Many-Body Super- and Subradiance in Ordered Atomic Arrays
Alec Douglas, Lin Su, Michal Szurek +7
When quantum emitters couple indistinguishably to light, they can synchronize into a collective light matter system with radiative properties profoundly different from those of ind…
A New Angle on Quantum Subspace Diagonalization for Quantum Chemistry
Xeno De Vriendt, Jacob Bringewatt, Nik O. Gjonbalaj +5
Quantum subspace diagonalization and quantum Krylov algorithms offer a feasible, pre- or early-fault tolerant alternative to quantum phase estimation for using quantum computers to…
Probing the Kitaev honeycomb model on a neutral-atom quantum computer
Simon J. Evered, Marcin Kalinowski, Alexandra A. Geim +15
Quantum simulations of many-body systems are among the most promising applications of quantum computers. In particular, models based on strongly-correlated fermions are central to…
Collectively enhanced ground-state cooling in subwavelength atomic arrays
Oriol Rubies-Bigorda, Raphael Holzinger, Ana Asenjo-Garcia +6
Subwavelength atomic arrays feature strong light-induced dipole-dipole interactions, resulting in subradiant collective resonances characterized by narrowed linewidths. In this wor…
Experimental Demonstration of Logical Magic State Distillation
Pedro Sales Rodriguez, John M. Robinson, Paul Niklas Jepsen +70
Realizing universal fault-tolerant quantum computation is a key goal in quantum information science. By encoding quantum information into logical qubits utilizing quantum error cor…
Chirality-induced emergent spin-orbit coupling in topological atomic lattices
Jonah S. Peter, Stefan Ostermann, Susanne F. Yelin
Spin-orbit coupling is of fundamental interest in both quantum optical and condensed matter systems alike. In this work, we show that optically induced electronic excitations in la…
