A Study of Entanglement and Ansatz Expressivity for the Transverse-Field Ising Model using Variational Quantum Eigensolver
Ashutosh P. Tripathi, Nilmani Mathur, Vikram Tripathi
The Variational Quantum Eigensolver (VQE) is a leading hybrid quantum-classical algorithm for simulating many-body systems in the NISQ era. Its effectiveness, however, depends on t…

Inequivalence between the Euclidean and Lorentzian versions of the type IIB matrix model from Lefschetz thimble calculations
Chien-Yu Chou, Jun Nishimura, Ashutosh Tripathi
The type IIB matrix model is conjectured to describe superstring theory nonperturbatively in terms of ten bosonic traceless Hermitian matrices ($μ=0, \ldots ,…
