Entanglement-based Quantum Key Distribution in the Daylight and Uplink Satellite Configuration: Proof-of-Principal Demonstration and Feasibility Test

Kaushik Joarder, Jakub Szlachetka, Piotr Kolenderski

Experimental realization of entanglement-based quantum key distribution (QKD) in a daylight uplink (ground-to-satellite) communication channel is highly challenging due to the very…

Ultrabright Sagnac-type source of non-degenerate polarization-entangled photon pairs using only off-the-shelf optical components

Jakub Szlachetka, Kaushik Joarder, Piotr Kolenderski

We develop a Sagnac-type source of ultrabright, non-degenerate, polarization-entangled photon pair that is highly stable and compact simultaneously. We use a long PP…

Loophole free interferometric test of macrorealism using heralded single photons

Kaushik Joarder, Debashis Saha, Dipankar Home +1

We show unambiguous violations of different macrorealist inequalities, like the LGI and the WLGI using a heralded, single-photon based experimental setup comprising one Mach-Zehnde…

qkdSim: An experimenter's simulation toolkit for QKD with imperfections, and its performance analysis with a demonstration of the B92 protocol using heralded photon

Rishab Chatterjee, Kaushik Joarder, Sourav Chatterjee +2

Quantum Key Distribution (QKD) is one of the most important aspects of quantum cryptography. Using laws of quantum mechanics as the basis for security, the key distribution process…

Near-100 % two-photon-like coincidence-visibility dip with classical light and the role of complementarity

Simanraj Sadana, Debadrita Ghosh, Kaushik Joarder +3

The Hong-Ou-Mandel effect is considered a signature of the quantumness of light, as the dip in coincidence probability using semi-classical theories has an upper bound of 50%. Here…
