Promising access to high-speed quantum networks relies on the creation of high-dimensional entangled memories that provide quantum communication with higher capacity of noisy quantum channels, thereby reducing the transmission time of information. Yet, the distribution of multidimensional entanglement between remote memory nodes is still faintly investigated. We propose an experimentally feasible protocol of deterministic generation of high-dimensional entanglement between distant multilevel atoms confined in high-finesse optical cavities and driven by laser pulses. Three-dimensional entanglement is generated deterministically between remote atoms by triggering a two-photon wave packet, which mediates a superposition of states chosen by the laser pulse parameters. The efficient transfer of atomic states between remote nodes allows the construction of a three-dimensional quantum repeater, where the successful creation of entanglement can be verified by a simple method for reliable measurement of atomic ground Zeeman states.

通过多光子交换在遥远的原子记忆之间确定性地产生高维纠缠

对高速量子网络的有希望的访问依赖于高维纠缠存储器的创建，这些存储器提供具有更高容量的噪声量子通道的量子通信，从而减少信息的传输时间。然而，远程内存节点之间的多维纠缠分布仍然被模糊地研究。我们提出了一种实验上可行的协议，用于在高精细光学腔中限制并由激光脉冲驱动的远距离多级原子之间确定性生成高维纠缠。通过触发一个双光子波包，在远程原子之间确定性地产生三维纠缠，它介导了由激光脉冲参数选择的状态叠加。
