Entangled Photons (original) (raw)

Entanglement is a key phenomenon in quantum mechanics that differs fundamentally from classical physics, offering unique applications for technology. This paper discusses experimental findings on the persistence of entanglement in the context of plasmon-assisted transmission of entangled photons. The study demonstrates how surface plasmons serve as mediators for transmitting entangled photons, examining how different configurations and focusing techniques affect the degree of polarization entanglement. Results indicate that while weakly-focused beams maintain polarization entanglement more consistently, high-intensity beams can degrade it, offering insights into the manipulation of entangled photons using surface plasmons.
