The defining character of quantum mechanics is coherence / the superposition of correlated states of many particles. Quantum correlated and entangled states lie at the heart of several major areas of physics, especially quantum optics, atomic physics and quantum condensed matter. The ability to control precisely a broad range of systems from ultracold atoms in optical lattices to internal states of molecules to semiconductor nanostructures has led to important breakthroughs in the understanding and potential applications of entanglement. Because the same principles underlie the rich but sometimes impenetrable physics of quantum matter, these advances open a window on challenging problems in materials. The fortunate fertility already evident in condensed matter materials suggests strongly that major benefits will accrue from exerting full quantum control of complex systems. Within this project we shall tackle this demanding new challenge. The underlying concepts and technologies of coherent control and manipulation in atomic, molecular and optical physics are now sufficiently established that it is possible to consider the synthesis of designer quantum states of atoms and molecules that can address a number of outstanding problems in condensed matter and optical physics. Furthermore, the ability to build large-scale quantum coherent systems represents such a new capability that we can anticipate new physics, as yet unimagined, as well as new technologies, to emerge.The method of approach will be to increase UK research capacity by the appointment of new faculty and the establishment of state of the art research laboratories and facilities, and the nurturing of collaborative research programs across several institutions. This will be complemented by implementing new training programs at the graduate and postdoctoral researcher level that will be broadly available to the UK community.

量子力学的定义特征是相干性/许多粒子的关联态的叠加。量子关联和纠缠态是物理学的几个主要领域的核心，特别是量子光学、原子物理学和量子凝聚态。从光学晶格中的超冷原子到分子的内态再到半导体纳米结构，精确控制广泛系统的能力导致了对纠缠的理解和潜在应用的重要突破。由于同样的原理构成了丰富但有时令人费解的量子物质物理学的基础，这些进展为我们打开了一扇了解材料中具有挑战性的问题的窗口。在凝聚态物质中已经显而易见的幸运繁殖力强烈地表明，对复杂系统实施完全量子控制将带来重大好处。在这个项目中，我们将应对这一艰巨的新挑战。原子、分子和光学物理中相干控制和操纵的基本概念和技术现在已经充分确立，可以考虑合成原子和分子的设计量子态，这可以解决凝聚态和光学物理中的一些悬而未决的问题。此外，建立大规模量子相干系统的能力代表了一种新的能力，我们可以预见到新的物理学和新技术的出现。方法将是通过任命新的教师，建立最先进的研究实验室和设施，以及在几个机构之间培育合作研究项目，来提高英国的研究能力。作为补充，将在研究生和博士后研究人员层面实施新的培训计划，这些计划将广泛适用于英国社区。
