3,280,999 | https://gr.inc/question/consider-a-quantum-system-consisting-of-two-photons-in-an-entangled-state-given | The coefficients $\sqrt{0.2}$ and $\sqrt{0.8}$ can be interpreted as probability amplitudes. The probabilities of measuring the photons in the horizontal or vertical polarization state are given by $p_H = |a_H|^2 = 0.2$ and $p_V = |a_V|^2 = 0.8$, respectively. Before measurement, the photons are in a superposition of both states, but due to the uneven weighting, it is more likely to measure them in the vertical polarization state. However, it's conceptually more accurate to describe the photons as being in a superposition of states rather than saying they are more in one state than the other before measurement. | null | Quantum Mechanics | CC-BY-NC-SA-4.0 | Meta/natural_reasoning | [
