Backflash Attack on Coherent One-Way Quantum Key Distribution
Ashutosh Kumar Singh, Nilesh Sharma, Vaibhav Pratap Singh +1
In this article, we experimentally demonstrate an eavesdropper's (Eve's) information gain by exploiting the breakdown flash generated by the single photon avalanche detector (SPAD)…

Generation of Tunable Correlated Frequency Comb via Four-Wave-Mixing in Optical fibers
Aryan Bhardwaj, Debanuj Chatterjee, Ashutosh Kumar Singh +1
We report an all-fiber-based experimental setup to generate a correlated photon-pair comb using Four Wave Mixing (FWM) in Highly Non-Linear Fiber (HNLF). Temporal correlations of t…
