QCi Dirac 2

Dirac-2 is a low-power, room temperature, photonic EQC device purpose built for integer and non-convex optimization that uses qudits (quantum digits) instead of qubits as variables. Dirac-2 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-2 is of the form:

Dirac-1 equation
