Nonstabilizerness Estimation using Graph Neural Networks
Vincenzo Lipardi, Domenica Dibenedetto, Georgios Stamoulis +2
This article proposes a Graph Neural Network (GNN) approach to estimate nonstabilizerness in quantum circuits, measured by the stabilizer Rényi entropy (SRE). Nonstabilizerness is…
Quantum Checkers: The Development and Analysis of a Quantum Combinatorial Game
Marien Raat, Luuk van den Nouweland, Matthias Müller-Brockhausen +2
This paper develops and analyses a novel quantum combinatorial game: quantum checkers (codenamed Cheqqers). The concepts of superposition, entanglement, measurements and interferen…
Automated in situ optimization and disorder mitigation in a quantum device
Jacob Benestad, Torbjørn Rasmussen, Bertram Brovang +9
We investigate automated in situ optimization of the potential landscape in a quantum point contact device, using a gate array patterned atop the constriction. Optimiz…
A Monte Carlo Tree Search approach to QAOA: finding a needle in the haystack
Andoni Agirre, Evert Van Nieuwenburg, Matteo M. Wauters
The search for quantum algorithms to tackle classical combinatorial optimization problems has long been one of the most attractive yet challenging research topics in quantum comput…
Optimising entanglement distribution policies under classical communication constraints assisted by reinforcement learning
Jan Li, Tim Coopmans, Patrick Emonts +3
Quantum repeaters play a crucial role in the effective distribution of entanglement over long distances. The nearest-future type of quantum repeater requires two operations: entang…
