cirq.google.optimized_for_sycamore(circuit: cirq.Circuit, *, new_device: Optional[cirq.google.XmonDevice] = None, qubit_map: Callable[cirq.Qid, cirq.devices.grid_qubit.GridQubit] = <function <lambda>>, optimizer_type: str = 'sqrt_iswap', tolerance: float = 1e-05, tabulation_resolution: Optional[float] = None)cirq.Circuit[source]

Optimizes a circuit for Google devices.

Uses a set of optimizers that will compile to the proper gateset for the
device (xmon, sqrt_iswap, or sycamore gates) and then use optimizers to
compresss the gate depth down as much as is easily algorithmically possible
by merging rotations, ejecting Z gates, etc.
Parameters
  • circuit – The circuit to optimize.

  • new_device – The device the optimized circuit should be targeted at. If set to None, the circuit’s current device is used.

  • qubit_map – Transforms the qubits (e.g. so that they are GridQubits).

  • optimizer_type – A string defining the optimizations to apply. Possible values are ‘xmon’, ‘xmon_partial_cz’, ‘sqrt_iswap’, ‘sycamore’

  • tolerance – The tolerance passed to the various circuit optimization passes.

  • tabulation_resolution – If provided, compute a gateset tabulation with the specified resolution and use it to approximately compile arbitrary two-qubit gates for which an analytic compilation is not known.

Returns

The optimized circuit.
