摘要

量子网络可以实现各种应用,如分布式量子计算、远距离量子通信和基于网络的量子传感,并具有前所未有的性能。光子量子存储器是量子网络最重要的构件之一,它是通信通道和本地功能单元之间的接口。一种可编程量子存储器可以处理大量的飞行量子比特流,并满足量子网络中多个核心功能的要求,但这种存储器仍有待实现。在这里,我们报告了一种高性能量子存储器,它可以同时存储由 144 个空间上分离的原子团携带的 72 个光量子比特,并以随机存取的方式支持多达一千次的连续写入或读取操作,比之前的记录大两个数量级。由于具有内置的可编程性,这种量子存储器可以根据需要满足多种功能的要求。作为应用实例,我们实现了量子队列、堆栈和缓冲器,它们与经典信息处理的对应设备非常相似。我们进一步演示了通过存储器存储和重新洗牌四对纠缠的光子脉冲,这些脉冲具有概率到达时间和任意释放顺序,这是实现量子中继器和量子网络高效路由的基本要求。因此,这种多用途可编程量子存储器的实现构成了未来大规模全功能量子网络的关键构件。

Realization of a Programmable Multipurpose Photonic Quantum Memory with Over-Thousand Qubit Manipulations

Realization of a Programmable Multipurpose Photonic Quantum Memory with Over-Thousand Qubit Manipulations
Quantum networks can enable various applications such as distributed quantum computing, long-distance quantum communication, and network-based quantum sensing with unprecedented performances. One of the most important building blocks for a quantum network is a photonic quantum memory which serves as the interface between the communication channel and the local functional unit. A programmable quantum memory which can process a large stream of flying qubits and fulfill the requirements of multiple core functions in a quantum network is still to be realized. Here we report a high-performance quantum memory which can simultaneously store 72 optical qubits carried by 144 spatially separated atomic ensembles and support up to a thousand consecutive write or read operations in a random access way, 2 orders of magnitude larger than the previous record. Because of the built-in programmability, this quantum memory can be adapted on demand for several functions. As example applications, we realize quantum queue, stack, and buffer which closely resemble the counterpart devices for classical information processing. We further demonstrate the storage and reshuffle of four entangled pairs of photonic pulses with probabilistic arrival time and arbitrary release order via the memory, which is an essential requirement for the realization of quantum repeaters and efficient routing in quantum networks. Realization of this multipurpose programmable quantum memory thus constitutes a key enabling building block for future large-scale fully functional quantum networks.
