Symmetry Constraints Regularize Neural Quantum State Learning
Turbasu Chatterjee, Manas Sajjan, Songbo Xie +4
Neural quantum states (NQS) offer highly expressive variational wavefunctions, but their optimization is frequently bottlenecked by redundant parameters and poorly conditioned land…
Energy Landscape Structure of Small Graph Isomorphism Under Variational Optimization
Turbasu Chatterjee, Shah Ishmam Mohtashim, Akash Kundu
We investigate a quadratic unconstrained binary optimization (QUBO) formulation of the graph isomorphism problem using the Quantum Approximate Optimization Algorithm (QAOA) and the…
Modified security analysis of device-independent quantum key distribution with random key basis
Sawan Bhattacharyya, Turbasu Chatterjee, Pankaj Agrawal +1
Security analysis is a critical part in any cryptographic protocol, may it be classical or quantum. Without security analysis, one cannot ensure the secrecy of the distributed keys…
A near-term quantum simulation of the transverse field Ising model hints at Glassy Dynamics
Shah Ishmam Mohtashim, Arnav Das, Turbasu Chatterjee +1
We demonstrate quantum circuit simulations of the transverse field Ising model with longitudinal fields, displaying salient features of glassy dynamics. The energy landscape and sp…
