Quantum simulations of non-ergodic phenomena with trapped ions
Recent years have seen the development of isolated quantum simulator platforms capable of exploring interesting questions at the frontiers of many-body physics. We describe our platform, based on a chain of Ytterbium ions in a linear trap, and describe its capabilities, which include long-range spin-spin interactions and single-site manipulation and readout. We then describe some recent studies undertaken with this machine, focusing on two.
All-optical noise spectroscopy of a solid-state spin
The development of spin qubits with long coherence times for quantum information processing requires sources of spin noise to be identified and minimized. Although microwave-based spin control is typically used to extract the noise spectrum, this becomes infeasible when high frequency noise components are stronger than the available microwave power. Here, we introduce an all-optical approach for noise spectroscopy of spin qubits based on Raman spin rotation using Carr-Purcell-Meiboom-Gill (CPMG) pulse sequences.
Overview of quantum research at UMD
This short talk provides a snapshot of opportunities in quantum science, technology, engineering, and mathematics (qSTEM) at the University of Maryland College Park (UMD). The UMD quantum ecosystem consists of seven quantum institutes, five quantum-adjacent institutes, and approximately 100 faculty, split 55/45 between theory and experiment. I organize the ecosystem into subfields: each subfield is described, and its corresponding faculty is listed.
Pizza and drinks served after the talk. This talk will start at 12:10 p.m.
