Pseudothermal light based quantum random number generator
(IEEE, 2020-10-22)
The importance of quantum random number generators (QRNGs) is increasing day by day. An important aspect of any QRNG is the speed of the system. This paper introduces the theory behind a pseudothermal light based QRNG. ...
Entanglement demonstration on board a nano-satellite
(The Optical Society, 2020-07-20)
Global quantum networks for secure communication can be realized using large fleets of satellites distributing entangled photon pairs between ground-based nodes. Because the cost of a satellite depends on its size, the ...
Object tracking and identification by quantum radar
(SPIE, 2019)
Quantum Radar is a promising technology that could have a strong impact on the civilian and military realms. In this study we introduce a new concept design for implementing a Quantum Radar, based on the time and polarization ...
Efficient coupling of down-converted photon pairs into single mode fiber
(Elsevier, 2021-08-15)
We present the analysis of the down-conversion emission profile from a critically phase-matched type-I nonlinear crystal. The emission profile of the down-conversion modes shows asymmetry in cylindrical coordinate system ...
Effect of photon statistics on vacuum fluctuations based QRNG
(IOP Publishing, 2021-06)
The speed of quantum random number generators (QRNGs) is a major concern for practical applications. In this work, we introduce scattering as a method to enhance the randomness characteristics of the entropy source. This ...
Development of an aerial interface for extraction of the electrodynamic fingerprints of the single-photon detectors
(Wiley, 2021-12)
In this study, a novel structure of semi array of antipodal Vivaldi antenna is designed to extract the RF radiations from the single-photon detectors in a quantum key distribution system. The proposed antenna covers a ...
Effect of phase and spatial distinguishability of photon pairs on the entanglement fidelity
(SPIE, 2021)
Polarization entanglement based cryptography uses the photon pairs generated in a spontaneous parametric down-conversion process and guarantees the security through the violation of Bell's inequality. Certain experimental ...
Optimization of collection optics for maximum fidelity in entangled photon sources
(TÜBİTAK, 2020)
In this report, decoherence sources for entangled photons created by spontaneous parametric down-conversion phenomenon are studied. The phase and spatial distinguishability of photon pairs from orthogonal crystals reduce ...
Quantum signatures in a quadratic optomechanical heat engine with an atom in a tapered trap
(Optica Publishing Group, 2022-12)
We investigate how quantum signatures can emerge in a single atom heat engine consisting of an atom confined in a tapered trap and subjected to hot and cold thermal reservoirs. A similar system was realized experimentally ...
Noise-tolerant object detection and ranging using quantum correlations
(IOP Publishing, 2022-10)
Imaging, detection and ranging of objects in the presence of significant background noise is a fundamental challenge in optical sensing. Overcoming the limitations imposed in conventional methods, quantum light sources ...
