Event description: 
Autonomous quantum error correction in a bosonic qubit with dissipation engineering

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 experimental demonstration of autonomous quantum error correction (AQEC) by tailoring dissipation within the quantum system.  Our AQEC is realized by a synthetic dissipation operator activated via continuous-wave drives only, which stabilizes the photon number parity of a superconducting cavity, hence correcting for the dominant single-photon loss errors in the system.  We will further discuss the role of dissipation engineering as a resource-efficient alternative or supplement to active QEC in bosonic qubits and logic gates.
