A bit too much: Reducing the bit width of Ising models for quantum annealing

Quantum annealers are devices that physically implement a quantum system called the 'Ising model' to solve combinatorial optimization problems. However, the coefficients of the Ising model often require a large bit width, making it difficult to implement physically. Now, scientists demonstrate a method to reduce the bit width of any Ising model, increasing the applicability and versatility of quantum annealers in many fields, including cryptography, logistics, and artificial intelligence.
