Marked vertex search on disordered graphs with Rosenzweig-Porter phases
Sabyasachi Chakraborty, Tilen Cadez, Sonjoy Majumder +1
Quantum marked vertex search algorithms are known to outperform their classical counterparts, yet their behavior in the presence of disorder remains largely unexplored. Here, we ad…
Quantum circuit model for continuous-time quantum walks on random graphs
Sabyasachi Chakraborty, Rohit Sarma Sarkar, Sonjoy Majumder +1
Quantum-circuit implementations of continuous-time quantum walks (CTQWs) can provide an efficient route to model graph-based algorithms. However, constructing circuits that faithfu…
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…
Note on Von Neumann Entropy and the Ordering of Inverse Temperatures
Rohit Kishan Ray
I show that for two inverse temperatures and , the von Neumann entropy of the Gibbs state for a given Hamiltonian satisfies $S(Ï_{β_1}) \geq S…
