An anonymous reader quotes a report from Ars Technica: On Tuesday, Westinghouse announced that it had reached an agreement with the Trump administration that would purportedly see $80 billion of new nuclear reactors built in the US. And the government indicated that it had finalized plans for a collaboration of GE Vernova and Hitachi to build additional reactors. Unfortunately, there are roughly zero details about the deal at the moment. The agreements were apparently negotiated during President Trump's trip to Japan. An announcement of those agreements indicates that "Japan and various Japanese companies" would invest "up to" $332 billion for energy infrastructure. This specifically mentioned Westinghouse, GE Vernova, and Hitachi. This promises the construction of both large AP1000 reactors and small modular nuclear reactors. The announcement then goes on to indicate that many other companies would also get a slice of that "up to $332 billion," many for basic grid infrastructure. The report notes that no reactors are currently under construction and Westinghouse's last two projects ended in bankruptcy. According to the Financial Times, the government may share in profits and ownership if the deal proceeds.

Society Will Accept a Death Caused By a Robotaxi, Waymo Co-CEO Says

Slashdot.org - Tue, 10/28/2025 - 21:10

At TechCrunch Disrupt 2025, Waymo co-CEO Tekedra Mawakana said society will ultimately accept a fatal robotaxi crash as part of the broader tradeoff for safer roads overall. TechCrunch reports: The topic of a fatal robotaxi crash came up during Mawakana's interview with Kristen Korosec, TechCrunch's transportation editor, during the first day of the outlet's annual Disrupt conference in San Francisco. Korosec asked Mawakana about Waymo's ambitions and got answer after answer about the company's all-consuming focus on safety. The most interesting part of the interview arrived when Korosec brought on a thought experiment. What if self-driving vehicles like Waymo and others reduce the number of traffic fatalities in the United States, but a self-driving vehicle does eventually cause a fatal crash, Korosec pondered. Or as she put it to the executive: "Will society accept that? Will society accept a death potentially caused by a robot?" "I think that society will," Mawakana answered, slowly, before positioning the question as an industrywide issue. "I think the challenge for us is making sure that society has a high enough bar on safety that companies are held to." She said that companies should be transparent about their records by publishing data about how many crashes they're involved in, and she pointed to the "hub" of safety information on Waymo's website. Self-driving cars will dramatically reduce crashes, Mawakana said, but not by 100%: "We have to be in this open and honest dialogue about the fact that we know it's not perfection." Circling back to the idea of a fatal crash, she said, "We really worry as a company about those days. You know, we don't say 'whether.' We say 'when.' And we plan for them." Korosec followed up, asking if there had been safety issues that prompted Waymo to "pump the breaks" on its expansion plans throughout the years. The co-CEO said the company pulls back and retests "all the time," pointing to challenges with blocking emergency vehicles as an example. "We need to make sure that the performance is backing what we're saying we're doing," she said. [...] "If you are not being transparent, then it is my view that you are not doing what is necessary in order to actually earn the right to make the roads safer," Mawakana said.

Nvidia's New Product Merges AI Supercomputing With Quantum

Slashdot.org - Tue, 10/28/2025 - 20:30

NVIDIA has introduced NVQLink, an open system architecture that directly connects quantum processors with GPU-based supercomputers. The Quantum Insider reports: The new platform connects the high-speed, high-throughput performance of NVIDIA's GPU computing with quantum processing units (QPUs), allowing researchers to manage the intricate control and error-correction workloads required by quantum devices. According to a NVIDIA statement, the system was developed with guidance from researchers at major U.S. national laboratories including Brookhaven, Fermi, Lawrence Berkeley, Los Alamos, MIT Lincoln, Oak Ridge, Pacific Northwest, and Sandia. Qubits, the basic units of quantum information, are extremely sensitive to noise and decoherence, making them prone to errors. Correcting and stabilizing these systems requires near-instantaneous feedback and coordination with classical processors. NVQLink is meant to meet that demand by providing an open, low-latency interconnect between quantum processors, control systems, and supercomputers -- effectively creating a unified environment for hybrid quantum applications. The architecture offers a standardized, open approach to quantum integration, aligning with the company's CUDA-Q software platform to enable researchers to develop, test, and scale hybrid algorithms that draw simultaneously on CPUs, GPUs, and QPUs. The U.S. Department of Energy (DOE) -- which oversees several of the participating laboratories -- framed NVQLink as part of a broader national effort to sustain leadership in high-performance computing, according to NVIDIA.
