In a study published in the journal Nature, the Technion researchers, led by Ph.D. student Amit Kam and Dr. Shai Tsesses, discovered that it is possible to entangle photons in nanoscale systems that are a thousandth the size of a hair, but the entanglement is not carried out by the conventional properties of the photon, such as spin or trajectory, but only by the total angular momentum.
This is the first discovery of a new quantum entanglement in more than 20 years, and it may lead in the future to the development of new tools for the design of photon-based quantum communication and computing components, as well as to their significant miniaturization.
