Important announcement

Dear visitor,

Please note that this OpenCourseWare platform will be replaced at the end of 2026 by a new platform (under the same url ocw.tudelft.nl).

Courses and their contents that are currently available the platform will partly be migrated. URL’s for this content will change and content might be unavailable for some time. In addition, some courses will not be available anymore.

If you are linking to specific courses on this platform (for instance for your students), please take timely measures to avoid problems with access. Possible actions are:

  • Download the materials to your local platform (laptop, server)
  • For educators only (including TU Delft lecturers): Contact us at ocw@tudelft.nl and inform us what course you are using in what context (institute, program, period of use, number of students). We will research (in collaboration with the authors of the course) and decide if we will migrate the course, and if yes, can supply you with a new url.

Thank you.

Home Courses Quantum Cryptography

Introduction

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.

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.

By the end of the course 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 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.

You will 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

MOOC information

The course materials used in this MOOC are available on TU Delft OpenCourseWare and can be viewed and downloaded for free. If you enroll for the MOOC, you will be introduced to up to date techniques in web lectures and webinars. Also, you will apply each technique to a case with fellow learners. Ultimately, the combination of these techniques provides a coherent analysis of the problem. If you want to enroll, go to https://online-learning.tudelft.nl/courses/quantum-cryptography/ to learn when the next run will start
