> That doesn't work. The only way to "destroy an entanglement" is to bring the entangled particles back together. Suppose a proton A is entangled with a proton B. If B hits an anti-proton C, it gets converted into pure energy(maybe light and heat?). If it's impossible to destroy entanglement, then the subsystem consisting of the light and heat must be entangled with the original particle. Observations: * The dimension of the vector space has increased, since there may be many constituent photons released. So it may be impossible to assign a specific dimension to any quantum state. * What is the rule for determining the resulting quantum state? Is there a book or article? * If you convert a particle entirely into an electromagnetic wave or gravitational waves, and then reconstruct it, does that preserve entanglement? What is the rule for describing how the dimension of the vector space changes as it undergoes multiple transformations? If entanglement is allowed to propagate to a continuous field, then it seems like you'd have an uncountable infinite dimensional vector space to describe its state.
