From Einstein and Bell to Quantum Technologies: Quantum Non-locality in Action

Inselhalle

Main Hall

As pointed out by Einstein, and confirmed by the violation of Bell’s inequalities,
entanglement of separated particles is an extraordinary feature of quantum mechanics,
suggesting some kind of non-locality. It is now used in quantum technologies.
After recalling what are Bell’s inequalities and their experimental tests, I will show how the
notion of non-locality provides fruitful intuitions for some quantum communication
methods.
