It's a quantum world

Quantum mechanics is real. It's spooky as hell, but it's real. Without its microscopically small probabilistic effects, we wouldn't have superconductors, lasers, and many forms of computing and cryptography. But despite our laboratory certainty, what's less clear is the role it plays in the fundamental nature of reality. And as a recent survey published by Anton Zeilinger at the University of Vienna has revealed, quantum physicists are still very divided on how it's to be interpreted.
