TetrisCNN for interpretable detection of phases of matter from experimental quantum simulator data

Kacper Cybiński, Björn van Zwol, James Enouen +5

Detecting phases of matter in general relies on identifying the correct order parameter - a task that remains notoriously difficult for unknown transitions and traditionally is gui…

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…

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…

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…

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…

Benchmarking direct and indirect dipolar spin-exchange interactions between two Rydberg atoms

Gabriel Emperauger, Mu Qiao, Guillaume Bornet +8

We report on the experimental characterization of various types of spin-exchange interactions between two individual atoms, where pseudo-spin degrees of freedom are encoded in diff…

Tomonaga-Luttinger Liquid Behavior in a Rydberg-encoded Spin Chain

Gabriel Emperauger, Mu Qiao, Cheng Chen +14

Quantum fluctuations can disrupt long-range order in one-dimensional systems, and replace it with the universal paradigm of the Tomonaga-Luttinger liquid (TLL), a critical phase of…

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…

Spin-1 Haldane phase in a chain of Rydberg atoms

J. Mögerle, K. Brechtelsbauer, A. T. Gea-Caballero +7

We present a protocol to implement a spin-1 chain in Rydberg systems using three Rydberg states close to a Förster resonance. In addition to dipole-dipole interactions, strong van…

Transformer neural networks and quantum simulators: a hybrid approach for simulating strongly correlated systems

Hannah Lange, Guillaume Bornet, Gabriel Emperauger +5

Owing to their great expressivity and versatility, neural networks have gained attention for simulating large two-dimensional quantum many-body systems. However, their expressivity…

Enhancing a Many-body Dipolar Rydberg Tweezer Array with Arbitrary Local Controls

Guillaume Bornet, Gabriel Emperauger, Cheng Chen +8

We implement and characterize a protocol that enables arbitrary local controls in a dipolar atom array, where the degree of freedom is encoded in a pair of Rydberg states. Our appr…

Spectroscopy of elementary excitations from quench dynamics in a dipolar XY Rydberg simulator

Cheng Chen, Gabriel Emperauger, Guillaume Bornet +11

We use a Rydberg quantum simulator to demonstrate a new form of spectroscopy, called quench spectroscopy, which probes the low-energy excitations of a many-body system. We illustra…

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…

Continuous Symmetry Breaking in a Two-dimensional Rydberg Array

Cheng Chen, Guillaume Bornet, Marcus Bintz +13

Spontaneous symmetry breaking underlies much of our classification of phases of matter and their associated transitions. The nature of the underlying symmetry being broken determin…
