Measurement-induced phase transitions in quantum inference problems and quantum hidden Markov models
Sun Woo P. Kim, Curt von Keyserlingk, Austen Lamacraft
Recently, there is interest in coincident 'sharpening' and 'learnability' transitions in monitored quantum systems. In the latter, an outside observer's ability to infer properties…

Emergent random matrix universality in quantum operator dynamics
Oliver Lunt, Thomas Kriecherbauer, Kenneth T-R McLaughlin +1
The high complexity of many-body quantum dynamics means that essentially all approaches either exploit special structure or are approximate in nature. One such approach--the memory…
