The head of IBM Research thinks that security-minded individuals should start looking into alternate forms of encryption and move their data today, as quantum computing is on the horizon. Some believe that quantum computers, capable of instantly breaking today's strongest security, could debut in as little as five years. Quantum computers can solve some types of problems near-instantaneously compared with billions of years of processing using conventional computers. Moler said people might feel safe because they have done everything they are supposed to do to secure their existing data -- but quantum computing will break it. "I do think that's scary," she said.
