inline Fock(intvec n, intvec m)

Constructor to automatically initialize a Fock state acting on mode m

Parameters

• n – vector<double> of length 1 containing photon number

• m – mode state is initialized on

Throws

std::invalid_argument – cannot have negative Fock state (n < 0)

inline Fock(floatvec n, intvec m)

Constructor that throws an error if real parameters are provided.

Parameters

• n – vector<double> parameters

• m – mode state is initialized on

Throws

invalid_argument – Operation must have integer arguments

inline Fock(complexvec n, intvec m)

Constructor that throws an error if complex parameters are provided.

Parameters

• n – vector<complex> parameters

• m – mode state is initialized on

Throws

invalid_argument – Operation must have integer arguments
