Experimental demonstration of quantum digital signatures over 43 dB channel loss using differential phase shift quantum key distribution

Abstract Ensuring the integrity and transferability of digital messages is an important challenge in modern communications. Although purely mathematical approaches exist, they usually rely on the computational complexity of certain functions, in which case there is no guarantee of long-term security...
