Detailed analysis of behavior of spin-entangled particle pairs under arbitrary rotations in their Hilbert space has been performed. It shows a rich range of varieties (faces) of entanglement in different bases. Analytic criteria are obtained for the respective faces of an entangled state. The corresponding conditions generally depend on both the state itself and the chosen basis. The most important result is revealing a deep analogy between a spin-entangled electronic qubit pair and momentum-entangled photon pair. Both cases exhibit coherence transfer from individual particles to nonlocal state of the system. This analogy allows us to predict certain features of the interference patterns in spin-entangled qubit pairs.

    A generalization of two-photon interferometry shows local detection probabilities are phase-independent for path-entangled photons, a known effect repackaged as a new principle of 'mutual intolerance'.
