“…Fluorescent nanodiamonds (NDs) have emerged as important enablers of various technologies including quantum key distribution [1], quantum metrology [2], magnetometry [3,4], electrometry [5], decoherence [6] and thermometry [7]. There are now many color centers with identified room-temperature single photon emission properties [8], most of which show fluorescence in the near infra-red.…”

Tellurite glass fibers with embedded nanodiamond are attractive materials for quantum photonic applications. Reducing the loss of these fibers in the 600-800 nm wavelength range of nanodiamond fluorescence is essential to exploit the unique properties of nanodiamond in the new hybrid material. In the first part of this study, we report the effect of interaction of the tellurite glass melt with the embedded nanodiamond on the loss of the glasses. The glass fabrication conditions such as melting temperature and concentration of NDs added to the melt were found to have critical influence on the interaction. Based on this understanding, we identified promising fabrication conditions for decreasing the loss to levels required for practical applications.

“…Sources of single photons are relevant across many applications, as they can be used for quantum information processing, permitting longrange manipulation of quantum states for tasks such as quantum communication or distributed quantum computation [1]. Moreover, single-photon sources and in general quantum states of light have been considered a useful resource for establishing novel measurement methods in quantum metrology [2], [3]. Defects in nanodiamonds (NDs) also offer the possibility of a remarkably efficient implementation of several methods in nanoscopy [4] and they can serve as biomarkers [5].…”

Fluorescent emitters in diamond are considered to be a valuable resource for fields such as quantum communication, quantum photonics, and biological imaging. In this paper, we report a wide range of narrow bandwidth (∼1.5 nm) spectral emission lines arising from different color centers at room temperature. The defects were created by chemical vapor deposition of thin diamond films grown on silica substrates seeded with nanoparticles of diamond and nickel. These fluorescent lines also possess single or few centers photon statistics. We correlate the zero-phonon lines, observed using confocal microscopy, with previously identified nickel-related centers which have been observed in high-pressure high-temperature diamond, with a Si/Ni complex and silicon vacancy defects. We compare our findings with recent results demonstrating single-photon emission in diamond associated with nickel-related centers to clarify and summarize previous studies concerning this specific dopant. The great variety of emission lines observed in the synthesized material, mainly associated with nickel-related centers, could be an important resource for applications relying on the presence of several emitters of single photons in the same sample. Moreover, the possibility of mass production of these centers in nanodiamonds in colloidal suspension may provide an important resource for biomarking and microscopy.Index Terms-Confocal microscopy, diamond defects, singlephoton emission.

We report on the absolute calibration of a CCD camera by exploiting quantum correlation. This novel method exploits a certain number of spatial pairwise quantum correlated modes produced by spontaneous parametric-down-conversion. We develop a measurement model accounting for all the uncertainty contributions, and we reach the relative uncertainty of 0.3% in low photon flux regime. This represents a significant step forward for the characterizaion of (scientific) CCDs used in mesoscopic light regime. PACS numbers: Valid PACS appear hereIntroduction. The development of quantum metrology, imaging and sensing [1-6] based on quantum optical states aim to reach sensitivity beyond classical limits. For this reason it requires new detection strategies in the low light intensity regime (down to few photons), that are far from the ones where traditional radiometry operates [7]. Development of dedicated methods for absolute calibration of detectors in this context is therefore necessary, as it is widely recognised inside the radiometric community [8]. Some specific activities in this context are already on-going [9, 10], in particular related to the calibration of single-photon detectors exploiting the Klyshko's twinphoton technique [11][12][13][14][15][16][17][18] and its developments [19][20][21][22][23][24][25].In particular, demand for precise calibration of detectors both in mesoscopic light regime it is relevant not only from the point of view of the development of quantum technologies, but also for establishing a connection between the light intensity level typical of classical radiometric measurements and the quantum radiometry operating at single-photon level [8, 9]. Quantum correlations in twin beams offer an opportunity for reaching this goal, as discussed in [26][27][28][29].In [30] we realized the first absolute calibration of a standard CCD camera by exploiting bright squeezed vacuum. Standard CCD cameras, i.e. without any avalanche electro-multiplication, are able to count the number of generated photo-electron in each pixels for a given exposure time with a read-out noise ∆ RN of few photoelectron (for top-level devices), independent of the exposure time. However, a single photon can not be distinguished from the noise and the time resolution does not allow time tagging and coincidence of photon arrivals, instead the signal is proportional to the intensity (analog regime). If a light signal generate N photo-electron, under the condition ∆ RN << N 1/2 , sub-shot-noise sensitivity can be achieved [31][32][33], a properties that has been used also for quantum enhanced sensing and imaging protocols [2,33].The method in [30] is based on the sub-shot-noise measurement of photon number correlation between a pair
