Multi-Particle Quantum Walks in a Dipole-Conserving Bose-Hubbard Model
Sooshin Kim, Byungmin Kang, Perrin Segura +4
When particles move through a crystal or optical lattice, their motion can sometimes become frozen by strong external forces -- yet collective motion may still emerge through subtl…
Local active error correction from simulated confinement
Ethan Lake
We refine an old idea for performing fault-tolerant error correction in topological codes by simulating confining interactions between excitations. We implement confinement using a…
Exploring the Landscape of Non-Equilibrium Memories with Neural Cellular Automata
Ehsan Pajouheshgar, Aditya Bhardwaj, Nathaniel Selub +1
We investigate the landscape of many-body memories: families of local non-equilibrium dynamics that retain information about their initial conditions for thermodynamically long tim…
Squeezing codes: robust fluctuation-stabilized memories
Ethan Lake, Sunghan Ro
We introduce families of classical stochastic dynamics in two and higher dimensions which stabilize order in the absence of any symmetry. Our dynamics are qualitatively distinct fr…
Fast offline decoding with local message-passing automata
Ethan Lake
We present a local offline decoder for topological codes that operates according to a parallelized message-passing framework. The decoder works by passing messages between anyons,…
