cirq_pasqal.pasqal_gateset.PasqalGateset

A Compilation target intended for Pasqal neutral atom devices.

cirq_pasqal.pasqal_gateset.PasqalGateset(
    include_additional_controlled_ops: bool = True
)

This gateset supports single qubit gates that can be used in a parallel fashion as well as CZ.

This gateset can optionally include CNOT, CCNOT (TOFFOLI) gates, and CCZ as well.

include_additional_controlled_ops Whether to include CCZ, CCNOT, and CNOT gates (defaults to True).

gates

name

num_qubits Maximum number of qubits on which a gate from this gateset can act upon.
postprocess_transformers List of transformers which should be run after decomposing individual operations.
preprocess_transformers List of transformers which should be run before decomposing individual operations.

decompose_to_target_gateset(
    op: 'cirq.Operation', moment_idx: int
) -> cirq_pasqal.pasqal_gateset.DecomposeResult

Method to rewrite the given operation using gates from this gateset.

Args
op cirq.Operation to be rewritten using gates from this gateset.
moment_idx Moment index where the given operation op occurs in a circuit.

Returns

  • An equivalent cirq.OP_TREE implementing op using gates from this gateset.
  • None or NotImplemented if does not know how to decompose op.

validate

validate(
    circuit_or_optree: Union['cirq.AbstractCircuit', op_tree.OP_TREE]
) -> bool

Validates gates forming circuit_or_optree should be contained in Gateset.

Args
circuit_or_optree The cirq.Circuit or cirq.OP_TREE to validate.

with_params

with_params(
    *, name: Optional[str] = None, unroll_circuit_op: Optional[bool] = None
) -> 'Gateset'

Returns a copy of this Gateset with identical gates and new values for named arguments.

If a named argument is None then corresponding value of this Gateset is used instead.

Args
name New name for the Gateset.
unroll_circuit_op If True, new Gateset will recursively validate cirq.CircuitOperation by validating the underlying cirq.Circuit.

Returns
self if all new values are None or identical to the values of current Gateset. else a new Gateset with identical gates and new values for named arguments.

__contains__

__contains__(
    item: Union[raw_types.Gate, raw_types.Operation]
) -> bool

Check for containment of a given Gate/Operation in this Gateset.

Containment checks are handled as follows:

The complexity of the method in terms of the number of gates, n, is

  • O(1) when any default cirq.GateFamily instance accepts the given item, except for an Instance GateFamily trying to match an item with a different global phase.
  • O(n) for all other cases: matching against custom gate families, matching across global phase for the default Instance GateFamily, no match against any underlying gate family.

Args
item The cirq.Gate or cirq.Operation instance to check containment for.

__eq__

__eq__(
    other: _SupportsValueEquality
) -> bool

__ne__

__ne__(
    other: _SupportsValueEquality
) -> bool
