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…
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…
Probing electronic state-dependent conformational changes in a trapped Rydberg ion Wigner crystal
Marion Mallweger, Natalia Kuk, Vinay Shankar +6
State-dependent conformational changes play a central role in molecular dynamics, yet they are often difficult to observe or simulate due to their complexity and ultrafast nature.…
Rydberg atom arrays as quantum simulators for molecular dynamics
Simon Euchner, Igor Lesanovsky
Rydberg atoms held in optical tweezer arrays combine vibrational and electronic degrees of freedom which can be coupled and manipulated at a microscopic level. This opens opportuni…
