Quantum entanglement, one of the strangest and most powerful aspects of physics, has just been taken to a new level with the use of metasurfaces.

Researchers have discovered a way to create quantum holograms, where entangled photons encode intricate information with unprecedented precision. By leveraging the properties of metasurfaces, they demonstrated control over entangled holographic letters, opening doors to secure quantum communication and even anti-counterfeiting technology.
