Analysis
This paper investigates the performance of quantum annealing using spin-1 systems with a single-ion anisotropy term. It argues that this approach can lead to higher fidelity in finding the ground state compared to traditional spin-1/2 systems. The key is the ability to traverse the energy landscape more smoothly, lowering barriers and stabilizing the evolution, particularly beneficial for problems with ternary decision variables.
Key Takeaways
- •Spin-1 quantum annealing with anisotropy can improve ground state fidelity.
- •The intermediate spin level and tunable anisotropy facilitate smoother energy landscape traversal.
- •This approach is particularly advantageous for problems with ternary decision variables.
