CliffordUtils

class CliffordUtils(num_qubits=2, group_tables=None, elmnt=None, gatelist=None, elmnt_key=None)[source]

Class for util functions for the Clifford group.

Parameters

  • num_qubits (int) – number of qubits, dimension of the Clifford object.

  • group_tables (dict) – table of all the Clifford objects of a given dimension.

  • elmnt (Clifford) – a Clifford group element.

  • elmnt_key (str) – a unique index of a Clifford object.

  • gatelist (list) – a list of gates corresponding to a Clifford object.
