1. GENERATION QI Next generation of quantum information scientists. Series of international schools for students in Gda sk. SUMMER SCHOOL ON QUANTUM CRYPTOGRAPHY (IMPLEMENTATIONS) University of Gda sk

2. Why Why the quantum the quantum cryptography cryptography? ? Quantum hardware will be able to crack RSA and other security assuring algorithms in a forseeable future Quantum cryptography offers security against quantum attacks Security of Quantum cryptography is unconditional in opposition to computational assumption based ones Quantum key distributions reaches commertial use nowadays Quantum security can be potentially extended in distance in a future Quantum Internet

3. who who ? ? Miko Miko aj aj Czechlewski Czechlewski (Institute of Informatics, University of Gda sk) (Attacks on quantum internet) Karol Horodecki Karol Horodecki (Institute of Informatics, ICTQT, University of Gda sk) (Attacks on quantum key distribution devices) Krystian Matusiewicz Krystian Matusiewicz (Intel Corporation, Gda sk) (Post-quantum cryptography) Gl ucia Murta (Heinrich-Heine-Universit t D sseldorf) (Anonymous quantum key distribution) Marcin Paw Marcin Paw owski owski (University of Gda sk) (Practical QKD protocols; attacks on QKD devices) Maciej Stankiewicz Maciej Stankiewicz (Institute of Informatics, University Of Gda sk) (private randomness as quantum cryptographic resource) Wo oncewicz oncewicz (ICTQT, University of Gda sk) Bianka Bianka Wo (Upper bounds on QKD key rates) Guilherme Xavier (Link ping University) (Practical QKD protocols)

4. For For whom whom ? ? The school is dedicated to students cryptography students who whish to learn basics of theory and practice of quantum We welcome those who are interested quantum-based security and quantum Internet interested in in academic academic/ /industrial industrial careeer related to development of The school introduces all the physics and mathematics needed to understand key key distribution distribution. Basic knowledge about algebra and probability theory is welcome. understand the the concepts concepts of quantum of quantum All the young applicants can contiue the studies in our master program Quantum Information Technologies Technologies at the University of Gda sk Quantum Information

5. Implementations Implementations of quantum of quantum cryptography cryptography Introduction Introduction to Quantum to Quantum Optics Optics (one day) Mathematical description of key optical components and their physical properties Practical Practical realizations realizations of quantum of quantum key key distribution distribution protocols protocols (one day) The practical issues arising in realization of QKD protocols for existing implementations and future possibilities Atacks Atacks on QKD and quantum networks on QKD and quantum networks(one day) Attacks on QKD protocols including: photon numer splitting, detector blinding and possible countermeasures Quantum Quantum secrecy secrecy beyond beyond QKD: post QKD: post- -quantum quantum cryptography cryptography(one day) Classical quantum-safe cryptography including lattice and hash based protocols Private Private Randomness Randomness (one day) Randomness extraction and amplification protocols and methods for proving their privacy
