This is a narrow constriction in a ring of superconductor. Current can only move around the ring because of quantum laws; the apparatus provides a neat way to investigate the properties of quantum mechanics and is a technology to build qubits for quantum computers.

What does it mean to exist in a superposition of states? Does quantum fuzziness spill over to our macroscopic domain? Is experienced reality inherently probabilistic or does the universe split in two every time we make a choice? An experimental study.
Harry Lagoussis is a filmmaker and cartoonist based in Athens, Greece. He has been a science geek ever since he read Stephen Hawking's A Brief History of Time as a teenager. This film was inspired by quantum weirdness, silent-era comedy films, consumer-video aesthetics and his cat allergy. You can find out more about his work at www.harrylagoussis.gr.
