OPEN-2QS: towards long observation timescales in trapped ion systems — •Larisa Thorne and Ferdinand Schmidt-Kaler — QUANTUM, Johannes Gutenberg University Mainz, Department of Physics, Staudingerweg 7, Germany
Current state-of-the-art quantum simulators are limited by their short observation times. The OPEN-2QS platform leverages the advantages of Rydberg ions [1] with those of Penning trap configurations [2] to allow significantly longer observation times, up to 7 orders of magnitude longer than microscopic timescales [3]. This will allow us to pursue fundamental research questions previously inaccessible, such as characterizing collective dynamics beyond the decoherence timescale, and exploring non-equilibrium phenomena, particularly those in open many-body quantum systems. In this presentation, I will give an overview of the R&D program at Mainz, including the design of a Penning trap suited to confinement of 40Ca+ Rydberg ions, and updates on the status of the requisite cryogenic components.
