Quantum mechanics is full of subtle and unusual processes that challenge our common-sense understanding of the world, for instance simultaneous particle/wave behavior, quantum non-locality, quantum entanglement and instant quantum teleportation. Now, thanks to four Russian researchers in Moscow and Calgary, Canada, a new example of quantum weirdness has been added to the list, the peculiar phenomenon called Quantum Vampire Effect (QVE).
Ilya Fedorov, Alex Ulanov, Yury Kurochkin and Alex Lvovsky announced the discovery of the Quantum Vampire Effect in a recent ArXiv post. Here I will attempt a brief description of the four Russians' discovery.
