Quantum Uncertainty vs. Universal Properties of Particles

    If we have two electrons. Now put each one of them in a separate identical box and observe their properties, and collect as much information as possible, would you have obtain an identical result?

    If you do the same experiment in each of the boxes you should get the same results, within the limits of experimental error.

    What you cannot do is measure the position or energy of the particle in one box and the momentum or duration in the other, and then claim to have evaded the uncertainty principle. If the particles experience different measurements they will no longer be considered identical.

    Does this mean that the two electrons are entangled?

    Certainly not. It just means QM is consistent. I am here assuming an experiment where the eigenvalues are degenerate, so the observable has a definite value. If you have many eigenvaues the different boxes could show different results. But there is no link between the boxes.
