Circular Rydberg atoms (CRAs), ie, Rydberg atoms with maximal orbital momentum, are
highly promising for quantum computation, simulation, and sensing. They combine long …

The Rydberg blockade is a key ingredient for entangling atoms in arrays. However, it
requires atoms to be spaced well within the blockade radius, which limits the range of local …

Circular Rydberg states are excellent tools for quantum technologies, with large mutual
interactions and long lifetimes in the tens of milliseconds range, 2 orders of magnitude larger …

Divalent atoms provide excellent means for advancing control in Rydberg atom-based
quantum simulation and computing due to the second optically active valence electron …

We discuss monitoring the time evolution of an analog quantum simulator via a quantum
nondemolition (QND) coupling to an auxiliary “clock” qubit. The QND variable of interest is …

Alkaline earth Rydberg atoms are very promising tools for quantum technologies. Their
highly excited outer electron provides them with the remarkable properties of Rydberg atoms …

We propose a ponderomotive trap** mechanism for circular Rydberg atoms that consists
in threading the Rydberg orbital with a tightly focused Gaussian laser beam. The trap …
