Floquet-Based Ising Machines Escape Local Minima in QUBO Problems

Physical Review X
Solving large-scale quadratic unconstrained binary optimization (QUBO) problems is critical in various fields, including physics, finance, and engineering. However, these problems remain intractable on conventional computing architectures.

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.

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 ...

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,
