TEHRAN (ANA)- Quantum entanglement was directly observed and recorded at the macroscopic scale – a scale much bigger than the subatomic particles normally associated with entanglement, showed a study conducted at the National Institute of Standards and Technology (NIST) in the US.

TEHRAN (ANA)- Researchers from the Max Planck Institute of Quantum Optics in Germany successfully entangled 14 photons into a state considered optimal for qubits, more than doubling previous attempts – while also improving on their efficiency.
