# Dirac's Quantum Phase Problem

@article{Sperling2009DiracsQP, title={Dirac's Quantum Phase Problem}, author={Jan Sperling and Werner Vogel}, journal={arXiv: Quantum Physics}, year={2009} }

In 1927 the great physicist Paul A. M. Dirac failed to provide a consistent quantum description of the phase of a radiation field. Only one year later, he developed the famous Dirac theory of the electron, which led to the anti-particle -- the positron. We show that the reason for Dirac's failure with the phase problem bears a striking resemblance to his ingenious insight into the nature of the electron. For a correct quantum description of the phase of a radiation field it is necessary to take…
