Dirac-1 is a low-power photonic EQC device purpose built for non-convex optimization. This room-temperature qubit computer is ideal for maximizing (or minimizing) binary objective functions. Similar to Ising machines, Dirac-1 works by finding the minimal ground state spin configuration (and energy) of a complex Hamiltonian with many inter-correlated variables.

The objective function which is optimized by Dirac-1 is of the form:
