Twin Quantum Cheshire Cats    [PDF]

Issam Ibnouhsein, Alexei Grinbaum

In an experiment with both pre- and post-selection one can find a photon (the
cat) in one place and its polarization (the smile) in another. Aharonov et al.
asked recently whether more than two degrees of freedom could be separated in
the same way. We show that this is possible and that the separation of
properties from objects that carry them is in some situations even stronger.
