Jos Uffink (U Minnesota): Schrödinger and the prehistory of the EPR argument


Abstract:
Although  Schrödinger only coined  the term "entanglement"  (Verschränkung)  in 1935,   he  had been worrying about  the phenomenon of (what we now call)  entanglement  for composite systems   since  1927.  Indeed, he gave up on his original interpretation of the wave function precisely  for this reason.  At that time,  he thought that Born's statistical interpretation of the wave function did not suffer from the same problem.  In November 1931, his unpublished notebooks  show that, in response to  a lecture in Berlin by Einstein on the photon box experiment, he already developed all essentials of what we now know as the EPR argument, (Einstein, Podolski and Rosen, 1935).   I will argue that  Schrödinger’s role in  the development of this argument have not yet  been  sufficiently appreciated by historians of  physics. Also,  I will comment on the differences between  Schrödinger’s and Einstein’s  views on the conclusions to be drawn from  this  argument.
