Polarization and holographic information become entangled in a quantum hologram. (IMAGE)
Caption
Polarization and holographic information become entangled in a quantum hologram. Holographic letters demonstrate entanglement through polarization of paired photons. By selecting different polarizer orientations for one photon, specific letters in the hologram could be selectively erased, demonstrating precise control over the entangled holographic information.
