Quantum interference is at the heart of many fundamental discussions in quantum mechanics. The most massive and complex objects for which quantum interference has been seen so far are the fullerenes C-60 and C-70. In our experiment the fullerenes were as hot as about 900 K.
We were still able to observe perfect interference fringes with no indication of any decoherence. Another interesting case occurs in multiphoton states where the nonlocal correlations in systems of at least three photons lead to an all-or-nothing conflict with classical expectation.
I will also briefly report on related experiments in quantum cryptography and quantum teleportation.
