Design and Implementation of a Quantum-Assisted Digital Signature

Cryptography
We propose a new quantum-assisted digital signature (Q-DS) protocol based on the composite of truly random symmetric keys generated by quantum key distribution with secure standardized hash functions, which allows for high parameterization to provide ...

Hybrid Classical–Quantum Text Search Based on Hashing

Mathematics
The paper considers the problem of finding a given substring in a text. It is known that the complexity of a classical search query in an unordered database is linear in the length of the text and a given substring.
