Quantum Cryptography - From the basics of Quantum Mechanics to Secure Key Distribution

Christoph Hamsen

Quantum mechanics describes nature at the level of single particles. Its effects often defy our intuition and lead to "ridiculous" consequences. Recent advances have sparked novel technologies with implications for modern cryptography. In my talk, I will focus on the first quantum-cryptograpic protocol "BB84" which allows two parties to negotiate a provably secure private key by exchanging single photons known as quantum key distribution. I will introduce the physical basics, explain the working principle in detail and end with exciting developments and today's application via satelites.


Next time we meet at SSE (Se­cure Sys­tems En­gi­neer­ing), Mauerstr. 78-80.

The next meetup is a special Berlin Crypto meetup and not at our usual location at Mozilla Berlin.

Trouble finding us?
Enter the courtyard at Schlesische Str. 27 and go to the very end.
Take the entrance to your left and go up to floor 4.
Here's a map showing the precise location of the building.

We're a bunch of security enthusiasts. Mozilla is nice enough to give us the space, but this meetup and its leaders do not speak on behalf of Mozilla.
