Public-Key Cryptography Threatened by Quantum Computing

The development of a powerful quantum computer will completely undermine current, widely used public-key cryptography algorithms, including the RSA algorithm …

“In recent years, there has been a substantial amount of research on quantum computers – machines that exploit quantum mechanical phenomena to solve mathematical problems that are difficult or intractable for conventional computers. If large-scale quantum computers are ever built, they will be able to break many of the public-key cryptosystems currently in use. This would seriously compromise the confidentiality and integrity of digital communications on the Internet and elsewhere.”
