Quantum researchers are offering 1 Bitcoin to whoever cracks the biggest “toy version” of a Bitcoin key using Shor's algorithm on a quantum computer.
Abstract: The emergence of quantum computing poses a threat to classical cryptography algorithms, necessitating a shift to quantum secure cryptography. Hybrid protocols combining at least one ...
