U(1) lattice gauge theory and string roughening on a triangular Rydberg array
Lisa Bombieri, Torsten V. Zache, Hannes Pichler +1
Lattice gauge theories (LGTs) describe fundamental interactions in particle physics. A central phenomenon in these theories is confinement, which binds quarks and antiquarks into h…
Rare-Event Quantum Sensing using Logical Qubits
Robert Ott, Torsten V. Zache, Soonwon Choi +2
We present a novel protocol to detect rare signals in a noisy environment using quantum error correction (QEC). The key feature of our protocol is the discrimination between signal…
Non-local mass superpositions and optical clock interferometry in atomic ensemble quantum networks
Charles Fromonteil, Denis V. Vasilyev, Torsten V. Zache +5
Quantum networks are emerging as powerful platforms for sensing, communication, and fundamental tests of physics. We propose a programmable quantum sensing network based on entangl…
Error-corrected fermionic quantum processors with neutral atoms
Robert Ott, Daniel González-Cuadra, Torsten V. Zache +3
Many-body fermionic systems can be simulated in a hardware-efficient manner using a fermionic quantum processor. Neutral atoms trapped in optical potentials can realize such proces…
Quantum simulating continuum field theories with large-spin lattice models
Gabriele Calliari, Marco Di Liberto, Hannes Pichler +1
Simulating the real-time dynamics of quantum field theories (QFTs) is one of the most promising applications of quantum simulators. Regularizing a bosonic QFT for quantum simulatio…
