I have decided to post once every week, weather and time permits, research paper or essay that are highly interesting.

Quantum Money with Classical Verification


We propose and construct a quantum money scheme that allows verification through classical communication with a bank. This is the first demonstration that a secure quantum money scheme exists that does not require quantum communication for coin verification.
Our scheme is secure against adaptive adversaries - this property is not directly related to the possibility of classical verification, nevertheless none of the earlier quantum money constructions is known to possess it.

Quantum Money was propsed by Scott Aaronson and Paul Christiano in there paper Quantum Money from Hidden Subspaces
