Loads sample Z phase errors for the given device.
cirq_google.engine.load_sample_device_zphase(
    processor_id: str
) -> util.ZPhaseDataType
| Args | 
|---|
| processor_id | name of the processor to simulate. | 
| Returns | 
|---|
| Z phases in the form {gate_type: {angle_type: {qubit_pair: error} } },
where gate_type is "syc" or "sqrt_iswap", angle_type is "zeta" or
"gamma", and "qubit_pair" is a tuple of qubits. | 
| Raises | 
|---|
| ValueError | if processor_id is not a supported QCS processor. |
