Public Functions

inline CKgate(complexvec s, intvec m)

Constructor that throws an error if complex parameters are provided.

Parameters

• s – vector<complex<double>> parameters

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

Throws

invalid_argument – Operation must have real arguments

inline CKgate(intvec s, intvec m)

Constructor that throws an error if integer parameters are provided.

Parameters

• s – vector<int> parameters

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

Throws

invalid_argument – Operation must have real arguments

inline CKgate(floatvec s, intvec m)

Constructor to initialize a CKgate acting on modes m

Parameters

• s – vector<double> of length 1 containing the parameter :math:\kappa
