cirq_google.engine.virtual_engine_factory.extract_gate_times_ns_from_device

Extract a dictionary of gate durations in nanoseconds from GridDevice object.

cirq_google.engine.virtual_engine_factory.extract_gate_times_ns_from_device(
    device: cirq_google.GridDevice
) -> dict[type[cirq.Gate], float]

The durations are obtained from GridDevice.metadata field which is provided for devices obtained with create_device_from_processor_id.

Args
`device`	Object representing Google devices with a grid qubit layout.

Returns
A dictionary of gate durations versus supported gate types. Returns an empty dictionary when `device.metadata` do not provide gate durations.
