Abstract

Summary form only given. In quantum optics the usual way of treating polarization has been to use the Stokes parameters. Here we present a different approach starting from the quantum description of geometric rotation of polarization.

Polarization in Quantum Optics: A new Formalism and Two Experiments

Tedros Tsegaye, P. A. Usachev, Jonas Söderholm +6 more

We report on two quantum polarization experiments. The first one shows that three geometrical rotations can in principle be distinguished with certainty using two photons. The second experiment shows quantum polarization properties of classically unpolarized light. We outline a new treatment of polarization in quantum optics. Our formalism differs from the usual quantum description, which uses the Stokes operators. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.

A Stokes-Parameter Technique for the Treatment of Polarization in Quantum Mechanics

U. Fano

A technique is presented which adapts the Stokes method to quantum mechanics and serves to calculate polarization effects by means of Pauli matrices. Illustrative examples indicate that this technique may be not only convenient mathematically but also physically more transparent than previous methods.

Notes on Polarization Measurements

Andrea Aiello, J. P. Woerdman

We review a few useful concepts about polarization measurements in the quantum domain. Using a perfectly general formalism, we show how to build the quantum counterpart of some classical quantities like Stokes parameters and Mueller matrices, which are well known in classical polarization-measurement theory.

Quantum-Stokes-Parameter Description of Nonclassical Polarimetric Measurements Using Two-Polarization-Mode Fock States

Kazuyuki Muroo, Yoshitaka Takubo

We show that the quantum Stokes parameters aptly describe the nonclassical two-polarization-mode Fock states and the transformation of their polarization states. In this description, the two-polarization-mode Fock states are the simultaneous eigenstates of the first and second Stokes parameters. Transformations of the polarization states, which are caused, for example, by optically active media, are described by the rotations in the Stokes vector space, which are given by unitary operators generated from the Hermitian Stokes parameters. The SU(2) symmetry of the Stokes parameters provides two independent degrees of freedom of polarimetric measurements that can exceed the standard quantum limit.

Double refraction phenomena in quantum field theory

M. J. Stephen

ABSTRACT It is shown that the phenomena of double refraction—optical activity, Faraday rotation, Kerr effect, etc.—may be treated as scattering problems in quantum field theory. An expression for the scattering cross-section of an atom or molecule for photons may be easily obtained and from this expression using the idea of Stokes operators, equating their expectation values to the classical Stokes parameters, the usual quantum mechanical expressions for optical activity, etc. may be obtained. This approach does not require the ideas of refractive index or polarization of the medium, and emphasizes what are the actual observables in these experiments.
