Quantum-circuit implementations of continuous-time quantum walks (CTQWs) can provide an efficient route to model graph-based algorithms. However, constructing circuits that faithfu…
Blockwise Optimization for Projective Variational Quantum Dynamics (BLOP-VQD): Algorithm and Implementation for Lattice Systems
Harshdeep Singh, Sonjoy Majumder, Sabyashachi Mishra
We present an efficient approach to simulate real-time quantum dynamics using Projected Variational Quantum Dynamics (PVQD), where the computational cost is reduced by strategicall…
Scalable quantum circuit simulation of a chaotic Ising chain
Sabyasachi Chakraborty, Rohit Sarma Sarkar, Sonjoy Majumder
The recent advancements in out-of-time-ordered correlator (OTOC) measurements have provided a promising pathway to explore quantum chaos and information scrambling. However, despit…
Dissipation in fermionic two-body continuous-time quantum walk under the steepest entropy ascent formalism
Rohit Kishan Ray, R. Srikanth, Sonjoy Majumder
Quantum walks play a crucial role in quantum algorithms and computational problems. Many-body quantum walks can reveal and exploit quantum correlations that are unavailable for sin…
