论文摘要
我们提出了一种玻色词二项式代码非绝热纯量量子计算的方案，该系统由人工原子超构成与空腔谐振器组成的系统。在我们的协议中，由Fock状态的叠加形成的二项式代码可以大大节省物理资源以纠正量子计算中的错误。我们适用于通过快捷方式到绝热方法设计的强大驾驶场。这将栅极的时间减少到数十纳秒。随着时间的推移积累的系统的破坏性可以通过这种快速演变有效地降低。通过系统纠正的敏感性取消化方法可以抑制由控制缺陷引起的噪声，因此该协议主要对这种噪声不敏感。结果，该协议可以迅速（$ \ sim 35 $ ns）产生容忍和高保真性（$ \ gtrsim 98 \％$，具有实验现实的参数）量子门。
We propose a protocol for bosonic binomial-code nonadiabatic holonomic quantum computation in a system composed of an artificial atom ultrastrongly coupled to a cavity resonator. In our protocol, the binomial codes, formed by superpositions of Fock states, can greatly save physical resources to correct errors in quantum computation. We apply to the system strong driving fields designed by shortcuts-to-adiabatic methods. This reduces the gate time to tens of nanoseconds. Decoherence of the system accumulated over time can be effectively reduced by such a fast evolution. Noise induced by control imperfections can be suppressed by a systematic-error-sensitivity nullification method, thus the protocol is mostly insensitive to such noises. As a result, this protocol can rapidly ($\sim 35$ ns) generate fault-tolerant and high-fidelity ($\gtrsim 98\%$ with experimentally realistic parameters) quantum gates.
