Join ATARC as we continue our Quantum Working Group Speaker Series with Simon Hartley. Simon recently joined Cambridge Quantum in the role of US Cybersecurity Sales & Business Development. The new “Quantinuum” startup is US-owned, has $300+ million of funding, 150+ PHDs, and combines the world class Cambridge Quantum software and Honeywell Quantum hardware. During this talk we will discuss the security of today’s digital experiences that rely on layers of security infrastructure. Their foundations are key management, encryption algorithms, and key generation.  While the first two are frequently discussed, the issue of predictability in key generation itself is much less well known. This talk focuses on verifiable, tamper proof, and hardware independent key hardening from quantum physics that can easily be added to existing infrastructure, both classical and post quantum.
