cirq.create_transformer_with_kwargs
Method to capture additional keyword arguments to transformers while preserving mypy type.
cirq.create_transformer_with_kwargs(
transformer: 'cirq.TRANSFORMER', **kwargs
) -> 'cirq.TRANSFORMER'
Returns a cirq.TRANSFORMER
which, when called with a circuit and transformer context, is
equivalent to calling transformer(circuit, context=context, **kwargs)
. It is often useful to
capture keyword arguments of a transformer before passing them as an argument to an API that
expects cirq.TRANSFORMER
. For example:
def run_transformers(transformers: 'List[cirq.TRANSFORMER]'):
circuit = cirq.Circuit(cirq.X(cirq.q(0)))
context = cirq.TransformerContext()
for transformer in transformers:
transformer(circuit, context=context)
transformers: 'List[cirq.TRANSFORMER]' = []
transformers.append(
cirq.create_transformer_with_kwargs(
cirq.expand_composite, no_decomp=lambda op: cirq.num_qubits(op) <= 2
)
)
transformers.append(cirq.create_transformer_with_kwargs(cirq.merge_k_qubit_unitaries, k=2))
run_transformers(transformers)
Args |
transformer
|
A cirq.TRANSFORMER for which additional kwargs should be captured.
|
**kwargs
|
The keyword arguments which should be captured and passed to transformer .
|
Returns |
A cirq.TRANSFORMER method transformer_with_kwargs , s.t. executing
transformer_with_kwargs(circuit, context=context) is equivalent to executing
transformer(circuit, context=context, **kwargs) .
|
Raises |
SyntaxError
|
if **kwargs contain a 'context'.
