Beyond the QBER Threshold: A Temporal QBER Based Machine Learning Framework for Multi Attack Detection in BB84 QKD
Isha, Deepak Singh, Devesh Kumar +3
Conventional BB84 Quantum Key Distribution (QKD) systems rely on a fixed 11% Quantum Bit Error Rate (QBER) threshold to detect eavesdropping. However, stealthy attacks can remain b…
Rough Martingale Optimal Transport: Theory, Implementation, and Regulatory Applications for Non-Modelable Risk Factors
Sri Sairam Gautam B., Isha
The Fundamental Review of the Trading Book (FRTB) poses a significant challenge for exotic derivatives pricing, particularly for non-modelable risk factors (NMRF) where sparse mark…
Exploring Low-Dimensional Magnetism in Cobalt Vanadates, CoVO~(~=~Ca, Sr) : Crystal Growth and Magnetic Properties of Effective Spin-1/2 Zigzag Chains
Anzar Ali, Guratinder Kaur, Arvind Maurya +6
We report the successful growth of high-quality single crystals of \ACVO, a quasi-one-dimensional zigzag chain compound containing Co ions, using the optical floating zone m…
Local symmetry breaking and orbital glass behaviour in CoFe2O4
Soumya Shephalika Behera, Isha, Arvind Kumar Yogi +6
The structural distortions, orbital correlations, and electronic states in cobalt ferrite (CoFe2O4) were investigated using complementary characterisation techniques, including SR-…
