Graph-State Circuit Blocks control Entanglement and Scrambling Velocities
Chandana Rao, Himanshu Sahu, Aranya Bhattacharya +3
Random circuit models often describe local dynamics using generic two-qubit gates, which have proven successful in capturing entanglement growth and operator spreading in many cont…
Quantum chaos in PT symmetric quantum systems
Kshitij Sharma, Himanshu Sahu, Subroto Mukerjee
In this study, we explore the interplay between -symmetry and quantum chaos in a non-Hermitian dynamical system. We consider an extension of the standard diagnostics…
Information scrambling and entanglement dynamics in Floquet Time Crystals
Himanshu Sahu, Fernando Iemini
We study the dynamics of out-of-time-ordered correlators (OTOCs) and entanglement of entropy as quantitative measures of information propagation in disordered many-body systems exh…
Information scrambling in quantum walks: Discrete-time formulation of Krylov complexity
Himanshu Sahu
We study information scrambling -- a spread of initially localized quantum information into the system's many degree of freedom -- in discrete-time quantum walks. We consider out-o…
