  • Quantum safe cryptography – waiting to save the world
    Future quantum computers will one day bring us many great benefits. Unfortunately they will also break many of the cryptographic protocols on which current Internet security depends. Google’s quantum supremacy breakthrough notwithstanding, this is still most likely many years off. However, sensitive data intercepted and stored today, or long lifecycle ... read more

  • Finding winners: quantum startups
    Quantum computing makes headlines, but its sister technologies of quantum cryptography and quantum sensing are reaching market sooner. The first quantum revolution began in 1901 when Max Planck showed that the light emitted from a heated black-body consists of discrete quanta, later dubbed photons. Nature turns out to be built ... read more
