class qib.operator.control_instructions.ControlInstruction

Bases: AbstractOperator

Parent class for circuit control instructions.

A control instruction is an operational directive in a quantum program (i.e. circuit), that dictates specific actions to be carried out on qubits within a quantum processor.

Methods

as_matrix	Instructions in quantum circuits do not have a sparse matrix representation, because they are not quantum operations that act on the state of qubits.
as_qasm	Generate a Qobj OpenQASM representation of the instruction.
fields	List of all fields appearing in the instruction.
is_hermitian	A control instruction is never Hermitian.
is_unitary	A control instruction is never unitary.
on	Apply the instruction on the specified qubits.
particles	Return the list of quantum particles the instruction is applied on.

Attributes

num_wires

The number of "wires" (or quantum particles) this instruction is applied on.

as_matrix()

Instructions in quantum circuits do not have a sparse matrix representation, because they are not quantum operations that act on the state of qubits. Instead, these instructions serve as control directives within a quantum circuit.

as_qasm()

Generate a Qobj OpenQASM representation of the instruction.

abstract fields()

List of all fields appearing in the instruction.

is_hermitian()

A control instruction is never Hermitian.

is_unitary()

A control instruction is never unitary.

abstract property num_wires

The number of “wires” (or quantum particles) this instruction is applied on.

abstract on(qubits: Sequence[Qubit])

Apply the instruction on the specified qubits.

abstract particles()

Return the list of quantum particles the instruction is applied on.
