Out-of-equilibrium dynamics of isolated quantum many-body systems is generally intractable. In chaotic quantum systems, however, local observables rapidly relax to their equilibrium values. Hence, simple translationally-invariant initial states are expected to quickly reach thermal equilibrium for local expectation values. The equilibration of fluctuations on the other hand goes beyond standard thermalization and is expected to happen on much longer timescales, since their approach to equilibrium is limited by the hydrodynamic build-up of large-scale fluctuations.

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: Silicon Vacancy (SiV) centers in diamond coupled to nanophotonic cavities offer a promising platform for quantum communication. Our system utilizes long coherence times, high optical cooperativities, and on-chip scalability, providing a unique path to the practical implementation of long-distance quantum networking.

Abtract: A key question for platforms realizing quantum computation, simulation and communication is: How can we grow the size of a quantum system, while keeping high fidelities of single operations?

Abstract: Primitive asteroids (PAs) are the remaining building blocks of our Solar System (SS) study their composition, location and evolution will help us understanding how different materials travel along the Solar System and how they appeared on Earth. They are characterized by dark surfaces (albedo < 10%) dominated by carbon compounds. Their reflectance spectra are similar to those of carbonaceous chondrites (CCs), the most pristine meteorites in our records, that are abundant in hydrated minerals and organics.

Seminar Abstract:

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).
