In Episode 145, Fred Chong returns to discuss what's new at Infleqtion, now a public company, and the work that's keeping him busy across both academia and industry. The team dig into Quantum for Bio, a multimodal cancer biomarker discovery project developed with Welcome Leap and now continuing with IBM, where hybrid quantum-classical algorithms are uncovering relationships between genes, RNA, and tumor imaging that classical methods haven't been able to tackle. Fred shares Peter Shor's perspective that the shortage of quantum algorithms reflects a shortage of good machines, not a shortage of ideas, and why that's an optimistic take. The conversation also covers neutral atoms as a maturing modality, Infleqtion's dual-species machine and how it reduces the need for physical qubit movement, and the concept of interleaving error-corrected qubit tiles to reduce long-range communication costs.

In Episode 144, Todd Brun, Professor of Electrical Engineering, Computer Science, and Physics at the University of Southern California, returns to break down where quantum error correction stands today. The team cover the transition from theoretical thresholds to real experimental demonstrations, why decoding latency matters as much as code quality, and the counterintuitive insight at the heart of quantum error correction — that you can measure what went wrong without measuring the data itself. Todd also weighs in on the trade-offs between modalities when it comes to implementing error correction in hardware, and closes with a look at how far the field has come since the early nineties when quantum computing was just an idea.

In Episode 143, Patrick and Ciprian break down Microsoft's Majorana 2 announcement and what it means for the future of topological quantum computing. The team cover the physics behind the tetron architecture, why switching from aluminum to lead in the nanowire construction matters, and what coherence times north of twenty seconds — and in some cases a full minute — represent for the field. The conversation weighs Microsoft's history of playing close to the vest, the DARPA program backing the approach, and the newly aggressive 2029 commercial timeline. Patrick and Ciprian also disclose their long history as Microsoft partners and VPs, and close with a broader look at where the modality race stands heading into what may be the final stretch of the NISQ era.
