Last month, one of the three NIST finalists for post-quantum signature schemes has received its final nail in the coffin: Ward Beullens, a PostDoc at IBM Research, published a practical key recovery attack against the Rainbow signature scheme.

For years there has been persistent chatter that quantum computing is coming, and organizations should be prepared for its arrival. But what exactly is quantum computing and why should organizations be concerned about its impact on cybersecurity? This article explains what quantum computing is, when it is expected to arrive, and what is its anticipated impact on cybersecurity.
“Quantum computing” is computation performed using a computing device based on the strange, counter-intuitive physical properties of matter at very small scale, known as quantum mechanics.
