Covariant Approximate Quantum Codes for Protected Analog Computation
Mariia Elovenkova, Hong-Ye Hu, Susanne F. Yelin
Quantum error correction compatible with continuous symmetries is a fundamental problem in quantum information and a possible route to robust analog quantum simulation. Because the…
Strategic Plan for Neutral Atom Quantum Computation
Adrian J. Menssen, Tout Wang, Michael Gullans +53
We present a strategic plan for neutral atom quantum computation, bringing together hardware development and theory advancements to achieve the goal of practical quantum advantage.…
Continuous Narrow-Linewidth Superradiance in Waveguide QED
Anna Bychek, Martin Fasser, Ivan Vybornyi +4
Superradiant lasers promise continuous, narrow-linewidth coherent emission at the bare atomic transition frequency, enabling frequency references of exceptional precision. Recent e…
Quantum simulation of gauge theories on dynamical spacetimes via Floquet-induced matrix models
Samuel Buckley-Bonanno, Noah Eckstein, Susanne F. Yelin
Quantum simulations of gauge theories are typically built on spatial lattices, an approach that has enabled major progress at the cost of requiring fixed background geometries and…
Learning Arbitrary Lindbladians with Quantum Error Correction
Nikita Romanov, Petr Ivashkov, Weiyuan Gong +4
We study ansatz-free Lindbladian learning, the problem of reconstructing the generator of an open quantum system without prior knowledge of its Hamiltonian or dissipator structures…
Entanglement and information scrambling in long-range measurement-only circuits
Abigail McClain Gomez, Fiona Abney-McPeek, Hong-Ye Hu +2
Measurement-only circuits provide a minimal setting in which repeated local projections can either generate or suppress many-body entanglement, giving rise to measurement-induced p…
Light-induced Self-Organization in Cooperative Free Space Atomic Arrays
Sara Molló-Guri, Oriol Rubies-Bigorda, Raphael Holzinger +2
We investigate how laser-driven, cooperative dipole-dipole interactions in weakly trapped atomic arrays give rise to self-organized configurations. Starting from an analytically tr…
Quantum theory for phonon lasing and non-classical state generation in mixed-species and single trapped ions
David Baur, Tanja Behrle, Ivan Rojkov +4
In this article we present a comprehensive theoretical investigation of phonon lasing with mixed-species trapped ions, as demonstrated in [T. Behrle, Phys. Rev. Lett. 131 (2023)],…
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…
Scalable Neural Decoders for Practical Fault-Tolerant Quantum Computation
Andi Gu, J. Pablo Bonilla Ataides, Mikhail D. Lukin +1
Quantum error correction (QEC) is essential for scalable quantum computing. However, it requires classical decoders that are fast and accurate enough to keep pace with quantum hard…
Ansatz-Free Learning of Lindbladian Dynamics In Situ
Petr Ivashkov, Nikita Romanov, Weiyuan Gong +3
Characterizing the dynamics of open quantum systems at the level of microscopic interactions and error mechanisms is essential for calibrating quantum hardware, designing robust si…
