ABSTRACT

Single-photon sources are essential building blocks in future quantum computing and quantum communications systems. These new systems depend on the nonclassical nature of light, which has antibunching characteristics and sub-Poissonian photon statistics.  Many such sources have been studied previously, for example, atoms/ions, quantum dots, and color centers.  The challenge of working with these single-photon sources lies within isolating individual tiny particles.  The experimental procedure for isolating single nanocrystals doped with erbium ions that are capable of emitting photons at a wavelength of 1550 nm will be explained.  Then, results of photon-counting experiments for light detected in an optical trapping experiment of upconverting nanoparticles (UCNPs) using a superconducting nanowire single-photon detector will be discussed.  There will also be an opportunity to display the nanoantenna enhanced optical fiber tweezer that was made for this purpose.
