Abstract

In this presentation a review about the current state of the art concerning the application of deterministic single photon sources for absolute radiometry, i.e. the calibration of single photon detectors, is given. At the Physikalisch-Technische Bundesanstalt, the German national Metrology institute, an extensive research is carried out to optimize single photon sources for this purpose. Different single photon sources are currently under investigation, these are sources based on defect centres in (nano-)diamonds, on molecules and on semiconductor quantum dots.

Single photon sources for quantum radiometry: a brief review about the current state-of-the-art

S. Kück, Marco López, Helmuth Hofer +17 more

Abstract Single-photon sources have a variety of applications. One of these is quantum radiometry, which is reported on in this paper in the form of an overview, specifically of the current state of the art in the application of deterministic single photon sources to the calibration of single photon detectors. To optimize single-photon sources for this purpose, extensive research is currently carried out at the European National Metrology Institutes (NMIs), in collaboration with partners from universities. Single-photon sources of different types are currently under investigation, including sources based on defect centres in (nano-)diamonds, on molecules and on semiconductor quantum dots. We will present, summarise, and compare the current results obtained at European NMIs for single-photon sources in terms of photon flux, single-photon purity, and spectral power distribution as well as the results of single-photon detector calibrations carried out with this type of light sources.

Toward the Realization of Single-Photon Sources for Radiometry Applications at Room Temperature

Kee Suk Hong, Hee‐Jin Lim, Dong-Hoon Lee +5 more

Single photon sources based on single emitters such as 2D materials and impurities in diamond are of great interest for many application fields including quantum communication, quantum metrology and quantum sensing. In photometry and radiometry, a single photon source, having the ability to emit only one photon in a well-defined time and frequency domain, represents a promising candidate to realize a photon number-based primary standard for quantum radiometry. At the Korea Research Institute of Standards and Science (KRISS), we have realized three kinds of single photon sources based on various single emitters at room temperature: silicon vacancy in diamond, defects in gallium nitride (GaN), and vacancy in hexagonal boron nitride (hBN). We found common factors related with the relaxation times of the internal states that indirectly affect the photon number stability. We observed a high photon number stability in the GaN emitter due to faster relaxation times compared with the hBN emitter, which on the other hand produced high rates of photons per second (> 106). Moreover, we demonstrate repeatable radiant flux measurements of a bright hBN single photon emitter for a wide radiant flux range from a few tens of femtowatts to one picowatt.

Quantum and Classical Characterization of Single/Few Photon Detectors

M. G. Mingolla, Fabrizio Piacentini, Alessio Avella +10 more

This paper's purpose is to review the results recently obtained in the Quantum Optics labs of the National Institute of Metrological Research (INRIM) in the field of single- and few-photon detectors calibration, from both the classical and quantum viewpoint. In the first part of the paper is presented the calibration of a single-photon detector with absolute methods, while in the second part we focus on photon-number-resolving detectors, discussing both the classical and quantum characterization of such devices.

Single-photon sources

Mark Oxborrow, Alastair G. Sinclair

The article surveys the state of the art in the design, development and application of devices for deterministically generating single photons on demand. Both the defined function and requisite form of such ‘single-photon’ sources are explained in detail. Their attributes and characteristics, in particular the photon-counting statistics of the light that they generate, are presented in conjunction with the experimental apparatus (most notably the Hanbury-Brown and Twiss interferometer) for measuring them. Promising applications of single-photon sources within quantum key distribution, quantum information processing, as well as metrology and fundamental tests of quantum mechanics, are described. The utility and relative advantages of single-photon sources vis-á-vis more conventional sources of light are explained in terms of application-specific requirements and the respective abilities of different sources to fulfil them. The article collects, classifies and sorts the most significant work towards realizing practical single-photon sources to date. Though emanating from a diverse set of technological disciplines, with different research and application objectives in mind, the relative advantages and drawbacks of each approach are assessed, to give the reader a broad yet coherent and critical review of a rapidly developing research front.

TOWARDS THE IMPLEMENTATION OF A SINGLE-PHOTON DETECTOR ABSOLUTE CALIBRATION SYSTEM WITH CORRELATED PHOTON-PAIRS

T. Ferreira da Silva, I B Couceiro, H.P. Grieneisen +1 more

Abstract − An experimental system using correlated photon pairs for absolute measurements of single-photon detectors quantum efficiency has been set up at the Brazilian National Institute of Metrology (INMETRO). The establishment of this methodology is of special significance for the absolute calibration of detectors, especially for near infrared range as an alternative to the conventional radiometric methods. This paper describes the preliminary implementation of this absolute calibration method. Our first experimental results are reported and the optimization of the system is pointed out for obtaining further improvements the near future.

Room-temperature single-photon sources: design, performance, and applications

Michael Barth, David Höckel, Lars Koch +4 more

Single photon sources are key devices for optical quantum information processing, miniaturized optical elements, as well as light standards. Several systems have been exploited so far such as semiconductor quantum dots, defect centers in diamond, alkali atoms, and parametric down-conversion sources. In this contribution we will review some of these sources and highlight their unique properties with respect to applications in quantum information processing. A focus lies on two different room temperature sources based on cavity-enhanced parametric downconversion and on nitrogen-vacancy centers in diamond.
