Single photon reveals quantum entanglement of 16 million atoms: Researchers have demonstrated the entanglement between 16 million atoms in a crystal crossed by a single photon, confirming the theory b


Université de Genève


Scientists at the University of Geneva (UNIGE), Switzerland, recently reengineered their data processing, demonstrating that 16 million atoms were entangled in a one-centimetre crystal. Imagine a physicist who always wears two socks of different colours. There is a correlation, in other words, between the two socks. Each scientist has a quantum particle, a photon, for example. They will find that the polarisation of the photons is always opposite (as with the socks in the above example), and that the photon has no intrinsic polarisation.
