A quantum wire approach to weighted combinatorial graph optimisation problems
André G. de Oliveira, André G. de Oliveira, Johannes Kombe +7
Neutral atom arrays provide a versatile platform to implement coherent quantum annealing as an approach to solving hard combinatorial optimization problems. Here we present and exp…
Reducibility of native weighted graphs on Rydberg Arrays
J. Kombe, J. D. Pritchard
We investigate the classical reducibility of random unit-disk graph (UDG) instances of the maximum independent set (MIS) and maximum weighted independent set (MWIS) problems, which…
Entangled states from sparsely coupled spins for metrology with neutral atoms
Sridevi Kuriyattil, Pablo M. Poggi, Jonathan D. Pritchard +2
Quantum states featuring extensive multipartite entanglement are a resource for quantum-enhanced metrology, with sensitivity up to the Heisenberg limit. However, robust generation…
Engineered Chirality of One-Dimensional Nanowires
Megan Briggeman, Elliott Mansfield, Johannes Kombe +11
The origin and function of chirality in DNA, proteins, and other building blocks of life represent a central question in biology. Observations of spin polarization and magnetizatio…
Can multipartite entanglement be characterized by two-point connected correlation functions ?
Luca Lepori, Andrea Trombettoni, Domenico Giuliano +5
We discuss under which conditions multipartite entanglement in mixed quantum states can be characterized only in terms of two-point connected correlation functions, as it is the ca…
