cirq.google.XmonDevice

class cirq.google.XmonDevice(measurement_duration: cirq.value.duration.Duration, exp_w_duration: cirq.value.duration.Duration, exp_11_duration: cirq.value.duration.Duration, qubits: Iterable[cirq.devices.grid_qubit.GridQubit])

A device with qubits placed in a grid. Neighboring qubits can interact.

__init__(measurement_duration: cirq.value.duration.Duration, exp_w_duration: cirq.value.duration.Duration, exp_11_duration: cirq.value.duration.Duration, qubits: Iterable[cirq.devices.grid_qubit.GridQubit]) → None

Initializes the description of an xmon device.

Parameters:

• measurement_duration – The maximum duration of a measurement.
• exp_w_duration – The maximum duration of an ExpW operation.
• exp_11_duration – The maximum duration of an ExpZ operation.
• qubits – Qubits on the device, identified by their x, y location.
