Photon statistics effects on a QRNG of vacuum fluctuations
(Optica Publishing Group, 2020-09-14)
Optical scattering enhances randomness characteristics, increases the chaotic behavior of coherent sources, broadens the distribution of photon statistics and makes it super-Poissonian which allows faster sampling compared ...
Down-conversion emission profile characterisation via camera
(Optica Publishing Group, 2020-12-14)
We present a method to improve the brightness and collection efficiency of the spontaneous parametric down-conversion source by monitoring the mode shape using camera and correcting it with collection optics.
Entanglement demonstration on board a nano-satellite
(Optica Publishing Group, 2020)
Polarization entangled photon-pairs are generated and detected onboard a 3U CubeSat in low-Earth orbit that violate Bell’s inequality with a CHSH parameter of 2.60 ± 0.06. These results pave the way for space-based quantum ...
Object ranging and sensing by temporal cross-correlation measurement
(SPIE, 2020)
We present a novel method to measure the range of an object in a lab setting. This is realised by utilizing the phase insensitive cross-correlation analysis of the probe and reference photons generated in a spontaneous ...
PYNQ-based rapid FPGA implementation of quantum key distribution
(IEEE, 2021)
In this paper, we present a real-time Quantum Key Distribution (QKD) implementation on Field Programmable Gate Arrays (FPGAs) for secure communication. We propose a novel methodology with a Python-based programming interface ...
Tracking capacitance of liquid crystal devices to improve polarization rotation accuracy
(Optical Society of America, 2017-08-21)
We report a capacitance tracking method for achieving arbitrary polarization rotation from nematic liquid crystals. By locking to the unique capacitance associated with the molecular orientation, any polarization rotation ...
