# A Primer on Quantum Computation and Cryptography

Description | In the recent years quantum cryptography as well as computation has several times gained public attention. Sentences like "today crypto will be broken by quantum computers" or "quantum computers can compute exponentially faster than normal computers" can be read on many media articles and blog. But are those those statements actually true? |

In the recent years quantum cryptography as well as computation has several times gained public attention. Sentences like "today crypto will be broken by quantum computers" or "quantum computers can compute exponentially faster than normal computers" can be read on many media articles and blog. But are those those statements actually true? (Spoiler: Well yes they mostly are but only to some extend and in the correct context)

This talk gives a "short" introduction into the mechanics of a quantum computer and quantum communications. The complexity of the topic makes it's rather impossible to thoroughly understand quantum computers in the small amount of time a talk has. Instead this talk focuses on the basic mindset to comprehend the idea of quantum cryptography With that mindset it is already possible (to some extend) to discuss the the limits and possibilities of quantum computers. Additionally we will deal with the current state of development of quantum computers and quantum algorithms. In that context current plans of our politicians should be mentioned like the Quantum Manifesto of the European Union, where they talk about a "Quantum Internet" (http://qurope.eu/manifesto). If possible we can have a discussion afterwards (depends on the amount of listeners).

Basic understanding of linear algebra will be helpful in understanding this talk. The talk will be held in English.
