Quantum mechanics offers dramatically novel ways to process information. It is known that a fully functioning quantum computer would break some encrypting algorithms, such as RSA, which is used nowadays. However, quantum mechanics offers an alternative to standard cryptography, which cannot be broken by a quantum computer – the quantum key distribution. For this reason, designing and realizing quantum key distribution protocols in practice is a highly important task and involves a huge effort of theoreticians and engineers nowadays. Depending on the level of professional paranoia, there are different levels of trust toward devices realizing quantum key distribution, ranging from device dependent through semi-device dependent to fully device-independent quantum cryptography. Due to novel quantum hacker attacks which exploit imperfections of implementation, the lower levels of security need the significant effort of engineers to be useful for encryption.

The quantum world is always portrayed as something weird, spooky, and utterly impossible to comprehend. How can we ever hope to talk or reason about such a complicated thing? In this summer school you’ll learn how to do just that via a newly developed pictorial representation of quantum processes. This new representation is friendly and intuitive to work with, but at the same time is provably equivalent to the old way of doing things. Using these ideas we’ll explore the breadth of quantum theory, from foundational phenomena and quantum resources to quantum computing and cryptography.
