Rishov Saha, Sujit Biswas, Rajat Subhra Goswami, K Hemant Kumar Reddy

The verification of the intricate interaction between a series of quantum error correction techniques and a quantum key distribution scheme also known as BB84, through the IBM Quantum Experience as a simulator, allows for a detailed verification of the immunity of the …

Quantum Secure Biometric Authentication in Decentralised Systems

Tooba Qasim, Vasilios A. Siris, Izak J. Oosthuizen, Muttukrishnan Rajarajan et autres

Biometric authentication has become integral to digital identity systems, particularly in smart cities where it en-ables secure access to services across governance, trans-portation, and public infrastructure. Centralised archi-tectures, though widely used, pose privacy and scalabil-ity challenges due to the aggregation of sensitive …
