Scalable nuclear shell model calculations on noisy quantum computers
Durgesh Pandey, Ankit Kumar Das, P. Arumugam
The exact diagonalization of the nuclear shell model scales exponentially, leading to severe memory bottlenecks in classical high-performance computing (HPC). While hybrid quantum…
Quantum Simulation of Nuclear Shell Model Using GCM-Based Methods on NISQ Devices
Durgesh Pandey, Ashutosh Singh, Ankit Kumar Das +1
Based on the Generator Coordinate Method (GCM), we use a Quantum GCM (QuGCM) within a hybrid quantum-classical framework to simulate low-lying eigenstates of nuclear systems on qua…
Quantum computing-based solver for interacting power grids
Ankit Kumar Das, Durgesh Pandey, P. Arumugam
The proliferation of power electronics in multi-terminal transmission grids has increasingly led to harmonic distortions and dynamic instabilities. While Resonance Mode Analysis (R…
Real Variance-Based Variational Quantum Eigensolver for Non-Hermitian Matrices
Durgesh Pandey, Ankit Kumar Das, P. Arumugam
Non-Hermitian operators naturally arise in the description of open quantum systems, which exhibit features such as resonances and decay processes, where the associated eigenvalues…
Tagged particle dynamics in supercooled quantum liquid
Ankita Das, Gopika Krishnan, Eran Rabani +1
We analyze dynamics of quantum supercooled liquids in terms of tagged particle dynamics. Unlike the classical case, uncertainty in the position of a particle in quantum liquid lead…
