Prepare and Measure Quantum Digital Signature: Difference between revisions

Digital Signatures (DS) allow for the exchange of classical messages from sender to multiple recipients, with a guarantee that the signature has come from a genuine sender. Additionally, it comes with the properties of transferability, i.e. messages with DS can be forwarded from one recipient to another such that DS is verifiable to have come from the original sender, and non-repudiation, i.e at any stage after sending the message to one recipient, sender cannot deny having sent the message and corresponding DS. The lowest network stage at which this functionality can be achieved is [[First Network Stage: Prepare and Send Quantum Network|Prepare and Send Quantum Network]].<br/>
