# 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]

THIS FUNCTION IS DEPRECATED.

IT WILL BE REMOVED IN cirq v0.8.

Use cirq.MatrixGate instead.

Initializes the 2-qubit matrix gate.

Args:
matrix: The matrix that defines the gate.


Methods

 controlled([num_controls, control_values, …]) Returns a controlled version of this gate. If no arguments are 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])
