Researchers from the Institut des NanoSciences de Paris, the Kastler Brossel Laboratory and the University of Glasgow have developed an innovative method that renders a scattering medium transparent solely for information carried by entangled photon pairs, while the same medium remains completely opaque to classical light.
Advances in quantum optics and photon entanglement research have reached a point where practical applications for quantum communication and sensing are beginning to emerge from theoretical concepts.
This breakthrough provides a pathway for secure, stealth communication and imaging through previously impenetrable environments, opening new possibilities for defense, subsea, and atmospheric applications.
The ability to send information through chaotic scattering media using entangled photons fundamentally changes the limitations of line-of-sight communication and sensing.
