QasmQobjInstruction
class qiskit.qobj.QasmQobjInstruction(name, params=None, qubits=None, register=None, memory=None, condition=None, conditional=None, label=None, mask=None, relation=None, val=None, snapshot_type=None)
Bases: object
A class representing a single instruction in an QasmQobj Experiment.
Instantiate a new QasmQobjInstruction object.
Parameters
- name (str) – The name of the instruction
- params (list) – The list of parameters for the gate
- qubits (list) – A list of
int
representing the qubits the instruction operates on - register (list) – If a
measure
instruction this is a list ofint
containing the list of register slots in which to store the measurement results (must be the same length as qubits). If abfunc
instruction this is a singleint
of the register slot in which to store the result. - memory (list) – If a
measure
instruction this is a list ofint
containing the list of memory slots to store the measurement results in (must be the same length as qubits). If abfunc
instruction this is a singleint
of the memory slot to store the boolean function result in. - condition (tuple) – A tuple of the form
(int, int)
where the firstint
is the control register and the secondint
is the control value if the gate has a condition. - conditional (int) – The register index of the condition
- label (str) – An optional label assigned to the instruction
- mask (int) – For a
bfunc
instruction the hex value which is applied as anAND
to the register bits. - relation (str) – Relational operator for comparing the masked register to the
val
kwarg. Can be either==
(equals) or!=
(not equals). - val (int) – Value to which to compare the masked register. In other words, the output of the function is
(register AND mask)
- snapshot_type (str) – For snapshot instructions the type of snapshot to use
