It is now well understood that the quantum computer wil l revolutionize our lives. For many\, the hope is that it will allow c omputers to solve problems deemed too complex for today’s systems. T his is the light side of quantum. For others\, the fear is that it wil l bring havoc to our communication networks. This is the dark side of quantum. As we all know\, with quantum it will probably be a bit of bo th. In this presentation\, we will briefly discuss what a quantum comp uter is and what it does. We will focus on the threat it creates for o ur cybersecurity infrastructure. Fortunately\, solutions against this threat exist. Some of them are classical\, with new mathematical probl ems underpinning cryptography. Others are quantum\, relying on the sam e quantum properties to counter the quantum threat. We will start with quantum random number generation (QRNG)\, improving entropy in all c ryptographic systems. Then we will turn to quantum key distribution (Q KD)\, which can be used as an additional layer of security in cybersys tems. We will perform a live demonstration of the most common QKD prot ocol\, the BB84 protocol\, and show several real-world implementations of QKD networks. Predicting the future is harder\, but we will still have a quick look at our crystal ball to glimpse at how these QKD netw orks could evolve into full quantum networks.

\nThis event starts at 3:30pm with refreshments\, followed at 3:45pm by a short presentati on by a local group. The invited presentation starts at 4pm.
