    Graduate Explain delayed choice quantum eraser without consciousness

    I'm trying to understand the delayed choice quantum eraser experiment without consciousness. As I understand it, photons will either interfere or not depending on whether or not "which-path" information is randomly hidden and rendered unkowable to the experimenter. That is, rather the by any...

    Graduate Quantum Coherence - Decoherence Question

    So I understand that as the number of entangled particles increases, observable quantum mechanical properties decrease to the extent that the mass of particles collectively loses its wave-particle character and behaves classically. In other words, the particles' collective position-space...

    Graduate Entanglement Swapping Superluminal Communication

    I'm wondering whether or why quantum entanglement swapping or steering could or couldn't be used for superluminal communication. Below is a thought experiment. Setting aside the technological barriers do the laws of physics prevent this? On Earth Base Alpha: EPR Sources Entangle Numbered...
