Recently, the scientists from S.N. Bose National Centre for Basic Sciences (SNBNCBS), Kolkata have developed a novel protocol to find out whether a pair of electrons is in an entangled state.
This novel protocol to measure the status of entanglement is known as Device Independent Self-Testing (DIST) method.
Quantum Entanglement is the physical phenomenon that occurs when a pair or group of particles is generated and they interact in such a way that the quantum state of each particle of the pair or group cannot be described independently of the state of the others.
