Evaluating quantum circuits in the reservoir computing paradigm
Gaurav Rudra Malik, Amit Kumar Jaiswal, S. Aravinda +1
Reservoir computing is a framework which is primarily used for temporal information processing, using the intrinsic dynamics of an underlying physical system. The framework, in a q…
Krylov complexity in ergodically constrained nonintegrable transverse-field Ising model
Gaurav Rudra Malik, Jeet Sharma, Rohit Kumar Shukla +2
The nonintegrable transverse-field Ising model is a common platform for studying ergodic quantum dynamics. In this work, we introduce a simple variant of the model in which this er…
Entanglement structure for finite system under dual-unitary dynamics
Gaurav Rudra Malik, Rohit Kumar Shukla, Sudhanva Joshi +2
The dynamics of quantum many-body systems in the chaotic regime are of particular interest due to the associated phenomena of information scrambling and entanglement generation wit…
Characterizing quantum dynamics using multipartite entanglement generation
Gaurav Rudra Malik, Rohit Kumar Shukla, S. Aravinda +1
Entanglement is a defining feature of many-body quantum systems and is an essential requirement for quantum computing. It is therefore useful to study physical processes which gene…
Diagnosing chaos in a periodically driven Ising model with a ramping field via out-of-time-order correlation saturation
Rohit Kumar Shukla, Gaurav Rudra Malik, S. Aravinda +1
The dynamic region of out-of-time-ordered correlators (OTOCs) serves as a powerful indicator of chaos in classical and semiclassical systems, capturing the characteristic exponenti…
