Researchers Control Photon Behaviour Via Dual Choices

By controlling both input and output beam splitters within a Mach-Zehnder interferometer, scientists observe wave-particle behaviour using entangled photons. The implementation of Wheeler’s delayed-choice experiment with dual selections enables manipulation of these two beam splitters simultaneously; revealing how single photons behave under different configurations. An entangled state, described as a combination of zero and one for each qubit, utilises this level of control over the photonic system. A fundamental physics experiment demonstrates that photons exhibit both wave and particle characteristics depending on…
