Abstract: One-dimensional systems exhibiting a continuous symmetry can host quantum phases of matter with true long-range order only in the presence of sufficiently long-range interactions. In most physical systems, however, the interactions are short-ranged, hindering the emergence of such phases in one dimension.
Abstract: Rydberg atom arrays have emerged as a promising candidate for quantum computation. However, scaling up the platform beyond a few thousand qubits would require a modular approach. An integrated optical cavity could serve as a quantum networking node between distant quantum processors. In this talk, I will show our results towards this integration for two candidate platforms: a nano-photonic crystal cavity (PCC) and a Fabry-Perot Fiber cavity (FPFC). In our lab, we have already demonstrated all the necessary quantum networking capabilities of the PCC for ground-state atoms.
Klaus Mølmer, one of our current Visiting Fellows, will be giving a talk on Tuesday, 4/25 at 2 pm in the JILA Auditorium. Please mark your calendars and come hear about Dr. Mølmer’s work! There will also be a reception with cake in the h-bar (3rd floor, X-wing) following the talk.
Followed by a reception in the h-bar (with cake) at 3 pm.

Strong quantum correlations lie in the center of many fascinating physical phenomena, as for instance quantum phase transitions. A direct way to study quantum correlations in many body systems is to compute certain observables with the respective wave function. Yet, it is known that reduced density matrices are able to describe and predict directly the bulk of physical features of such quantum phenomena, overcoming the curse of dimensionality of wave-function-based theories.
