Photon Entanglement over the Fiber-Optic Network

by: Misha Brodsky, January 10, 2011

Quantum entanglement—where two particles belong to one state and thus act in concert even when separated over a vast distance—may yield unconditionally secure cryptographic systems, something not feasible today.

But will an entangled quantum state survive over the fiber-optic network?

Experiments being conducted at AT&T Research are starting to reveal answers, and helping scientists and engineers take the next steps toward harnessing quantum powers for real-world applications.  Read more
