Abstract: T66.00004 : Preservation of Quantum States by Local Error Correction on a Two-dimensional Toric Code in a Rydberg Atom Array*
12:06 PM–12:18 PM
Mikhail D Lukin
In this project, we develop a hybrid decoding protocol that performs local error correction with a sequence of local quantum gates before applying traditional global error correction. Based on extensive circuit-level simulations, we show that this hybrid decoding protocol is effective in extending the logical qubit lifetime under the realistic faulty quantum gates with small gate error. Using reinforcement learning, we further optimize the protocol tailored to the Rydberg atom array, and provide estimates on gate fidelities necessary for our scheme to be useful for improving the lifetime of logical qubits and enabling more reliable quantum computation.
