India, Sept. 20 -- Physicists at the University of Oxford have helped confirm that one of the strangest phenomena in physics - quantum entanglement - occurs even among some of the heaviest and most fleeting particles ever created. The discovery, made using the world's most powerful particle collider at CERN, has been published today in Physical Review Letters.

Entanglement is the phenomenon in which two particles from the same origin remain connected, even if they move far apart in time and space. If something affects one particle, it will also affect all the particles with which it is entangled. This means that measuring a property of one particle instantly tells you something about its entangled partner/s, no matter how distant they ar...
