Rydberg-Blockade-Based Parity Quantum Optimization

Phys Rev Lett. 2023 Jun 2;130(22):220601. doi: 10.1103/PhysRevLett.130.220601.

Abstract

We present a scalable architecture for solving higher-order constrained binary optimization (HCBO) problems on current neutral-atom hardware operating in the Rydberg blockade regime. In particular, we formulate the recently developed parity encoding of arbitrary connected HCBO problems as a maximum-weight independent set (MWIS) problem on disk graphs, that are directly encodable on such devices. Our architecture builds from small MWIS modules in a problem-independent way, crucial for practical scalability.
