Dr. Or Sattath - Quantum Money and Some of its Extensions
Date: Monday, August 31 2020, at 14:00pm (Israel time)
Abstract
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 describe a way to integrate quantum money in a system such as Bitcoin.
Based on the following works (with collaborators):
- A Quantum Money Solution to the Blockchain Scalability Problem QCrypt’20, In Quantum journal.
- Almost Public Quantum Coins (abs, pdf)
- Semi-Quantum Money (abs, pdf), AFT’19.
- Quantum Tokens for Digital Signatures (abs, pdf), QCrypt 2017.
