On the QUBO formulation of Hamiltonian Cycle Problem

Amelia Durbec, Amina El Yaagoubi, Samuel Deleplanque

Combinatorial problems pose significant challenges, especially for large-scale instances. A promising approach to addressing these challenges involves quadratic unconstrained binary optimization (QUBO) models, a key framework in quantum computing. QUBO formulations require tailored approaches owing...

A hybrid column generation-based heuristic for solving the parallel machine scheduling problem with sequence-dependent set-up times

Luis Fernando Pérez Armas, Samuel Deleplanque, Riad Aggoune, Stefan Creemers

This study explores a hybrid quantum–classical algorithm for the parallel machine scheduling problem with sequence-dependent setup times, a key problem with applications across multiple industries. We propose a column-generation-based heuristic that combines a classical linear relaxation for the...

Scanning Microwave Microscopy of Quantum Materials with a Nano-Coaxial Probe

Sangjun Noh, Clément Lenoir, Mohamed Sebbache, Philip Hemmer, Hung-Ju Lin, Johannes Hoffmann, Kamel Haddadi, Peter Burke

We present a hybrid measurement platform that integrates super-resolution fluorescence microscopy with an open-ended nano-coaxial scanning microwave microscope (SMM). We demonstrate this system on diamond particles, which simultaneously emit bright fluorescence from nitrogen-vacancy (NV) centers....
