Im Rahmen der 6. Internationalen Konferenz für Quanten-, Nano- und Micro-Technologien (ICQNM 2012) wurden die AIT-Experten Dr. Stefan Schauer und Dr. Martin Suda mit dem Best Paper Award ausgezeichnet. Beide experten sind auf dem Forschungsfeld Optical Quantum Technology im AIT Safety & Security Department tätig.
Darüber hinaus wurden die AIT-Experten eingeladen eine Extended Version des Papers bei einem eigenen Journal zur Konferenz einzureichen.
Titel des Papers:
Security of Entanglement Swapping QKD Protocols against Collective Attacks
Abstract:
We discuss the security of quantum key distribution (QKD) protocols based on entanglement swapping against collective attacks. Therefore, we apply a generic version of a collective attack strategy on the most general entanglement swapping scenario used for key distribution. Further, we focus on basis transformations which are the most common operations performed by the legitimate parties to secure the communication. In this context we show that the angles which describe these basis transformations can be optimized compared to an application of the Hadamard operation. As a main result we show that the adversary’s information is reduced to a new minimum of about 0.45 which is about 10% lower than in other protocols.
