SUMMARY:Singh\, A. (ECE) - Quantum Key Distribution Using Entangled Pairs with Random Grouping
DESCRIPTION:Quantum Key Distribution (QKD) provides information-theoretic security for cryptographic key establishment\, but existing protocols exhibit limited noise tolerance\, restricting their applicability in practical quantum channels with finite resources. This work introduces a QKD protocol based on entanglement swapping that significantly enhances error tolerance and key generation rates. The protocol encodes six-bit classical symbols into six-qubit entangled states organized as three Bell pairs. Key contributions include: (1) maintaining positive secrecy rates under 100% intercept-resend attacks\, unprecedented among existing protocols\, (2) proven security against collective attacks up to 29.29% quantum bit error rate (QBER)\, substantially exceeding BB84’s 11% threshold\, and (3) finite-key security analysis demonstrating viable key generation under practical block size constraints. These results establish that structured multi-qubit encoding fundamentally broadens the operational capabilities of quantum key distribution\, enabling secure communication in high-noise environments such as free-space satellite links and urban channels where conventional protocols fail. \nHost: Archana Jayprakash Singh\, Ph.D. Student\, Electrical and Computer Engineering  \nAdvisor: Zouheir Rezki  \nZoom- https://ucsc.zoom.us/j/92875779810?pwd=xIWhFkOw5WR3vyBvVhBCkd7ueJs2m2.1 \nPasscode- 530049
