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…
Quantum simulation of nanographenes and Trotter error cancellation
Andreas Juul Bay-Smidt, Nina Glaser, Marcel D. Fabian +3
Fault-tolerant quantum computing is a promising tool for simulating molecules and materials, but frequently-considered applications require substantial resources, and the gap betwe…
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…
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…
