Local optimization of quantum circuits

This invention describes a way to make quantum circuits run more efficiently by rearranging their qubits. It works by assigning importance to the connections between qubits based on how many operations are between them, then uses this information to create a new, optimized order for the qubits. The claims narrow this to a specific method for selecting and ordering qubits based on their number of connections and a combined weighting of those connections.

Why it matters: Filed when quantum computing was nascent, the increasing complexity and qubit counts of quantum hardware today make efficient circuit optimization, like this method, far more critical for practical applications.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
