qib.operator.gates.Gate

class qib.operator.gates.Gate

Bases: AbstractOperator

Parent class for quantum gates.

A quantum gate represents the corresponding unitary operation, and can store the qubits (or in general quantum particles) it acts on.

Methods

as_circuit_matrix	Generate the sparse matrix representation of the gate as element of a quantum circuit.
as_matrix	Generate the (sparse) matrix representation of the operator.
as_qasm	Generate a Qobj OpenQASM representation of the gate.
as_tensornet	Generate a tensor network representation of the gate, using an individual tensor axis for each wire.
fields	Return the list of fields hosting the quantum particles which the gate acts on.
inverse	Return the inverse operator.
is_hermitian	Whether the operator is Hermitian.
is_unitary	A quantum gate is unitary by definition.
particles	Return the list of quantum particles the gate acts on.
