Long-lived memory in sliding spin chains
Charles Stahl, Ethan Lake
The paper investigates how sliding two ferromagnetic one‑dimensional Ising chains past each other creates magnetic friction that dramatically lengthens the time the system remember…
Brownian ratchets and pumps universally simulate many-body active dynamics
Charles Stahl, Ethan Lake, Vedika Khemani
Active systems can exhibit a broad range of phenomena forbidden in equilibrium. Their dynamics are often specified by abstract local update rules, and it is generally unclear when…
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…
Proof of a finite threshold for the union-find decoder
Satoshi Yoshida, Ethan Lake, Hayata Yamasaki
Fast decoders that achieve strong error suppression are essential for fault-tolerant quantum computation (FTQC) from both practical and theoretical perspectives. The union-find (UF…
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…
