Overview
Researchers from the Institut des NanoSciences de Paris, the Kastler Brossel Laboratory, and the University of Glasgow have developed a method that allows a scattering medium to become transparent specifically for information conveyed by entangled photon pairs. This transparency is selective; the same medium remains opaque to classical light.
Approach
The method developed utilizes entangled photon pairs to achieve selective transparency through a scattering medium. The scattering medium, which typically obstructs classical light, is rendered effectively transparent for the specific information carried by these entangled pairs. The described technique enables quantum information to traverse optical impediments that would otherwise block visual data when classical light is used.
Findings
- A scattering medium can be made selectively transparent for information carried by entangled photon pairs.
- The same scattering medium remains completely opaque to classical light.
- The developed method allows quantum information to pass through media that visually obstruct classical light.
