Quantum Encryption vs Quantum Computing: Will the Defense or Offense Dominate?
- Abstract
- Quantum encryption will soon provide unbreakable ciphers. Quantum computers will soon allow the cracking of every cipher. Does something sound contradictory about those statements? The fact is we have a bit of a dichotomy here, and with teams on both sides of the argument fervently pushing their contradictory visions it can be hard for computer security professionals to separate the fact from the hype. But that is what we are paid to do, and we have an obvious stake in how these technologies will change the future. This paper examines these topics by providing a snapshot of current research. We should start, however, with a short review of encryption today.
