The project addresses two important open problems in ultracold atomic physics relatedto the general goals of quantum computation and quantum-limited precisionmeasurement: (I) developing a hybrid atom-photon interferometer for quantum-limitedmeasurements of environmental properties, and (II) developing Interaction-Freequantum gates for deterministic long distance teleportation of atomic qubits. Bothproblems make use of the fact that atoms are ideal qubits and/or probes of theenvironment,whereas photons are the best choice for transmitting quantum information.

该项目解决了超冷原子物理学中与量子计算和量子有限精密测量的总体目标相关的两个重要的开放问题：（I）开发混合原子光子干涉仪，用于环境特性的量子有限测量，以及（II）开发无相互作用量子用于原子量子位的确定性长距离隐形传态的门。这两个问题都利用了这样一个事实：原子是理想的量子位和/或环境的探针，而光子是传输量子信息的最佳选择。
