Summer School QUANTUM CRYPTOGRAPHY

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.
