Local autonomous inference machines for quantum LDPC codes
Siddhant Midha, Dmitry A. Abanin
We introduce a local and distributed framework for decoding quantum LDPC codes. Built atop belief propagation (BP), the architecture combines strictly local processing of syndrome…
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…
Algorithmic Locality via Provable Convergence in Quantum Tensor Networks
Siddhant Midha, Yifan F. Zhang, Daniel Malz +2
Belief propagation has recently emerged as a powerful framework for evaluating tensor networks in higher dimensions, combining computational efficiency with provable analytical gua…
Simple slow operators and quantum thermalization
Tian-Hua Yang, Sarang Gopalakrishnan, Ethan Jeon +1
We establish a rigorous operator-space condition for the thermalization of typical initial states. We introduce a concept of simple slow operators (SSOs), defined as operators that…
Belief Propagation and Tensor Network Expansions for Many-Body Quantum Systems: Rigorous Results and Fundamental Limits
Siddhant Midha, Grace M. Sommers, Joseph Tindall +1
Belief propagation (BP) provides a scalable heuristic for contracting tensor networks on loopy graphs, but its success in quantum many-body settings has largely rested on empirical…
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…
