Class Documentation

class blackbird::BSgate : public blackbird::Operation

Represents the beamsplitter. For more details, see the Strawberry Fields convention page.

Beamsplitter parameters \(\theta\) and \(\phi\) accessible via:

• \(\theta\): BSgate->f1

• \(\phi\): BSgate->f1

Public Functions

inline BSgate(complexvec theta_phi, intvec m)

Constructor that throws an error if complex parameters are provided.

Parameters

• theta_phi – vector<complex<double>> parameters

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

Throws

invalid_argument – Operation must have real arguments

inline BSgate(intvec theta_phi, intvec m)

Constructor that throws an error if integer parameters are provided.

Parameters

• theta_phi – vector<int> parameters

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

Throws

invalid_argument – Operation must have real arguments

inline BSgate(floatvec theta_phi, intvec m)

Constructor to initialize a BSgate acting on modes m

Parameters

• theta_phi – vector<double> of length 2 containing the beamsplitter angle and phase

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