cirq.drop_negligible_operations

Removes operations with tiny effects.

cirq.drop_negligible_operations(
    circuit: 'cirq.AbstractCircuit',
    *,
    context: Optional['cirq.TransformerContext'] = None,
    atol: float = 1e-08
) -> 'cirq.Circuit'

Circuit Transformers Circuit optimization, gate alignment, and spin echoes Circuits 2: Linear Trotter steps of diagonal Coulomb operators Circuits 3: Low rank, arbitrary basis molecular simulations

An operation op is considered to have a tiny effect if cirq.trace_distance_bound(op) <= atol.

Args
`circuit`	Input circuit to transform.
`context`	`cirq.TransformerContext` storing common configurable options for transformers.
`atol`	Absolute tolerance to determine if an operation `op` is negligible -- i.e. if `cirq.trace_distance_bound(op) <= atol`.

Returns
Copy of the transformed input circuit.
