Special Issue Information

Dear Colleagues,

The study and application of optics is arguably one of the longest standing fields in physics that stretches from pre-Newtonian to post-Maxwellian eras. Famous pioneers involved in the discovery of contemporary quantum mechanics during the 1920s further helped to shed new light on electromagnetism that eventually led to the birth of quantum optics. Since then, creative applications of quantum optics have been engineered to improve measurement precisions, simulate nonclassical physics, and establish secure quantum protocols, among many other new-age endeavors.

The aim of this Special Issue is to highlight the recent topics of discussion in quantum optics. We hope to attract article contributions from all researchers and experts who are engaged in cutting-edge developments in the field of quantum optics. We encourage authors to submit either research or review articles in areas in, but not limited to, the list below:

  • Quantum imaging;
  • Quantum sensing and metrology;
  • Optical lattices and photonic quantum simulation;
  • Optical angular-momentum and extended spatial-mode photonics;
  • Time/frequency quantum optics;
  • Light–matter interaction and quantum optomechanics;
  • Quantum nonlinear optics;
  • Quantum coherence;
  • Cavity quantum electrodynamics;
  • Photonic solid-state devices.

We believe that this Special Issue will help to trigger new and exciting frontiers and applications that will subsequently evolve this important field in quantum physics to new scientific heights.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Quantum Reports is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1200 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

We study two families of four-photon superpositions of the Fock states: even vacuum squeezed states (EVSS) and orthogonal-even coherent states (OECS). These families are distinguished due to several properties: for certain values of parameters, they give the fourth-order uncertainty products close to the known minimal value (which is lower than for the Gaussian states); they have equal dimensionless values of the second- and fouth-order moments of the coordinate and momentum for all values of parameters; they possess zero covariances for all values of parameters. Since these states are obviously non-Gaussian, we consider them as good candidates to compare several different measures of non-Gaussianity proposed by different authors for the past fifteen years. The reference Gaussian states in all examples are thermal states dependent on a single parameter (an effective temperature or the coordinate variance). We analyze the measures based on the normalized Hilbert–Schmidt distance and the relative entropy (introduced by Genoni–Paris–Banaszek), the fidelity measure (Ghiu–Marian–Marian) and its logarithmic analog (Baek–Nha), as well as the Mandilara–Karpov–Cerf “Gaussianity parameter”. These measures are compared with the kurtosis of the coordinate probability density and with the non-Gaussian behavior of the Wigner function. Full article
