QasmQobjInstruction

class 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)

A class representing a single instruction in an QasmQobj Experiment.

Instatiate 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 of int containing the list of register slots in which to store the measurement results (must be the same length as qubits). If a bfunc instruction this is a single int of the register slot in which to store the result.
• memory (list) – If a measure instruction this is a list of int containing the list of memory slots to store the measurement results in (must be the same length as qubits). If a bfunc instruction this is a single int of the memory slot to store the boolean function result in.
• condition (tuple) – A tuple of the form (int, int) where the first int is the control register and the second int 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 an AND 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
