4. 제목: Quantum information processing using Kerr parametric oscillators

A Kerr parametric oscillator(KPO) has been studied for decades, but only recently have its intrinsic quantum properties been recognised as useful for quantum computing, sparking a new wave of research. In this talk, I will introduce the unique properties of this exotic driven quantum system. I will present our experimental demonstration of entanglement-preserving conversion between Fock-state and cat-state encodings, as well as the efficient and straightforward implementation of a universal quantum gate set in the cat-state basis. Lastly, I will discuss our efforts to realisethe simplest autonomous quantum error correction scheme based on this KPO system.
