Electronic silicon chips are approaching the physical thermal wall: resistance in copper wires generates heat that limits clock speeds and consumes enormous data center power.

Photonic Computing replaces electrons with photons traveling through silicon waveguides. By utilizing arrays of Mach-Zehnder interferometers (MZIs), optical processors perform matrix multiplications passively at the speed of light with near-zero energy consumption.
