Ground and excited-state energies with analytic errors and short time evolution on a quantum computer
Timothy Stroschein, Davide Castaldo, Markus Reiher
Accurately solving the Schrödinger equation remains a central challenge in computational physics, chemistry, and materials science. Here, we propose an alternative eigenvalue probl…
Utility-scale quantum computational chemistry
Davide Castaldo, Markus Reiher
Chemistry and materials science are widely regarded as potential killer application fields for quantum hardware. While the dream of unlocking unprecedented simulation capabilities…
Heisenberg limited multiple eigenvalue estimation via off-the-grid compressed sensing
Davide Castaldo, Stefano Corni
Quantum phase estimation is the flagship algorithm for quantum simulation on fault-tolerant quantum computers. We demonstrate that an \emph{off-grid} compressed sensing protocol, c…
A differentiable quantum phase estimation algorithm
Davide Castaldo, Soran Jahangiri, Agostino Migliore +2
The simulation of electronic properties is a pivotal issue in modern electronic structure theory, driving significant efforts over the past decades to develop protocols for computi…
