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…
Speed limits to the growth of Krylov complexity in open quantum systems
Aranya Bhattacharya, Pingal Pratyush Nath, Himanshu Sahu
Recently, the propagation of information through quantum many-body systems, developed to study quantum chaos, have found many application from black holes to disordered spin system…
Krylov complexity for non-local spin chains
Aranya Bhattacharya, Pingal Pratyush Nath, Himanshu Sahu
Building upon recent research in spin systems with non-local interactions, this study investigates operator growth using the Krylov complexity in different non-local versions of th…
Quantum magnetometry using discrete-time quantum walk
Kunal Shukla, C. M. Chandrashekar
Quantum magnetometry uses quantum resources to measure magnetic fields with precision and accuracy that cannot be achieved by its classical counterparts. In this paper, we propose…
Complexity for one-dimensional discrete time quantum walk circuits
Aranya Bhattacharya, Himanshu Sahu, Ahmadullah Zahed +1
We compute the complexity for the mixed state density operator derived from a one-dimensional discrete-time quantum walk (DTQW). The complexity is computed using a two-qubit quantu…
Open system approach to Neutrino oscillations in a quantum walk framework
Himanshu Sahu, C. M. Chandrashekar
Quantum simulation provides a computationally-feasible approach to model and study many problems in chemistry, condensed-matter physics, or high-energy physics where quantum phenom…
