论文摘要
我们为Gottesman-Kitaev-Preskill（GKP）介绍了一种新方法，该方法以准确的方式对待其有限能源版本。基于此分析，我们开发了自主稳定GKP歧管的新的Qubit-oscillator电路，从而在不依赖于量子的测量值的情况下纠正了错误。最后，我们以数字显示在GKP状态中编码的逻辑信息在通过这些新电路稳定时，对于典型的振荡器噪声源非常健壮。
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.
