Explore beyond the lectures: Physics Day @ NTUA 2024 is not just about lectures and presentations; it's a full experience designed to immerse you in the world of physics through interactive and engaging side events. Join us on 17th May 2024 for a day filled with unique opportunities to explore physics from multiple perspectives, connect with like-minded individuals, and participate in activities that extend beyond the traditional conference format.
Demonstration of the BB84 Protocol for Quantum Cryptography
Presenter: Dr Ioannis Theodonis
Cryptography is a fundamental process in communication that ensures a message will be readable only by the sender (Alice) and the receiver (Bob). For many years, mathematicians searched for a system that would allow Alice and Bob to exchange information with absolute security. In the 1940s, Claude Shannon proved that this goal is achievable if the two parties share a random secret key that is as long as the message they wish to exchange. Encryption/decryption is simply done by applying the binary addition of the key and the message. This cryptographic technique is called a one-time pad. The encryption of the message is impossible to break, even if there is infinite time and computational power to do so. Thus, the problem shifts to the secure transmission of the necessary key between Alice and Bob.
Quantum cryptography provides a solution to the above problem using communication protocols based on quantum physics. The process is generally called Quantum Key Distribution (QKD) and already has practical applications.
A Piece of ATLAS History
Presenters: Stelios Partsinevelos, Dimitris Xynis, Spyros Zonitsas, Thanos Koutsostathis
ATLAS is currently the largest particle detector and is located at CERN, just outside Geneva. Its primary role is the investigation of a wide range of particle physics phenomena via the analysis of the products of high-energy p-p collisions. The outer part of the ATLAS detector is dominated by the muon spectrometer, which consists of the Monitored Drift Tubes (MDT), the Cathode Strip Chambers (CSC), the Resistive Plate Chambers (RPC) and the Thin-Gap Chambers (TGC).
In this presentation, viewers will be given the opportunity to see a Barrel Inner Small MDT Chamber from the ATLAS detector. This presentation is courtesy of the ATLAS Division of the Experimental High Energy Laboratory of the National Technical University of Athens.
NKUA Young Minds Section
Presenters: Apostolis Tolis
Young Minds NKUA is a volunteer student group operating under the 'Young Minds' programme of the European Physical Society (EPS), with the main aim of communicating the science of Physics. It is the Young Minds section which is active in the Department of Physics of the National and Kapodistrian University of Athens (NKUA). At the same time, it is the oldest Greek section belonging to the program since 2021. We focus on creating a framework where students have the opportunity to come into contact with people with a common vision and dedication to science and develop their skills by participating in conferences around the world and in events we organize throughout the year, enriching their resumes with unique experiences. Additionally, our goal is also to communicate and popularise Physics to students and the general public.
