Semidefinite programming for understanding the limitations of Lindblad equations
Soumyadeep Sarma, Manas Kulkarni, Archak Purkayastha +1
Lindbladian quantum master equations (LEs) are the most popular descriptions for quantum systems weakly coupled to baths. But, recent works have established that in many situations…
Information phases of partial projected ensembles generated from random quantum states and scrambling dynamics
Alan Sherry, Saptarshi Mandal, Sthitadhi Roy
The projected ensemble -- an ensemble of pure states on a subsystem conditioned on projective measurement outcomes on its complement -- provides a finer probe of ergodicity and inf…
Quantum circuit model for continuous-time quantum walks on random graphs
Sabyasachi Chakraborty, Rohit Sarma Sarkar, Sonjoy Majumder +1
Quantum-circuit implementations of continuous-time quantum walks (CTQWs) can provide an efficient route to model graph-based algorithms. However, constructing circuits that faithfu…
Digital controllability of transverse field Ising chains
Vincenzo Roberto Arezzo, Ruiyi Wang, Kiran Thengil +2
Quantum Annealing (QA) encounters limitations when the energy gap along the annealing path becomes exponentially small, leading to impractically long runtimes. In contrast, the suc…
Partial projected ensembles and spatiotemporal structure of information scrambling
Saptarshi Mandal, Pieter W. Claeys, Sthitadhi Roy
Thermalisation and information scrambling in out-of-equilibrium quantum many-body systems are deeply intertwined: local subsystems dynamically approach thermal density matrices whi…
Do mixed states exhibit deep thermalisation?
Alan Sherry, Sthitadhi Roy
Deep thermalisation -- where ensembles of pure states on a local subsystem, conditioned on measurement outcomes on its complement, approach universal maximum-entropy ensembles -- r…
