摘要:

量子计算和通信依赖于稳健且高保真地操纵量子态的能力。因此,需要某种形式的纠错来保护脆弱的量子叠加态免受所谓的退相干噪声的破坏。事实上,量子纠错(QEC)的发现将量子信息领域从学术好奇心转变为发展中的技术。在这里,我们提出了一个连续变量的QEC码的实验实现,9个光束之间的纠缠的基础上。原则上,Shor最初的9量子比特方案的9波包适应允许针对任意单光束(单方)错误的完全量子纠错。

英文摘要:

Quantum computation and communication rely on the ability to manipulate quantum states robustly and with high fidelity. Thus, some form of error correction is needed to protect fragile quantum superposition states from corruption by so-called decoherence noise. Indeed, the discovery of quantum error correction (QEC) turned the field of quantum information from an academic curiosity into a developing technology. Here we present a continuous-variable experimental implementation of a QEC code, based upon entanglement among 9 optical beams. In principle, this 9-wavepacket adaptation of Shor's original 9-qubit scheme allows for full quantum error correction against an arbitrary single-beam (single-party) error.
