Testing the spin-statistics theorem with a pair of entangled particles — •Christian Roos1 and Hartmut Häffner1,2 — 1Institut für Quantenoptik und Quanteninformation, Otto-Hittmair-Platz 1, 6020 Innsbruck, Österreich — 2Dept. of Physics, University of California, Berkeley, CA 94720, USA
We discuss how the fundamental quantum statistical property of two identical particles can be directly accessed. For this we propose to entangle the two particles by using their internal degrees of freedom and then to exchange their positions conditioned on their respective internal state. Interfering the internal states locally, allows to distinguish fermionic from bosonic statistics, even if the particles' wave function overlap vanishes at all times. Possible experimental realizations using trapped ions or neutral atoms are outlined.
