Diffraqtion
Diffraqtion is a Somerville, Massachusetts deeptech company building what it calls the first quantum camera for satellites and telescopes. Spun out of research at MIT and the University of Maryland, its photon-counting sensors paired with AI aim to extract far more information from incoming light than conventional CMOS or CCD sensors, letting smaller, cheaper optics see beyond the diffraction limit. The company targets space domain awareness, defense, and Earth observation, and raised $4.2M in pre-seed funding in January 2026 alongside a DARPA SBIR contract.
Zaijun Chen
Zaijun Chen is a physicist-turned-founder building light-powered computers for artificial intelligence. As co-founder and CEO of Opticore, he is developing photonic optical processing units (OPUs) that the company says are up to 100x more energy efficient and 25x denser than leading GPUs. Trained at the Max Planck Institute of Quantum Optics and MIT, and now director of the Laboratory of Intelligent and Quantum Photonics at USC, Chen turned a decade of precision-optics research into a venture-backed bet that the future of AI compute runs on photons instead of electrons.
