A Variable Neighbourhood Descent Heuristic for Conformational Search Using a Quantum Annealer
D. J. J. Marchand, M. Noori, A. Roberts +6
Discovering the low-energy conformations of a molecule is of great interest to computational chemists, with applications in {\em in silico} materials design and drug discovery. In…
VanQver: The Variational and Adiabatically Navigated Quantum Eigensolver
Shunji Matsuura, Takeshi Yamazaki, Valentin Senicourt +2
The accelerated progress in manufacturing noisy intermediate-scale quantum (NISQ) computing hardware has opened the possibility of exploring its application in transforming approac…
Physics-Inspired Optimization for Quadratic Unconstrained Problems Using a Digital Annealer
Maliheh Aramon, Gili Rosenberg, Elisabetta Valiante +3
The Fujitsu Digital Annealer (DA) is designed to solve fully connected quadratic unconstrained binary optimization (QUBO) problems. It is implemented on application-specific CMOS h…
Uncertain fate of fair sampling in quantum annealing
Mario S. Könz, Guglielmo Mazzola, Andrew J. Ochoa +2
Recently, it was demonstrated both theoretically and experimentally on the D-Wave quantum annealer that transverse-field quantum annealing does not find all ground states with equa…
A small-world search for quantum speedup: How small-world interactions can lead to improved quantum annealer designs
Helmut G. Katzgraber, M. A. Novotny
There are many factors that influence the design of quantum annealing processing units. Here we address the issue of improving quantum annealing processing unit designs from the po…
Quantum control for high-fidelity multi-qubit gates
Raymond J. Spiteri, Marina Schmidt, Joydip Ghosh +2
Quantum control for error correction is critical for the practical use of quantum computers. We address quantum optimal control for single-shot multi-qubit gates by framing as a fe…
