# cirq.TwoQubitMatrixGate¶

class cirq.TwoQubitMatrixGate(matrix: numpy.ndarray)[source]

A 2-qubit gate defined only by its matrix.

More general than specialized classes like CZPowGate, but more expensive
and more float-error sensitive to work with (due to using
eigendecompositions).
__init__(matrix: numpy.ndarray) → None[source]

Initializes the 2-qubit matrix gate.

Parameters

matrix – The matrix that defines the gate.

Methods

 controlled_by(*control_qubits[, control_values]) Returns a controlled version of this gate. The number of qubits this gate acts on. on(*qubits) Returns an application of this gate to the given qubits. validate_args(qubits) Checks if this gate can be applied to the given qubits. wrap_in_linear_combination([coefficient])
