“I must confess that I knew nothing about Micius; I had to buy myself a book,” smiles Nicolas Gisin, during the online press conference organized this Wednesday from China to announce this year’s winners. For our information, Micius was a Chinese philosopher from the 4th century BC to whom we owe, among other things, experiments on the propagation of light. Created in 2018, the Micius foundation intends to promote the pioneers of applications of quantum physics to telecommunications, computing, simulation and measuring instruments.

Many future applications are based on quantum entanglement, one of the strangest properties of very small physics: two particles prepared together – carefully –, for example two photons of light, behave as if they were a alone. They are entangled, like two lovers who remain linked regardless of the distance that separates them. Observing one particle immediately gives information about the other, even when we have sent them across the cosmos. Even Albert Einstein, one of the fathers of quantum physics, didn’t believe in it. We can even teleport the information carried by a particle of matter – but not the particle itself, let’s not exaggerate!
