If 2 particles are spin entangled, for example, they must both have their spins measured and compared. There are a variety of techniques and statistics, which vary according to the specific experiment and particle types. These aren't all easily described in lay terms, however. A common statistical test is the CHSH inequality, you can Google it to learn more. FYI: 2 entangled particles are described by a single wavefunction. It is a system of 2 particles, and not 2 independent systems. | |
