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

called a transmission hologram, as it requires a laser light to illuminate the holographic film from behind to recreate the scene. This contrasts with a white light reflection hologram ...

Polarization and holographic information become entangled in a quantum hologram. Holographic letters demonstrate entanglement through polarization of paired photons. By selecting different ...

Meanwhile, metasurfaces—ultrathin optical devices—are known for their ability to encode vast amounts of information, allowing ...
