Quantum entanglement shows that reality can't be local
One thing I've never understood about interpretation of quantum entanglement experiments:<p>Based on what I've learned of these experiments, it seems to me that the least mind-bending interpretation is that the entanglement event results in two particles that have some complementary property k (i.e. one particle has k and the other has ~k) and which one of the two, k or ~k, is had by one of the particles is unknowable without collapsing the quantum state. However, both particles have the property from their inception, and so no faster-than-light or non-local interpretation should be needed. When the particles are separated to great distance and one is observed to collapse to k, the other must be observed to collapse to ~k because it was always a ~k particle.<p>Clearly, there's some aspect of the experiments that I don't understand that invalidates this simple interpretation, but I do not know what it is.
