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 ...
Cryptographic security concerns on timestamp sharing via a public channel in quantum-key-distribution systems
(American Physical Society, 2022-07)
Quantum-key-distribution protocols are known to be vulnerable against a side channel attack that exploits the time difference in detectors' responses used to obtain key bits. The recommended solution against this timing ...
Attack to quantum cryptosystems through RF fingerprints from photon detectors
(IEEE, 2022-03)
The well-known RF penetration method is implemented on the quantum cryptosystems. In this study, RF radiations from the single photon detectors in a quantum key distribution system are intercepted. It was found that the ...
