class qib.circuit.circuit.Circuit(gates: Sequence[Gate | ControlInstruction] | None = None)

Bases: object

A quantum circuit consists of a list of quantum gates and control instructions (e.g. measure, barrier, delay, etc.).

We follow the convention that the first gate in the list is applied first.

Methods

append_circuit	Append the gates from another quantum circuit to the current circuit.
append_gate	Append a quantum gate or a control instruction.
as_matrix	Generate the sparse matrix representation of the circuit.
as_qasm	Generate a list of Qobj OpenQASM instructions representation of the circuit.
as_tensornet	Generate a tensor network representation of the circuit.
clbits	Set of all classical bits appearing in the circuit.
fields	List of all fields appearing in the circuit.
inverse	Construct the "inverse" circuit: reversed list of adjoint gates.
particles	Set of all quantum particles appearing in the circuit.
prepend_circuit	Prepend the gates from another quantum circuit to the current circuit.
prepend_gate	Prepend a quantum gate or a control instruction.
