(Phys.org) A photonic chip with no less than 128 tunable components proves to be a true computing “Swiss army knife” with a variety of applications. During her research on measuring light wavelengths using this photonic chip, Caterina Taballione of the University of Twente came across yet another application serendipitously—by sending single photons through the system instead of continuous light, the optical components can perform quantum operations, as well. The same chip works as a photonic quantum processor.
The UT scientists involved therefore founded a new company called QuiX, to make the chip widely available for other scientists and R&D departments.
