ABSTRACT

Einstein’s Trojan horse, built for the fortress of quantum theory,

is contained in a publication that he authored together with

two young physicists, Boris Podolsky and Nathan Rosen, and is

generally called the EPR paper (Einstein, Podolsky, and Rosen,

1935). Einstein, Podolsky, and Rosen (EPR) presented a proof

that the use of probability or chance in quantum theory has very

unsettling consequences, because quantum theory teaches possible

correlations of two distant events. How can single events that are

random be correlated to other random single events? EPR suggests

that there are only two possible explanations:

• Quantum theory necessitates instantaneous influences, influences that propagate faster than the speed of light

in vacuum. These influences of distant events on each

other explain, then, the correlations of the two distant

events. Einstein was convinced that his relativity theory

had excluded the possibility of such influences, and if that

was the explanation, then quantum mechanics was simply

wrong.
