Let’s consider a pair of particles [with their signals] comprising an isolated system. Any change in some property of either particle is due to the signal/s received from the other. Each particle has the knowledge of the signals emitted by it and the consequences of such signals on the other. This is a “continuous process” which may go simultaneously with increasing separation between the particles.

The entanglement of some property ,between the particles, even in the highest level of non-locality seems to be intuitively “natural” so long the system remains an isolated one, comprising the two particles and the signals exchanged between them.

Would it be correct to say that the entanglement of properties in the non-local context should not be considered as an injury to commonsense perceptions?

  • $\begingroup$ Measurement on one particle by a gadget may produce a signal but the wave function now is different, including the gadget itself at least for a short interval of time, the original wave function having collapsed. An instantaneous measurement of the same property on the other particle should give the entangled value produced by the exchange of signals prior to measurement on the first particle. It is not necessary that the signal produced by measurement on the first particle has to reach the second one $\endgroup$ – Anamitra Palit Aug 4 '12 at 6:04
  • $\begingroup$ Is this question in context of quantum mechanics ? I mean, to the extent i understand it, in QM particles don't need to send any "signals" to each other to exist in an entangled state. $\endgroup$ – user10001 Aug 5 '12 at 6:18
