New Quantum Entanglement Discovered: Nanoscale Photons Hold Key to Future Tech

Researchers at Technion in Israel have discovered a new type of quantum entanglement. This entanglement involves the total angular momentum of photons within nanoscale structures. Published in Nature, this breakthrough could transform quantum communication and computing.

Quantum entanglement links the states of two particles, regardless of distance. Einstein called it "spooky action at a distance." This phenomenon is a cornerstone of quantum technologies. The 2022 Nobel Prize in Physics highlighted its importance for quantum computing and communication.

Led by Amit Kam and Dr. Shai Tsesses, the Technion team demonstrated entanglement using the total angular momentum of photons. This occurs in nanoscale systems, a thousandth the size of a human hair. This miniaturization could lead to more compact quantum devices.

The researchers mapped the states of photons as they moved through the nanoscale system. They verified entanglement between photon pairs based on their unique properties. This discovery opens doors for advanced, compact quantum communication and computing components.
