Abstract
A system employs a plurality of physical qubits, each having a respective bias operable to up to six differentiable inputs to solve a Quadratic Unconstrained Binary Optimization problem. Some physical qubit couplers are operated as intra-logical qubit couplers to ferromagnetically couple respective pairs of the physical qubits as a logical qubit, where each logical qubit represents a variable from the Quadratic Unconstrained Binary Optimization problem. The logical qubits may include two or more physical qubits.
