Why you should listen
Vikram Sharma is the founder and CEO of Canberra- based QuintessenceLabs, or Q-Labs, which uses quantum technology to strengthen cryptographic key management and encryption, an urgent need in this era of increasingly sophisticated cyberattacks. One of Westpac’s high-potential Businesses of Tomorrow, Q-Labs uses the world’s fastest random-number generator to create the strongest possible encryption keys, and integrates them into advanced key management and encryption capabilities, protecting banks, governments, and other security-aware enterprises around the globe.
Previously, Sharma founded two successful information-technology start-ups. He holds a Master of Science in Computer Science and a Doctorate in Quantum Physics from ANU, as well as a Master of Science in Management (Sloan Fellow) from Stanford University. He received the Pearcey State Award for Entrepreneurship in 2013.
