Special Issue Information

Dear Colleagues,

Single photon detection has gained a prominent role in the measurement of optical signals, driven by the need for ultimate sensitivity and temporal resolution in various scientific and industrial applications such as Fluorescence Lifetime Imaging (FLIM), Förster Resonance Energy Transfer (FRET), Quantum Key Distribution (QKD), and Laser Imaging Detection and Ranging (LIDAR) to name a few.

Different technologies and materials have been successfully exploited to reach single photon sensitivity. Remarkable results have been achieved with semiconductor devices as Single Photon Avalanche Diodes (SPADs), both in single channels and arrays, and their number-resolving counterparts, Silicon Photomultipliers (SiPMs). Even higher performance, but at the expenses of a higher cost and complexity, can now be routinely achieved with superconducting materials arranged in nanostructure like in Superconducting Nanowires Single Photon Detectors (SNSPDs).

This Special Issue of Applied Sciences on “Single Photon Avalanche Diodes and Superconducting Nanowire Single Photon Detectors” is dedicated, but not limited to the following aspects of single photon detectors:

  • physical modeling
  • device design and development
  • fabrication
  • front end and processing electronic
  • applications of single photon detectors

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. Applied Sciences is an international peer-reviewed open access semimonthly 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 2400 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 propose a new method to effectively improve the performance of a quantum key distribution with eight-state continuous variables by the photon subtraction method. This operation is effective in increasing and distilling Gaussian entanglement between quantum states, and can be easily realized by existing technology. Simulation results show that the channel-loss tolerance of the eight-state continuous variable quantum key distribution (CVQKD) protocol can be extended by the appropriate photon subtraction algorithm; namely, single-photon subtraction.
