Quantum physics and plant biology seem like two branches of science that could not be more different, but surprisingly they may in fact be intimately tied. Scientists have discovered an unusual quantum effect in the earliest stages of photosynthesis.
'Quantum magic' without any 'spooky action at a distance'
Quantum channel made of light - ETH Zurich - Using ultracold atoms and laser light, researchers measured a stepwise change in conductivity as the atoms pass through tiny structures, the first time this quantum effect has been observed for electrically neutral particles.

The researchers think they have created majorana fermions, which have identical antiparticles but which don't annihilate each other, at the ends of a nanowire device, shown here with orange balls. CREDIT: TU Delft
