Onset of scrambling as a dynamical transition in tunable-range quantum circuits
Sridevi Kuriyattil, Tomohiro Hashizume, Gregory Bentsen +1
In a fast scrambling many-body quantum system, information is spread and entanglement is built up on a timescale that grows logarithmically with the system size. This is of fundame…
Tunable Geometries in Sparse Clifford Circuits
Tomohiro Hashizume, Sridevi Kuriyattil, Andrew J. Daley +1
We investigate the emergence of different effective geometries in stochastic Clifford circuits with sparse coupling. By changing the probability distribution for choosing two-site…
Measurement-induced phase transitions in sparse nonlocal scramblers
Tomohiro Hashizume, Gregory Bentsen, Andrew J. Daley
Measurement-induced phase transitions arise due to a competition between the scrambling of quantum information in a many-body system and local measurements. In this work we investi…
Deterministic Fast Scrambling with Neutral Atom Arrays
Tomohiro Hashizume, Gregory Bentsen, Sebastian Weber +1
Fast scramblers are dynamical quantum systems that produce many-body entanglement on a timescale that grows logarithmically with the system size . We propose and investigate a f…
Treelike interactions and fast scrambling with cold atoms
Gregory Bentsen, Tomohiro Hashizume, Anton S. Buyskikh +4
We propose an experimentally realizable quantum spin model that exhibits fast scrambling, based on non-local interactions which couple sites whose separation is a power of 2. By co…
