One of the unique aspects of quantum mechanics is the no-cloning theorem. This theorem has direct applications in quantum crpytography: quantum money is very similar to the cash we use, but in addition, it is physically impossible to forge.
In this talk, I will discuss quantum money, and some of its extensions (quantum coins, semi quantum money, tokens for digital signatures, quantum copy protection, and quantum lightning). I will also descrube a way to use quantum money in a system such as Bitcoin. Here, the main challenge is that the mint is not trusted - unlike the standard setting were the mint is assumed to be trusted.
