Precision quantum simulation of magnon spectra and interactions
Trond I. Andersen, Nikita Astrakhantsev, Jeronimo Martinez +329
Quantum simulation promises to advance materials discovery by accurately simulating complex states of matter, their microscopic excitations, and macroscopic response functions. The…
Multifractal and Glassy Signatures of Non-Ergodic 2D Quantum Dynamics
Aleksey Lunkin, Nicole S. Ticea, Michael T. Solomon +296
The fate of ergodicity and localization in disordered, interacting quantum systems in two spatial dimensions remains an outstanding open problem in non-equilibrium physics. Theoret…
Magic state cultivation on a superconducting quantum processor
Emma Rosenfeld, Craig Gidney, Gabrielle Roberts +292
Fault-tolerant quantum computing requires a universal gate set, but the necessary non-Clifford gates represent a significant resource cost for most quantum error correction archite…
Observation of disorder-induced superfluidity
Nicole Ticea, Elias Portoles, Eliott Rosenberg +298
The emergence of states with long-range correlations in a disordered landscape is rare, as disorder typically suppresses the particle mobility required for long-range coherence. Bu…
Reinforcement Learning Control of Quantum Error Correction
Volodymyr Sivak, Alexis Morvan, Michael Broughton +296
Quantum error correction (QEC) is the primary strategy for protecting a quantum computer from the environment. Its prerequisite is that errors must remain sufficiently rare, which…
Learning T-conjugated stabilizers: The multiple-squares dihedral StateHSP
Gideon Lee, Jonathan A. Gross, Masaya Fukami +1
The state hidden subgroup problem (StateHSP) is a recent generalization of the hidden subgroup problem. We present an algorithm that solves the non-abelian StateHSP over copies…
