Hey,

Does anyone know a link to a paper talking about the experimental verification of indistinguishability of some free particles? For example showing it for free neutrons or something.

Thanks!

I think there is indirect evidence, namely that indistinguishablitity is built-in in the Fock-space construction, that this implies a certain state-counting and statistics (Fermi-Dirac or Bose-Einstein instead of Boltzmann) and that all results derived from it agree with nature.
 
Look for Coulomb or Mott scattering in quantum-mechanics textbooks. If it's a good book, they show the scattering of nuclei that are (a) distinguishable, (b) fermions, and (c) bosons. There you see a huge difference in the various (differential) cross sections due to Pauli blocking and Bose enhancement, compared to the case of distinguishable particles.

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
According to recent podcast between Jacob Barandes and Sean Carroll, Barandes claims that putting a sensitive qubit near one of the slits of a double slit interference experiment is sufficient to break the interference pattern. Here are his words from the official transcript: Is that true? Caveats I see: The qubit is a quantum object, so if the particle was in a superposition of up and down, the qubit can be in a superposition too. Measuring the qubit in an orthogonal direction might...
