Quantum waves seen in molecules

  1. Feb 26, 2004 #1
    In 1999, Zeilinger and his colleagues fired beams of "carbon-60" or "carbon-70" molecules (so named because each molecule contains 60 or 70 carbon atoms) at a device called a diffraction grating. The individual molecules spread out in wavelike patterns, creating "interference patterns" visible on a monitor. This proved that even very hefty molecules can experience quantum effects -- and, thus, can literally be in more than one place at a time, crazy though this sounds.

    I think you are about 4 years behind. The Zeilinger's group has gone on to publish a few more of these, the most recent one being the observation of wave-like nature in tetraphenylporphyrin and fluorofullerene.[1] These are at least twice as big as C70 molecules. They currently hold the record in terms of size and mass.
