Understanding domain-wall encoding theoretically and experimentally
2021 · arXiv (Cornell University)
We analyze the method of encoding pairwise interactions of higher-than-binary discrete variables (these models are sometimes referred to as discrete quadratic models) into binary variables based on domain walls on one dimensional Ising chains. We …

Experimental demonstration of improved quantum optimization with linear Ising penalties
2024 · New Journal of Physics
Abstract The standard approach to encoding constraints in quantum optimization is the quadratic penalty method. Quadratic penalties introduce additional couplings and energy scales, which can be detrimental to the performance of a quantum optimizer. In …
