A case study of variational quantum algorithms for a job shop scheduling problem
David Amaro, Matthias Rosenkranz, Nathan Fitzpatrick +2
Combinatorial optimization models a vast range of industrial processes aiming at improving their efficiency. In general, solving this type of problem exactly is computationally int…
Reducing Unitary Coupled Cluster Circuit Depth by Classical Stochastic Amplitude Pre-Screening
Maria-Andreea Filip, Nathan Fitzpatrick, David Muñoz Ramo +1
Unitary Coupled Cluster (UCC) approaches are an appealing route to utilising quantum hardware to perform quantum chemistry calculations, as quantum computers can in principle perfo…
Evaluating low-depth quantum algorithms for time evolution on fermion-boson systems
Nathan Fitzpatrick, Harriet Apel, David Muñoz Ramo
Simulating time evolution of quantum systems is one of the most promising applications of quantum computing and also appears as a subroutine in many applications such as Green's fu…
Molecular Excited State Calculations with Adaptive Wavefunctions on a Quantum Eigensolver Emulation: Reducing Circuit Depth and Separating Spin States
Hans Hon Sang Chan, Nathan Fitzpatrick, Javier Segarra-Marti +2
Ab initio electronic excited state calculations are necessary for the quantitative study of photochemical reactions, but their accurate computation on classical computers is plague…
