Performance of Domain-Wall Encoding for Quantum Annealing

Understand

In this paper we experimentally test the performance of the recently proposed domain-wall encoding of discrete variables from [Chancellor Quantum Sci.

• Technol.
• 4 045004] on Ising model flux qubit quantum annealers.
• We compare this encoding with the traditional one-hot methods and find that they outperform the one-hot encoding for three different problems at different sizes both of the problem and of the variables.
