Quantum Entanglement and Young’s Experiment

Bohm’s variation of the Einstein-Podolsky-Rosen thought experiment may reveal the path a photon travels in Young’s experiment without causing the interference pattern to disappear. Unlike in Young’s original experiment, this hypothetical scenario involves entangled photons incident on a screen with two closely spaced narrow slits. To address the challenge of simultaneously observing both the wave and particle nature of light without violating Heisenberg’s position-momentum uncertainty principle, an apparatus that relies on the conservation of linear momentum and quantum entanglement is constructed to indirectly observe the path traveled by the entangled photons while preserving their quantum superposition. This thought experiment effectively uncovers the complex mystery surrounding the wave-particle duality inherent in quantum phenomena.
