80 Year Old Copenhagen Interpretation of Quantum Mechanics Tested and Found Lacking

Experiments proposed by UCR’s A. N. Korotkov and A. N. Jordan (Univ. of Rochester) have shown that quantum measurement is not necessarily an either – or event as has been taught for 80 years. Instead, one can do a ‘little bit’ of measurement which causes a ‘little bit’ of collapse into an eigenstate of the system. However, this ‘little-bit’ of collapse can be un-collapsed in what Korotkov and Jordan term a ‘quantum undemolition’ experiment. This breakthrough experiment has been realized at UCSB in the group of John Martinis (in collaboration with Korotkov) and is described in Nature News.
