Bases: object

Decompose two-qubit unitary in terms of a desired $U \sim U_d(\alpha, 0, 0) \sim \text{Ctrl-U}$ gate that is locally equivalent to an RXXGate.

Initialize the KAK decomposition.

Parameters

• rxx_equivalent_gate (Type[Gate]) – Gate that is locally equivalent to an RXXGate: $U \sim U_d(\alpha, 0, 0) \sim \text{Ctrl-U}$ gate. Valid options are [RZZGate, RXXGate, RYYGate, RZXGate, CPhaseGate, CRXGate, CRYGate, CRZGate].
• euler_basis (str) – Basis string to be provided to OneQubitEulerDecomposer for 1Q synthesis. Valid options are ['ZXZ', 'ZYZ', 'XYX', 'XZX', 'U', 'U3', 'U321', 'U1X', 'PSX', 'ZSX', 'ZSXX', 'RR'].

Raises

QiskitError – If the gate is not locally equivalent to an RXXGate.
