Seminar Quantum Cryptography
n the mid 1970s, the late Stephen Wiesner circulated a manuscript with a revolutionary idea: He proposed to leverage the laws of quantum mechanics, specifically the famous uncertainty principle, to devise a "quantum money scheme". In such a scheme banknotes are digital quantum information, which can be transmitted at the speed of light between users, but have the remarkable property that they are encoded in such a way that they are "unclonable". That is, a user cannot spend a banknote and keep a copy of it at the same time. This is impossible using classical information alone, as classical information can be copied arbitrarily. This work was eventually published in 1983 and was the igniting spark that initiated the field of quantum cryptography. Just like with Wiesner's original proposal, the general goal of quantum cryptography is to achieve functionalities or security notions that are impossible to achieve classically. In this seminar we will look at seminal works in quantum cryptography, such as the Bennett-Brassard quantum key distribution scheme or the BCMVV'18 quantum testing scheme.
The seminar proceeds as follows
- In the first meeting we will assign topics on a first-come-first-serve basis
- In the second phase students prepare a report and presentation, reporting to their assigned supervisor
- Towards the end of the semester there will be a block seminar where every participant needs to attend and present their topic
- At the end of the semester a written report on the assigned topic needs to be submitted.
- The final grade will be determined based on both the presentation and the report
Requirements: - Attended and passed the core lecture cryptography
