Scientists Unveil Breakthrough in Quantum Entanglement

Speedy Summary

• Physicists at Technion – Israel Institute of Technology observed a new form of quantum entanglement using the total angular momentum of photons confined in nanoscale structures.
• This finding potentially enables on-chip quantum data processing by encoding information in the total angular momentum property of photons.
• Angular momentum is divided into spin (related to photon electric field rotation) and orbit (linked to rotational motion in space). When confined to nanoscale structures smaller than their wavelength, these properties merge into a single quantity: total angular momentum.
• Miniaturization enhances photon-material interaction while enabling compact devices akin to miniaturized electronic circuits. It also facilitates novel phenomena not achievable at normal dimensions.
• Researchers mapped photon states within nanoscale systems, entangled them via unique properties tied to their size, and confirmed quantum entanglement between pairs.
• This research marks the first discovery of new quantum entanglement properties in over 20 years, potentially paving the way for advanced developments in photon-based quantum interaction and computing components.
