论文摘要
提出了一个简单的方案，用于实现可伸缩的原子量子处理器的稳健光学控制的量子门，该方案通过使用光学驻波驱动Qubit。原子局部局部靠近静脉波的抗inos可以实现相对的量子操作，这些量子操作可能比对局部光学相和原子运动敏感的数量级要比相应的波动波构型敏感。该方案与可靠的最佳控制技术和原子阵列中的空间量子量兼容兼容，以实现相控制的操作，而无需紧密的聚焦和控制激光器的精确定位。这对于涉及多普勒敏感光学频率转换的量子门特别有益，并提供了扩大原子量子处理器的所有光学途径。
A simple scheme is presented for realizing robust optically controlled quantum gates for scalable atomic quantum processors by driving the qubits with optical standing waves. Atoms localized close to the antinodes of the standing wave can realize phase-controlled quantum operations that are potentially more than an order of magnitude less sensitive to the local optical phase and atomic motion than corresponding travelling wave configurations. The scheme is compatible with robust optimal control techniques and spatial qubit addressing in atomic arrays to realize phase controlled operations without the need for tight focusing and precise positioning of the control lasers. This will be particularly beneficial for quantum gates involving Doppler sensitive optical frequency transitions and provides an all optical route to scaling up atomic quantum processors.
