Quantum experiment dissects wave-particle mash-up
Light shows dual nature simultaneously in modified delayed-choice apparatus
A new experiment captures a single parcel of light morphing between wave and particle.
Published in the April Physical Review A, the experiment dissects a light pulse associated with a single photon to expose wavelike and particle-like components. The results add to recent evidence suggesting that just as Schrödinger’s cat can be dead and alive at the same time, light can be a particle and a wave simultaneously at the quantum level.
