Dirac's Quantum Phase Problem

  title={Dirac's Quantum Phase Problem},
  author={Jan Sperling and Werner Vogel},
  journal={arXiv: Quantum Physics},
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…

Properties of a Polarization based Phase Operator

We define a Hermitian phase operator for zero mass spin one particles (photons) by taking account polarization. The Hilbert space includes the positive helicity states and negative helicity states

El operador de fase de Pegg y Barnett y la transformada discreta de Fourier

Phase is an irreplaceable variable in classical optics, so it is very important to investigate the observable representing this magnitude in quantum optics. Surprisingly, this observable is so hard



The quantum theory of the electron

The new quantum mechanics, when applied to the problem of the structure of the atom with point-charge electrons, does not give results in agreement with experiment. The discrepancies consist of

The Quantum Theory of the Emission and Absorption of Radiation

The new quantum theory, based on the assumption that the dynamical variables do not obey the commutative law of multiplication, has by now been developed sufficiently to form a fairly complete theory

Unitary Phase Operator in Quantum Mechanics

The difficulties in formulating a natural and simple operator description of the phase of a quantum oscillator or single-mode electromagnetic field have been known for some time. We present a unitary

The Hermitian optical phase operator realises Dirac's conception of a phase, conjugate to the photon number for a mode of the electromagnetic field. However, much confusion has resulted from the

Phase and Angle Variables in Quantum Mechanics

The quantum-mechanical description of phase and angle variables is reviewed, with emphasis on the proper mathematical description of these coordinates. The relations among the operators and state

Homodyne Detection and Quantum State Reconstruction

A review is given on phase-sensitive measurements, such as homodyne detection, for radiation fields and material systems. Methods of quantum-state reconstruction are considered for radiation fields,
