Quantum computing poses a great opportunity but also a great threat to internet security; certain mathematical problems that form the basis of today’s most popular cryptographic algorithms will be much easier to solve with quantum than with “classical” computers. Recently, Chinese researchers have claimed that an existing algorithm can be used with today’s quantum computers to break the RSA algorithm, which is the fundamental basis of secure internet communication. At the same time, there are doubts about the reliability of the publication.
