How to particles become entangled
WebFor entanglement between two different atoms in different locations (which can be meters apart or more), the spin of an atom is first entangled with emitted photons, and then the photons from two atoms are sent to the same optical element and measured in a specific way. After measurement, the spins of the two atoms become entangled. WebAug 4, 2011 · Theoretically, For making an entangled state, at first we have to make an "interaction" between the particles such as electrons, etc., i.e. we have to add a potential (between our particles) in our Hamiltonian, otherwise the state of our system is a multiple of state of single particles and so no correlation during every kind of measurement, …
