Efficient targeting of arbitrary excited states with quantum inverse power iteration through filtering polynomials
Srushti Patil, Nina Glaser
In this work, we introduce a quantum inverse power iteration (QIPI) algorithm based on the quantum singular value transformation (QSVT) to target arbitrary excited states. Given an…

The PPP model - a minimal viable parametrisation of conjugated chemistry for modern computing applications
Marcel David Fabian, Nina Glaser, Gemma C. Solomon
The semi-empirical Pariser-Parr-Pople (PPP) Hamiltonian is reviewed for its ability to provide a minimal model of the chemistry of conjugated -electron systems, and its current…

Quantum block Krylov subspace projector algorithm for computing low-lying eigenenergies
Maria Gabriela Jordão Oliveira, Nina Glaser
Computing eigenvalues is a computationally intensive task central to numerous applications in the natural sciences. Toward this end, we investigate the quantum block Krylov subspac…
