Quantum computer-based simulation of Stark many-body localization in a 1D Fermi-Hubbard model
Abdul Kalam, Prasenjit Deb, Akitada Sakurai +3
Many-body localization (MBL) is a dynamical phenomenon that describes the non-ergodicity of isolated quantum many-body systems. In contrast to thermalization, this phenomenon leads…
Better accuracy with fewer qubits: Single-particle basis set optimization for quantum chemistry on quantum computers
Subimal Deb, V. S. Prasannaa
In spite of recent advances, quantum computers are expected to be sufficiently noisy in the coming few years to the extent of limiting quantum chemical calculations to relatively s…
Resource-efficient quantum-selected configuration interaction for molecular properties
Suprava Sahoo, Abdul Kalam, Kenji Sugisaki +2
The quantum-selected configuration interaction identifies important determinantal basis functions through real-time evolution of a reference wavefunction and diagonalizing the Hami…
Quantum linear solvers for quantum chemistry: prospects of exponential quantum advantage
Peniel Bertrand Tsemo, Kenji Sugisaki, Ishita Bhattacharjee +1
Quantum linear solvers (QLSs) can offer the potential for exponential quantum advantage in solving quantum chemical problems, but its assessment hinges on determining the condition…
The Harrow-Hassidim-Lloyd algorithm with qutrits
Tushti Patel, V. S. Prasannaa
We extend the Harrow-Hassidim-Lloyd (HHL) algorithm, which is well-studied in the qubit framework, to its qutrit counterpart (which we call qutrit HHL, as opposed to qubit HHL, whi…
Do quantum linear solvers offer advantage for networks-based system of linear equations?
Disha Shetty, Supriyo Dutta, Palak Chawla +5
In this exploratory numerical study, we assess the suitability of Quantum Linear Solvers(QLSs)toward providing a quantum advantage for Networks-based Linear System Problems (NLSPs)…
