Ansätz Expressivity and Optimization in Variational Quantum Simulations of Transverse-field Ising Model Across System Sizes
Ashutosh P. Tripathi, Nilmani Mathur, Vikram Tripathi
The paper studies how well the Variational Quantum Eigensolver can find ground‑state properties, especially entanglement entropy, of the transverse‑field Ising model in 1‑D, 2‑D, a…

Optimization of the HHL Algorithm
Dhruv Sood, Nilmani Mathur, Vikram Tripathi
The Harrow-Hassidim-Lloyd (HHL) algorithm is a quantum algorithm for solving systems of linear equations that, in principle, offers an exponential improvement in scaling with the s…
