US Patent 11281988 Re-generation of a gate-level quantum circuit based on gate-level analysis

A method, system and product comprising: obtaining a functional-level representation of a quantum circuit that comprises a functional block; synthesizing a gate-level representation of the quantum circuit based on the functional-level representation of the quantum circuit, wherein the gate-level representation of the quantum circuit comprises a first sub-circuit and a second sub-circuit; providing the gate-level representation to a gate-level processing component; obtaining, from the gate-level processing component, a change indication indicating that the gate-level processing component modified the first sub-circuit, whereby determining a modified first sub-circuit; in response to the change indication, synthesizing a modified second sub-circuit based on a knowledge of an existence of the modified first sub-circuit.
