Collapse and revival of entanglement between qubits coupled to a spin coherent state
Iskandar Bahari, Timothy P. Spiller, Shane Dooley +2
We extend study of the Jaynes-Cummings model involving a pair of identical two-level atoms (or qubits) interacting with a single mode quantized field. We investigate the effects of…
Experimental Two Way Quantum Key Distribution with Decoy State
Mohd Fared Abdul Khir, Mohd Norzaliman Mohd Zain, Iskandar Bahari +2
We report on the first demonstration of a two way Quantum Key Distribution protocol with decoy state. The experiment was conducted over free space medium and exhibits a significant…
Weak+Vacuum and One Decoy State with Two Way Quantum Key Distribution Protocol
M. F. Abdul Khir, Iskandar Bahari, S. Ali +1
We present relevant bounds for the case of weak+vacuum decoy state and one decoy state for a two way four states Quantum Key Distribution (QKD) protocol. The numerical simulation r…
Independent Attacks in Imperfect Settings; A Case for A Two Way Quantum Key Distribution Scheme
J. S. Shaari, Iskandar Bahari
We review the study on a two way quantum key distribution protocol given imperfect settings through a simple analysis of a toy model and show that it can outperform a BB84 setup. W…
Decoy States and Two Way Quantum Key Distribution Schemes
J. S. Shaari, Iskandar Bahari, Sellami Ali
We study the possible application of the decoy state method on a basic two way quantum key distribution (QKD) scheme to extend its distance. Noting the obvious advantage of such a…
