Quantum isomer search.

PLoS ONE, 2020
Isomer search or molecule enumeration refers to the problem of finding all the isomers for a given molecule. Many classical search methods have been developed in order to tackle this problem.

HPC: A Computational Benchmark of Classical, Parallel, and Hybrid Metaheuristics for QUBO-Based Suspension Geometry Optimization

Machines
The calibration of suspension geometry involves highly nonlinear kinematic relationships and leads to challenging optimization landscapes that are difficult to explore efficiently with classical local methods. Quadratic Unconstrained Binary Optimization (

Track clustering with a quantum annealer for primary vertex reconstruction at hadron colliders

, 2020
Clustering of charged particle tracks along the beam axis is the first step in reconstructing the positions of hadronic interactions, also known as primary vertices, at hadron collider experiments.

A Simple QUBO Formulation of Sudoku

Proceedings of the Genetic and Evolutionary Computation Conference Companion
This article describes how to solve Sudoku puzzles using Quadratic Unconstrained Binary Optimization (QUBO). To this end, a QUBO instance with 729 variables is constructed, encoding a Sudoku grid with all constraints in place, which is then partially assigned to account for clues.

Quantum computer based feature selection in machine learning

IET Quantum Communication
The problem of selecting an appropriate number of features in supervised learning problems is investigated. Starting with common methods in machine learning, the feature selection task is treated as a quadratic unconstrained optimisation problem (QUBO ...

Partitioning QUBO with two-way one-hot conditions on traveling salesman problems for city distributions with multiple clusters

Frontiers in Computer Science
We introduce a method for solving a quadratic unconstrained binary optimization (QUBO) with the two-way one-hot constraints by dividing the QUBO into parts and solving it with an Ising machine.

Hybrid subQUBO Annealing With a Correction Process for Multi-Day Intermodal Trip Planning

IEEE Access
The multi-day intermodal trip planning problem (MITPP) is an optimization problem that seeks to create the optimal route to visit Point-of-Interest (POI) and hotels over days. This problem involves coordinating intermodal transportation, such as walking,
