The Sycamore gate is a two-qubit gate equivalent to FSimGate(π/2, π/6).
The unitary of this gate is
[[1, 0, 0, 0], [0, 0, -1j, 0], [0, -1j, 0, 0], [0, 0, 0, exp(- 1j * π/6)]]This gate can be performed on the Google’s Sycamore chip andis close to the gates that were used to demonstrate quantumsupremacy used in this paper:
- Args:theta: Swap angle on the
|10⟩subspace, in radians.Determined by the strength and duration of the XX+YYinteraction. Note: uses opposite sign convention to theiSWAP gate. Maximum strength (full iswap) is at pi/2.phi: Controlled phase angle, in radians. Determines how much the
|11⟩state is phased. Note: uses opposite sign convention tothe CZPowGate. Maximum strength (full cz) is at pi/2.
controlled([num_controls, control_values, …])Returns a controlled version of this gate. If no arguments are
The number of qubits this gate acts on.
Returns an application of this gate to the given qubits.
Returns a key that differs between non-interchangeable qubits.
Checks if this gate can be applied to the given qubits.
