Quantum illumination using polarization-path entangled single photons for low reflectivity object detection in noisy background
K. Muhammed Shafi, A. Padhye, C. M. Chandrashekar
Detecting object with low reflectivity embedded within a noisy background is a challenging task. Quantum correlations between pairs of quantum states of light, though are highly se…
Second-order correlations and purity of unheralded single photons from spontaneous parametric down-conversion
A. Padhye, K. Muhammed Shafi, C. M. Chandrashekar
Various quantum technology applications require high-purity single photons with high generation rate. Although different methods are employed to generate such photons, heralded sin…
Bright and polarized fiber in-line single photon source based on plasmon-enhanced emission into nanofiber guided modes
K. Muhammed Shafi, Ramachandrarao Yalla, Kali P. Nayak
We demonstrate a bright and polarized fiber in-line single photon source based on plasmon-enhanced emission of colloidal single quantum dots into an optical nanofiber. We show that…
Integration of silicon-vacancy centers in nanodiamonds with an optical nanofiber
Ramachandrarao Yalla, Y. Kojima, Y. Fukumoto +5
We experimentally demonstrate the integration of silicon-vacancy centers in nanodiamonds (SiV-NDs) with an optical nanofiber (ONF). We grow SiV-NDs on seed NDs dispersed on a quart…
Multi-bit quantum random number generator from path-entangled single photons
K. Muhammed Shafi, Prateek Chawla, Abhaya S. Hegde +3
Measurement outcomes on quantum systems exhibit inherent randomness and are fundamentally nondeterministic. This has enabled quantum physics to set new standards for the generation…
Bell-inequality in path-entangled single photon and purity of single photon state
K. Muhammed Shafi, R. S. Gayatri, A. Padhye +1
Different degrees of freedom of single photons have been entangled and are used as a resource for various quantum technology applications. We present a simple scheme to perform Bel…
Occurrence control of charged exciton for a single CdSe quantum dot at cryogenic temperatures on an optical nanofiber
K. Muhammed Shafi, Kazunori Iida, Emi Tsutsumi +2
We discuss photo-luminescence characteristics of CdSe core/shell quantum dots at cryogenic temperatures using a hybrid system of a single quantum dot and an optical nanofiber. The…
Efficient fiber in-line single photon source based on colloidal single quantum dots on an optical nanofiber
K. Muhammed Shafi, Kali P. Nayak, Akiharu Miyanaga +1
We demonstrate a fiber in-line single photon source based on a hybrid system of colloidal single quantum dots deposited on an optical nanofiber and cooled down to cryogenic tempera…
