Secure quantum signatures using insecure quantum channels
TL;DR: In this paper, the authors presented a quantum signature scheme that does not require trusted quantum channels and proved that it is unconditionally secure against the most general coherent attacks, and showed that it requires the transmission of significantly fewer quantum states than previous schemes.
Experimental transmission of quantum digital signatures over 90 km of installed optical fiber using a differential phase shift quantum key distribution system.

TL;DR: This demonstration used a 90 km long differential phase shift QKD to achieve approximately one signed bit per second, an increase in the signature generation rate of several orders of magnitude over previous optical fiber demonstrations.
Experimental transmission of quantum digital signatures over 90-km of installed optical fiber using a differential phase shift quantum key distribution system

TL;DR: In this paper, the authors reported the first demonstration of quantum digital signatures over installed optical fiber as well as the longest transmission link reported to date, using a 90-km long differential phase shift quantum key distribution system to achieve approximately one signed bit per second.

Unconditionally Secure Quantum Signatures
Ryan Amiri,Erika Andersson +1 more
TL;DR: Signatures are different from, but no less important than encryption, which ensures the privacy of a message as mentioned in this paper, and allow for the exchange of messages from one sender to multiple recipients, with the guarantees that messages cannot be forged or tampered with and that messages also can be forwarded from one recipient to another without compromising their validity.

TL;DR: This paper aims to provide an accessible and comprehensive review of existing unconditionally secure secure signature schemes for signing classical messages, with a focus on unconditional or information-theoretic security quantum signature schemes.
