论文摘要
谐波振荡器的挤压状态是连续可变量子传感，计算和通信的核心资源。在这里，我们提出了一种方法，可以通过仅使用Rabi-Type相互作用的汉密尔顿汉顿（Hamiltonian）使用少量振荡器 - Qubit耦合门，以高度挤压抗扩孔的高度挤压真空状态产生一种非常好的近似值。可以使用几种不同的方法来实现这种交互，这先前已经在超导电路和陷阱离子平台中证明。该协议与操纵量子谐波振荡器的其他协议兼容，从而促进了可扩展的连续可变耐故障量子计算。
Squeezed states of harmonic oscillators are a central resource for continuous-variable quantum sensing, computation and communication. Here we propose a method for the generation of very good approximations to highly squeezed vacuum states with low excess anti-squeezing using only a few oscillator-qubit coupling gates through a Rabi-type interaction Hamiltonian. This interaction can be implemented with several different methods, which has previously been demonstrated in superconducting circuit and trapped-ion platforms. The protocol is compatible with other protocols manipulating quantum harmonic oscillators, thus facilitating scalable continuous-variable fault-tolerant quantum computation.
