高能Gottesman-Kitaev-Preskill态的稳定化

Stabilization of Finite-Energy Gottesman-Kitaev-Preskill States

Baptiste Royer, Shraddha Singh, S. M. Girvin

摘要:

我们介绍了一种新的方法Gottesman-Kitaev-Preskill(GKP)状态,以精确的方式对待他们的有限能量版本。基于这种分析,我们开发了新的量子位振荡器电路,可以自主稳定GKP流形,在不依赖量子位测量的情况下纠正错误。最后,我们数值计算表明,在GKP状态编码的逻辑信息是非常强大的,对典型的振荡器噪声源时,这些新的电路稳定。

英文摘要:

We introduce a new approach to Gottesman-Kitaev-Preskill (GKP) states that treats their finite-energy version in an exact manner. Based on this analysis, we develop new qubit-oscillator circuits that autonomously stabilize a GKP manifold, correcting errors without relying on qubit measurements. Finally, we show numerically that logical information encoded in GKP states is very robust against typical oscillator noise sources when stabilized by these new circuits.
