ABOUT THIS COURSE
How to reveal a secret when everyone can listen to it? 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.

This interdisciplinary course is an introduction to the exciting field of quantum cryptography, developed in collaboration between QuTech at Delft University of Technology and the California Institute of Technology.

At the end of the course, you:

– Be armed with a fundamental toolbox to understand, design and analyze quantum protocols.
– Understand quantum key distribution protocols.
– Understand how unreliable quantum devices can be tested.
– Become familiar with modern quantum cryptography – beyond quantum key distribution.

This course assumes a solid knowledge of linear algebra and probability at the advanced undergraduate level. A 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 to fill in any gaps.

WHAT YOU WILL LEARN
– Fundamental ideas of quantum cryptography
– Cryptographic concepts and tools: security definitions, min-entropy, confidentiality amplification
– Security protocols and proofs for quantum key distribution
– The basics of device-independent quantum cryptography
– Modern quantum cryptographic tasks and protocols
