Improved spectral gaps for random quantum circuits: large local dimensions and all-to-all interactions
Jonas Haferkamp, Nicholas Hunter-Jones
Random quantum circuits are a central concept in quantum information theory with applications ranging from demonstrations of quantum computational advantage to descriptions of scra…
Fluctuations of subsystem entropies at late times
Jordan Cotler, Nicholas Hunter-Jones, Daniel Ranard
We study the fluctuations of subsystem entropies in closed quantum many-body systems after thermalization. Using a combination of analytics and numerics for both random quantum cir…
Random quantum circuits anti-concentrate in log depth
Alexander M. Dalzell, Nicholas Hunter-Jones, Fernando G. S. L. Brandão
We consider quantum circuits consisting of randomly chosen two-local gates and study the number of gates needed for the distribution over measurement outcomes for typical circuit i…
