intvec m)

Constructor to initialize a thermal loss channel acting on modes m

Parameters

• T – vector<double> of length 2 containing the parameter and thermal population

• m – vector<int> containing mode the gate acts on
