cirq.optimizers.MergeInteractions

Combines series of adjacent one- and two-qubit, non-parametrized gates

Inherits From: MergeInteractionsAbc, PointOptimizer

operating on a pair of qubits and replaces each series with the minimum number of CZ gates.

tolerance A limit on the amount of absolute error introduced by the construction.
allow_partial_czs Enables the use of Partial-CZ gates.
post_clean_up This function is called on each set of optimized operations before they are put into the circuit to replace the old operations.

Methods

optimization_at

View source

Describes how to change operations near the given location.

For example, this method could realize that the given operation is an X gate and that in the very next moment there is a Z gate. It would indicate that they should be combined into a Y gate by returning PointOptimizationSummary(clear_span=2, clear_qubits=op.qubits, new_operations=cirq.Y(op.qubits[0]))

Args
circuit The circuit to improve.
index The index of the moment with the operation to focus on.
op The operation to focus improvements upon.

Returns
A description of the optimization to perform, or else None if no change should be made.
