  • Great guests, cringey host

    Have to unsubscribe, the host asks the most basic questions as if he has put in no prep, doesn’t let guests really continue their line of logic.

Talking Points

Recent interactions between the hosts and their guests.

NVIDIA Architect Warns We Might Need to Rip and Replace Hardware for PQC – with TCG
Q: How does government regulation influence the speed of PQC adoption compared to enterprise, and what is the likely regulatory trajectory?
Governments tend to move faster due to mandates and procurement requirements; CNSA 2.0 and similar standards are pressuring PQC readiness, potentially making government procurement a leading indicator for broader industry adoption and creating incentives for enterprises to accelerate upgrades to avoid non-compliant equipment.
NVIDIA Architect Warns We Might Need to Rip and Replace Hardware for PQC – with TCG
Q: When would you expect that a typical server catalog would be ready to support PQC, and what timelines should organizations plan around?
Server offerings aligned to PQC readiness are expected around 2027, with widespread procurement clauses starting in 2027. However, complete adoption across all platforms could stretch into the late 2020s and beyond due to extended lifecycles of data centers and industrial control infrastructure.
NVIDIA Architect Warns We Might Need to Rip and Replace Hardware for PQC – with TCG
Q: Can we upgrade all hardware to PQC? And if not, how bad is the quantum technical debt problem?
Upgrading all hardware is not feasible in one go; many devices, especially high-value servers and critical infrastructure, will require hardware refreshes to achieve full PQC readiness. The transition will take years, with procurement starting around 2027 and longer timelines for enterprise adoption due to replacement cycles and certification requirements.
Slashing the Time to Quantum Advantage – with Toby Cubitt of Phasecraft
Q: But it's this idea where the need for the qubits keeps plummeting now and the actual physical qubits we have keep rising. So at some point, those two lines are going to cross. How should we think about that?
The guest explains that hardware progress has been steady and that algorithmic breakthroughs can dramatically reduce required quantum resources, potentially crossing timelines sooner than hardware alone would suggest; the emphasis is on hybrid, problem-specific approaches that maximize value with fewer cubits.
Computing on PQC-Encrypted Data – with Dr. Kurt Rohloff of Duality Technologies
Q: What are the most impactful use cases you foresee for FHE in regulated industries?
Key use cases include secure financial crime collaboration to identify threats across institutions without revealing sensitive data, rare-disease analytics by aggregating data from multiple healthcare sites, and secure AI workloads where queries and data are protected during inference and training, enabling collaborations that were previously impractical due to confidentiality concerns.
