In this follow-up video I go over the full details of cracking open any Master combination lock in 8 tries or less. In my previous video, I provided a simple...

A short video attempting to explain the Bennett & Brassard quantum cryptography protocol.

I've omitted any mention of the particular details of quantum physics that would be involved in actual real-world implementations, such as particle polarization axes, spin, and so forth, instead replacing them with abstract "processes" and freakish mysterious "machines". The physical details (interesting though they are) are not needed to understand the basics of the protocol, and I'm no physicist, so I'd probably mess them up if I tried (assuming I haven't already!).

Making these images has increased my affection for Microsoft PowerPoint, and putting them all into a video has hugely exacerbated my hatred for Windows Movie Maker.

NOTE:
An important missing piece of information: When Alice sends qubits to Bob, she chooses between process A and process B randomly for each qubit.

NOTE 2:
The following video explains BB84 as well, and gives more detail regarding the physics details:

27 юбилейная встреча Defcon Russia (на теплоходе!) Товарищи! Хотим сообщить в важных событиях в жизни нашей группы! 5 лет назад (15/06/2011) прошла первая встреча Defcon Russia. Мы решили отметить наш мини-юбилей (кстати, по такому событию прилетит Алексей Синцов!). И не просто отметить - а устроить..
