Scalable spin squeezing in a dipolar Rydberg atom array
Guillaume Bornet, Gabriel Emperauger, Cheng Chen +11
The standard quantum limit bounds the precision of measurements that can be achieved by ensembles of uncorrelated particles. Fundamentally, this limit arises from the non-commuting…
Experimentally accessible scheme for a fractional Chern insulator in Rydberg atoms
Sebastian Weber, Rukmani Bai, Nastasia Makki +6
We present a setup with Rydberg atoms for the realization of a bosonic fractional Chern insulator in artificial matter. The suggested setup relies on Rydberg atoms arranged in a ho…
Programmable quantum simulation of 2D antiferromagnets with hundreds of Rydberg atoms
Pascal Scholl, Michael Schuler, Hannah J. Williams +9
Quantum simulation using synthetic systems is a promising route to solve outstanding quantum many-body problems in regimes where other approaches, including numerical ones, fail. M…
Quantum computing with neutral atoms
Loic Henriet, Lucas Beguin, Adrien Signoles +4
The manipulation of neutral atoms by light is at the heart of countless scientific discoveries in the field of quantum physics in the last three decades. The level of control that…
Realization of a density-dependent Peierls phase in a synthetic, spin-orbit coupled Rydberg system
Vincent Lienhard, Pascal Scholl, Sebastian Weber +8
We experimentally realize a Peierls phase in the hopping amplitude of excitations carried by Rydberg atoms, and observe the resulting characteristic chiral motion in a minimal setu…
Experimental realization of a symmetry protected topological phase of interacting bosons with Rydberg atoms
Sylvain de Léséleuc, Vincent Lienhard, Pascal Scholl +6
The concept of topological phases is a powerful framework to characterize ground states of quantum many-body systems that goes beyond the paradigm of symmetry breaking. While a few…
