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 and complexity from string scattering amplitudes
Aranya Bhattacharya, Aneek Jana
We introduce Krylov spread complexity in the context of black hole scattering by studying highly excited string states (HESS). Krylov complexity characterizes chaos by quantifying…

Spread complexity and localization in -symmetric systems
Aranya Bhattacharya, Rathindra Nath Das, Bidyut Dey +1
We present a framework for investigating wave function spreading in -symmetric quantum systems using spread complexity and spread entropy. We consider a tight-binding…
