EquivalenceLibrary¶

class EquivalenceLibrary(*, base=None)[source]¶

A library providing a one-way mapping of Gates to their equivalent implementations as QuantumCircuits.

Create a new equivalence library.

Parameters: base (Optional[EquivalenceLibrary]) – Base equivalence library to will be referenced if an entry is not found in this library.

Methods

`EquivalenceLibrary.add_equivalence`(gate, …)	Add a new equivalence to the library.
`EquivalenceLibrary.get_entry`(gate)	Gets the set of QuantumCircuits circuits from the library which equivalently implement the given Gate.
`EquivalenceLibrary.has_entry`(gate)	Check if a library contains any decompositions for gate.
`EquivalenceLibrary.set_entry`(gate, entry)	Set the equivalence record for a Gate.
