Direction of magnetic field measured by 2 coherent electrons

[exponent137]

According to the article:
http://physicsworld.com/cws/article...tic-fields-using-long-lived-quantum-coherence :
Is it possible simply to explain mechanism, how two coherent spins of electrons measure direction of magnetic field. I think that this explanation does not need structure of cryptochromes.

Does magnetic field interrupt quantum coherence or .. ?

something to add! it was proved that no rotation, the electron does not run, just have time, spontaneous magnetic mutation are flowing, they flows, is not rotating!
