Abstract
In recent years, there has been significant progress in integrating novel interactions with ultracold atoms to realize exotic phases of strongly correlated matter and perform quantum operations. However, there is still a frontier that largely remains unexplored, associated with achieving strong interactions of long-range character. Although it is well-known that in principle, photon-mediated interactions provide an enabling route, in practice, large and uncontrolled dissipation in the form of atomic spontaneous emission greatly limits what is actually achievable. Our targeted breakthrough is to overcome this barrier by constructing a new platform consisting of a many-atom Ytterbium optical tweezer array integrated with a cavity QED setup. While spontaneous emission typically limits the interaction fidelities of lightmatter coupled systems, our setup will instead harness spontaneous emission as a correlated form of dissipation, which can be suppressed and even utilized for dissipation engineering given the ability to controllably position atoms at sub-wavelength distances. The anticipated increases in interaction fidelities (to the ~99% level), and versatility to design long-range interactions and dissipation, will make such a platform a leading candidate for future applications in quantum simulation and metrology via the ability to produce, investigate, and utilize novel exotic dissipative phases of matter. Such a gain over current capabilities will come from novel experimental advances, a new conceptual paradigm of light-matter interactions, and new theoretical approaches that will be combined together by the diverse QuSiED partners. QuSiED will investigate fundamental problems like the formation of dissipative phases without thermodynamic counterpart, as well as aspects of many-body quantum information science, ranging from entanglement transport in the presence of engineered dissipation to prospects for metrology enhanced by correlated emission. The realization of the unique tweezer-cavity platform will establish a significant advantage for the EU's race for quantum supremacy with the diverse QuSiED consortium creating interdisciplinary knowledge ranging from fundamental to applied aspects of long-range photon-mediated interactions and engineered dissipation.
