With Steven Herbert, University of Cambridge, formerly Quantinuum
Steven is the author of Quantum Computing: Foundations and Practice, an Affiliated Lecturer at the University of Cambridge and the former Head of Quantum Algorithms at Quantinuum. One of our deepest dives yet: is 2026 the moment quantum became real, which numbers to trust, and what quantum computers will actually do.

Episode 9
With Steven Herbert, University of Cambridge, formerly Quantinuum
Is 2026 the moment quantum became real, or is the excitement running ahead of the science? Steven on which industry numbers to trust, why Quantinuum bet on trapped ions, what quantum computers will actually do, and how to tell a real speedup from one that will not survive the best classical algorithms.
Episode 8
With Rahmadi Trimananda, Senior Research Engineer, Comcast
Comcast is running one of the most demanding post-quantum migrations anywhere. Rahmadi on where cryptography hides inside a company that size, why Comcast argued this year that the sky is not falling, and why a public key left on a blockchain is a different problem from a TLS handshake.
Episode 7
With Antti Ropponen, Executive Partner, IBM Consulting
IBM builds quantum computers and helps the world defend against them. Antti on whether the new government deadlines are realistic for a large enterprise, what a migration involves from first conversation to production, and why signatures and certificates lag behind encryption.
Episode 6
With Tommaso Gagliardoni, Horizen Labs and Lucumo Security
Researching quantum security since 2011, Tommaso on why a forged signature may be more dangerous than stolen data, what should happen to Satoshi's coins, the biggest myths in quantum security, and his prediction for the month RSA-2048 falls.
Episode 5
With Eli Ben-Sasson, Co-Founder, StarkWare and Zcash
Why STARKs, built on hash functions, are considered quantum-resistant, what happens if AI starts breaking cryptography, and the lifeboat StarkWare has already built for Bitcoin. Eli on why Layer 2s inherit their security from the chain beneath them.
Episode 4
With Richard Lee, Chief Business Officer, Abelian
Abelian shipped lattice signatures two years before NIST finalised the standards, and made itself a privacy chain at the same time. Three tiers of privacy, what Google's paper changed, and what Hong Kong's banks are asking.
Episode 3
With Colton Dillion, Quip Network
A marketplace that sells idle quantum compute by the job, and an asset layer that makes the wallets you already use quantum-resistant without a fork. Proof of useful work, the D-Wave partnership, and why Bitcoin is at risk by 2028.
Episode 2
With Matteo Vena, Co-Founder, Riva Labs
Riva Labs builds a quantum-safe Ethereum wallet. Matteo on what breaks first, what migrates last, and why custody is the frontline.
Episode 1
With Graeme Moore, Head of Strategy, Project Eleven
Project Eleven runs the Q-Day Prize. Graeme on the real timeline, harvest-now-decrypt-later, and what "quantum-safe" has to mean in practice.
A new episode every week.
Head of Community, NaoX
Runs one of the largest post-quantum communities in Web3 across Discord, Telegram and X, and leads the Quantum Defenders ambassador program. Iuri is where the questions from the community meet the answers from the cryptographers.
Builders, cryptographers, custodians, exchanges. If you're doing the migration for real, come and talk about it.
