quara.objects.qoperation_typical module

generate_effective_lindbladian_object(gate_name, object_name, dims=None, ids=None, c_sys=None, is_physicality_required=True)

Return an effective-llindbladian-related object.

Parameters

• gate_name (str) – The list of valid gate_name is given by quara.objects.gate_typical.get_gate_names().

• object_name (str) – The list of valid object_name is given by get_effective_lindbladian_object_names().

• dims (List[int] = None, Optional) – To be given for gate_name = ‘identity’

• ids (List[int] = None, Optional) – This is a list of elmental system’s ids. To be given for specific asymmetric multi-partite gates For example, in the case of gate_name = ‘cx’, id[0] is for the id of the control qubit and id[1] is for the id of the target qubit.

• c_sys (CompositeSystem = None, Optional) – To be given for object_name = ‘effective_lindbladian’

• is_physicality_required (bool = True) – whether the generated object is physicality required, by default True
