Could quantum computing threaten our day to day security, and even the fabric of the internet? Researchers are increasingly concerned about the risks quantum technology poses to encryption.

Organisations need to act now, if they are they are to secure their data and their operations, argue this week's guests.

Ramy Shelbaya is CEO and co-founder of Quantum Dice. That’s a business spun out of Oxford university’s quantum optics lab –  and which is now using quantum mechanics to create a self-certifying quantum random number generator.

And Axel Poschmann is a cybersecurity expert with a background in both the industry and academia. Currently, he works at PQShield, another business with links to Oxford, and which specialises in quantum-resistant cryptography.

We asked them to explain why quantum threatens security, and what CISOs can do about it.
