Title:Â Autonomous quantum error correction for bosonic qubits
Abstract: Quantum error correction is usually implemented via an active schedule of discrete error syndrome measurements and adaptive recovery operations which are hardware intensive and prone to introducing and propagating errors. In this talk, we will discuss our recent series of experiments tailoring continuous dissipative processes in superconducting circuit QED to implement autonomous error correction for qubits encoded in bosonic cavity states. We will focus on two generations of experiments realizing the Parity Recovery by Selective Photon Addition (PReSPA) operator, which stabilizes the photon number parity, hence correcting for the dominant single-photon loss errors in the 4-component cat code and the binomial code. We will also discuss our ongoing effort towards dissipative stabilization of multi-mode bosonic qubits.
