Quantum Cryptography

Overview

How can you tell a secret when everyone is able to listen in? In this course, you will learn how to use quantum effects, such as quantum entanglement and uncertainty, to implement cryptographic tasks with levels of security that are impossible to achieve classically.

By the end of the Quantum Cryptography course at Delft University of Technology (TU Delft) you will

• Be armed with a fundamental toolbox for understanding, designing and analyzing quantum protocols.
• Understand quantum key distribution protocols.
• Understand how untrusted quantum devices can be tested.
• Be familiar with modern quantum cryptography – beyond quantum key distribution.

This Quantum Cryptography course assumes a solid knowledge of linear algebra and probability at the level of an advanced undergraduate. Basic knowledge of elementary quantum information (qubits and simple measurements) is also assumed, but if you are completely new to quantum information additional videos are provided for you to fill in any gaps.

What you'll learn:

• Fundamental ideas of quantum cryptography
• Cryptographic concepts and tools: security definitions, the min-entropy, privacy amplification
• Protocols and proofs of security for quantum key distribution
• The basics of device-independent quantum cryptography
• Modern quantum cryptographic tasks and protocols
