  • 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.

Quantum Navigation Takes to the Skies – with Sanket Deshpande and Ashwarya Das of Dirac Labs
Q: What first non-military applications do you anticipate for Dirac Labs' sensors?
Indoor navigation in large facilities and urban interiors is expected to be the initial commercial breakout, expanding to outdoor navigation in areas where GPS is weak or unavailable, such as factories, malls, and airports, within the next year or so.
Quantum Navigation Takes to the Skies – with Sanket Deshpande and Ashwarya Das of Dirac Labs
Q: What is the biggest misconception venture capitalists have about commercial readiness of quantum sensing compared to quantum computing?
Many people assume quantum sensing is a monolithic, equally mature technology across all platforms; in reality, sensing, navigation, and communication are at very different states, so education and context are crucial to understanding readiness for specific use cases like indoor navigation.
Q-Day 10x Closer Than We Thought—Pinnacle Paper Accelerates RSA Factoring — with Felix Thomsen and Paul Webster of Iceberg Quantum
Q: Can you explain the core modular components of your architecture and why they enable such efficiency?
We split the system into processing units that handle Clifford gates, a magic engine to supply non-Clifford gates, and a shared memory module. This modularity allows high parallelism, where memory can be reused by many processing units, reducing overall qubit needs while maintaining or increasing throughput.
1000x Faster and Cheaper – with Richard Givhan of Haiqu
Q: How accessible are these capabilities today to enterprise teams who want to start experimenting?
The guest confirms that the orchestration and SDK tools are fully productized and available now, with future releases giving more control over runtime chains and modular integration.
1000x Faster and Cheaper – with Richard Givhan of Haiqu
Q: Can you give a concrete example of the kind of impact Haiqu's tools can have on a typical R&D project?
A benchmark is shared where a molecular dynamics problem moves from $30,000 for nine hours on classical hardware to a $25, 30-second quantum-assisted run, illustrating dramatic savings in both time and cost.
