The Quantum Industrial Base

Jordan Schneider·ChinaTalk·9d ago

Constanza Vidal Bustamante, Senior Researcher at CNAS and author of the landmark report Quantum’s Industrial Moment, joins ChinaTalk to map out how supply chains behind quantum computers wind through the US and China. Co-hosting are Chris Miller, author of Chip War, and Zachary Yerushalmi.Our conversation covers:What it takes to build a quantum computer — Inside the cryogenic supply chain, the helium-3 bottleneck, and why mining the moon might actually make sense.How export controls backfired — ...

No Jensen, Not All Compute is Created Equal

Aqib Zakaria·ChinaTalk·10d ago

is in Cape Town for two weeks… email Nick at nick@chinatalk.media if you’re interested in joining a ChinaTalk meetup!We’ve recently tried to pin down how much compute China actually has, approaching the question from both the supply and demand sides. We converged on roughly 2.5 to 2.8 million H100-equivalents. But a single aggregate figure only captures part of the picture.Jensen on ChinaOn Dwarkesh’s podcast last week, Jensen Huang argued that China already has enough compute to build frontier ...

DeepSeek V4

Irene Zhang·ChinaTalk·11d ago

Finally, DeepSeek V4 is here. The Pro and Flash models are available through DeepSeek’s website, mobile apps, and API access as of April 23, and the lab has also released its technical report.Bucking a recent trend of Chinese AI labs moving away from open source, V4 was released under the highly permissive MIT license. It performs admirably on various benchmarks and leads the pack of Chinese open models, but did not close the gap with closed models from the US, with the authors themselves admitt...

WarTalk: Out of Ammo + Polymarket

Jordan Schneider·ChinaTalk·14d ago

The Iran war burned through America’s L-RASM, JASSM-ER, and Tomahawk stockpiles — weapons designed for a Pacific fight against the PLA Navy, not the Iranian corvette fleet. Now Pentagon insiders are leaking that we can’t win a war over Taiwan, and it’s a six-year pipeline to refill magazines.Joining us: Bryan Clark of the Hudson Institute and former submariner; , former Green Beret now in defense tech; Eric Robinson, former OSC/NCTC analyst and 101st Airborne officer, now a lawyer; and .We discu...

Quantum 101

Jordan Schneider·ChinaTalk·17d ago

What exactly is quantum computing? Why does it matter, and what would it actually mean to “win” the quantum race? Zach Yerushalmi, CEO of Elevate Quantum, a Mountain West–based public-private consortium advancing the U.S. quantum ecosystem, and Chris Miller join the podcast to discuss.Our conversation covers…What Quantum Computing Actually Is — A primer on qubits, superposition, and why quantum computers aren’t “faster classical machines” but fundamentally different systems designed to simulate ...

Fixing the GaN Problem

Aqib Zakaria·ChinaTalk·18d ago

In the semiconductor industry, the Trump administration is striving to bring back critical technologies that slipped out of our hands decades ago. The U.S. has attracted billions of dollars in investment to stimulate cutting-edge logic manufacturing, the development of EUV lithography, and HBM production. However, the semiconductor ecosystem is a lot more than just AI chips. And if the administration wants secure supply chains, it should focus on another rising material: gallium.Just as Pluto is...

Jacob Stern·ChinaTalk·21d ago

A guest post by Jacob Stern:I work with Sid Sijbrandij, a technology entrepreneur who has taken a radically personalized and high-agency approach to fighting his osteosarcoma (bone cancer). Before meeting Sid, I was a product lead at 10x Genomics, a sequencing technology company developing novel tools for understanding biology. Sid was the first person I met who had used 10x tools to inform their care. I now run the enterprise of Sid’s care, pursuing a strategy of maximal diagnostics, making per...

Should the US Buy from CXMT?

The “RAMageddon” is here. Tears roll down gamers’ cheeks as AI ruins DDR5 prices. People are even giving RAM as wedding presents. Why is memory going to the moon, and what are the geopolitical implications?Source: PCPartPickerThe Big Three memory makers — SK Hynix, Samsung, and Micron — have dedicated increasing capacity to memory for AI, or HBM. High-bandwidth memory (HBM) is a product that stacks multiple DRAM dies for AI memory. The increased allocation toward high-margin HBM means that not e...
