Dirac Spin Liquid Candidate in a Rydberg Quantum Simulator
Guillaume Bornet, Marcus Bintz, Cheng Chen +10
We experimentally investigate a frustrated spin-exchange antiferromagnet in a quantum simulator, composed of N = 114 dipolar Rydberg atoms arranged into a kagome array. Motivated b…
Logical qubits with erasure conversion using metastable neutral atoms
Bichen Zhang, Genyue Liu, Guillaume Bornet +6
Implementing large-scale quantum algorithms with practical advantage will require fault-tolerance achieved through quantum error correction, but the associated overhead is prohibit…
High-fidelity neutral atom gates leveraging low-rank Hessian optimization
Genyue Liu, Guillaume Bornet, Deniz Kurdak +4
Quantum optimal control can produce fast and robust multi-qubit gates, but experimentally calibrating the resulting high-dimensional waveforms remains challenging because direct se…
Observing weakly broken conservation laws in a dipolar Rydberg quantum spin chain
Cheng Chen, Luca Capizzi, Alice Marché +6
Integrable quantum many-body systems host families of extensive conservation laws, some of which are fragile: even infinitesimal perturbations can qualitatively alter their dynamic…
Probing spin-motion coupling of two Rydberg atoms by a Stern-Gerlach-like experiment
Gabriel Emperauger, Mu Qiao, Guillaume Bornet +7
We propose and implement a protocol to measure the state-dependent motion of Rydberg atoms induced by dipole-dipole interactions. Our setup enables simultaneous readout of both the…
Realization of a doped quantum antiferromagnet with dipolar tunnelings in a Rydberg tweezer array
Mu Qiao, Gabriel Emperauger, Cheng Chen +13
Doping an antiferromagnetic Mott insulator is central to our understanding of a variety of phenomena in strongly-correlated electrons, including high-temperature superconductors. T…
