Latest Patents

Tong is associated with 1 patent: “Identifying a Dynamical Decoupling Sequence for Error Suppression of Quantum Computations Using a Genetic Algorithm.” The patent describes a method, system, and computer program product for empirically identifying a dynamical decoupling sequence for a quantum computer.

The approach selects a training quantum circuit with a structure equivalent to the target circuit, then generates a population of candidate sequences represented within a genetic algorithm. Reproduction and mutation produce new candidates from selected sequences, or “parents.” Candidates are evaluated using an objective function, and sequences with suitable fitness may be chosen for further iterations or for use on the target quantum circuit.
