Autonomous quantum error correction with superconducting qubits
ORAL
Abstract
Quantum error correction is of vital importance for the successful performance of quantum information tasks. Based on recent work [1], we propose a superconducting circuit with flux-driven Josephson qubits capable of autonomously protecting many-body states against bit-flip errors. Unlike the traditional error correction schemes where feed-back operations are applied conditioned on the measurements, in our circuit, error correction is achieved by tailoring interactions between low-Q resonators (the ``shadow lattice'') and sinusoidally flux-driven qubits. An energetic resonance condition minimizes errors generated by the resonator coupling itself while still allowing for rapid error correction. In this talk, I will introduce our autonomous quantum error correction scheme, and present our fabricated superconducting circuit. I will also discuss preliminary results obtained from our experiments. \\[4pt] [1] Phys. Rev. X 4, 031039 (2014)
