Devices based on Entanglement in Cold Arrays of Trapped Atoms

量子物理不仅涉及非常小的系统或少量能量的物理学，还涉及导致纠缠的粒子和场之间的微妙关联。为量子应用创造大规模的纠缠原子阵列既是高度热门的，也是具有挑战性的。量子模拟涉及到量子系统对其他量子系统的模拟，它刚刚成为一种强大的新计算工具，但量子信息处理(QIP)有许多尚未实现的应用。在此背景下，这一提议旨在用量子光学的新工具来改造前景光明的原子芯片技术。我们将设计大量原子纠缠的方法，并将其应用于理想的和可实现的量子设备：例如，高精度干涉仪、运动传感器、大规模量子模拟的现实设计，以及导致量子处理器的量子逻辑模块。将制定控制和捕获阵列中冷原子的工具，并将为将原子捕获到微加工表面上方的微结构进行新的设计。在进一步的商业开发之后，拟议的设备具有许多终端用户应用，包括旋转传感和导航、矿产和石油勘探、解密和搜索未排序的列表。

Quantum physics involves not only the physics of very small systems, or small amounts of energy, but also subtle correlations between particles and fields which result in entanglement. Creating large-scale arrays of entangled atoms for quantum applications is both highly topical and challenging. Quantum simulations, which involve quantum systems modelling other quantum systems, are just emerging as a powerful new tool of calculation, and yet quantum information processing (QIP) has many unrealized applications. In this context this proposal aims to transform the promising atom chip technology with new tools from quantum optics. We will design methods for entangling large numbers of atoms with applications to desirable and realizable quantum devices: e.g. high precision interferometers, motion sensors, realistic designs for large-scale quantum simulations, and quantum logic modules leading to quantum processors. Tools for controlling and trapping cold atoms in arrays will be formulated - and new designs for micro-structures that trap atoms above micro-fabricated surfaces will be made. After further commercial development the proposed devices have a number of end-user applications including rotation sensing and navigation, mineral and petroleum prospecting, decryption, and searching unsorted lists.
