Coherent control of subradiant excitations in atomic rings
Milena Djatchkova, Igor Lesanovsky, Beatriz Olmos
Collective excitations in ordered subwavelength atomic arrays can exhibit strongly suppressed radiative decay due to interference between light scattered by neighboring emitters. T…
Non-equilibrium exciton dynamics in tailored molecular potentials of Rydberg ion crystals
Simon Euchner, Mathias B. M. Svendsen, Igor Lesanovsky
Trapped ions excited to high-lying electronic states combine strongly coupled collective vibrational and electronic degrees of freedom with long-ranged interparticle interactions.…
Thermometry for a Kagome Lattice Dipolar Rydberg Simulator
Erik Fitzner, Igor Lesanovsky, Björn Sbierski
We propose an accurate thermometry approach for Rydberg atom tweezer arrays combining data from correlation and local susceptibility measurements with a theoretical high-temperatur…
Harnessing Floquet dynamics for selective metrology in few-qubit systems
Asghar Ullah, Hasan Mermer, Melih Ãzkurt +2
Periodically driven quantum systems can function as highly selective parameter filters. We demonstrate this capability in a finite-size, three-qubit system described by the transve…
Quantum simulation with Rydberg ions in a Penning trap
Wilson S. Martins, Markus Hennrich, Ferdinand Schmidt-Kaler +1
Quantum simulation of interacting many-body spin systems is routinely performed with cold trapped ions, and systems with hundreds of spins have been studied in one and two dimensio…
Fast Native Three-Qubit Gates and Fault-Tolerant Quantum Error Correction with Trapped Rydberg Ions
Katrin Bolsmann, Thiago L. M. Guedes, Weibin Li +3
Trapped ions as one of the most promising quantum-information-processing platforms, yet conventional entangling gates mediated by collective motion remain slow and difficult to sca…
