alternative_right shares a report from Phys.org: A team of researchers working at Quantinuum in the United Kingdom and QuSoft in the Netherlands has now developed a quantum algorithm that solves a specific sampling task -- known as complement sampling -- dramatically more efficiently than any classical algorithm. Their paper, published in Physical Review Letters, establishes a provable and verifiable quantum advantage in sample complexity: the number of samples required to solve a problem. "We stumbled upon the core result of this work by chance while working on a different project," Harry Buhrman, co-author of the paper, told Phys.org. "We had a set of items and two quantum states: one formed from half of the items, the other formed from the remaining half. Even though the two states are fundamentally distinct, we showed that a quantum computer may find it hard to tell which one it is given. Surprisingly, however, we then realized that transforming one state into the other is always easy, because a simple operation can swap between them."

U.S. battery storage installations hit a record 57.6 GWh in 2025, and Texas is now poised to surpass California as the nationâ(TM)s largest storage market in 2026. Electrek reports: According to the US Energy Storage Market Outlook Q1 2026 from the Solar Energy Industries Association (SEIA) and Benchmark Mineral Intelligence, installations are now four times higher than totals from just three years ago. The US had a total of 137 GWh of utility-scale storage installed as of 2025, plus 19 GWh of commercial and industrial systems and 9 GWh of residential storage. Analysts expect the growth streak to continue. More than 600 GWh of energy storage is projected to be deployed nationwide by 2030, even as the Trump administration targets clean energy industries. Two-thirds of utility-scale storage installed in 2025 was built in red states, including nine of the top 15 states for new installations. Texas is projected to surpass California as the countryâ(TM)s largest battery storage market in 2026. Standalone battery projects accounted for nearly 30 GWh of new capacity in 2025, while solar-plus-storage installations made up about 20 GWh. Residential storage deployments reached 3.1 GWh last year, a 51% increase year-over-year. Analysts say virtual power plant programs in states such as Massachusetts, Texas, Arizona, and Illinois are helping drive adoption by reducing costs and easing strain during peak demand periods. The supply chain is shifting to support the boom. In 2025, some battery cell manufacturers pivoted production from EV batteries to dedicated stationary storage cells, converting existing lines and adjusting future plans. Lithium-ion cell manufacturing for stationary storage reached more than 21 GWh in 2025, enough to power Houston overnight, according to SEIAâ(TM)s Solar and Storage Supply Chain Dashboard. Meanwhile, US factories now have the capacity to manufacture 69.4 GWh of battery energy storage systems annually.

An anonymous reader quotes a report from the Guardian: When two men knocked on Ida Huddleston's door last May, they carried a contract worth more than $33m in exchange for the Kentucky farm that had fed her family for centuries. According to Huddleston, the men's client, an unnamed "Fortune 100 company," sought her 650 acres (260 hectares) in Mason county for an unspecified industrial development. Finding out any more would require signing a non-disclosure agreement. More than a dozen of her neighbors received the same knock. Searching public records for answers, they discovered that a new customer (PDF) had applied for a 2.2 gigawatt project from the local power plant, nearly double its annual generation capacity. The unknown company was building a datacenter. "You don't have enough to buy me out. I'm not for sale. Leave me alone, I'm satisfied," Huddleston, 82, later told the men. As tech companies race to build the massive datacenters needed to power artificial intelligence across the US and the world, bids like the one for Huddleston's land are appearing on rural doorsteps nationwide. Globally, 40,000 acres of powered land - real estate prepped for datacenter development -- are projected to be needed for new projects over the next five years, double the amount currently in use. Yet despite sums that often dwarf the land's recent value, farmers are increasingly shutting the door. At least five of Huddleston's neighbors gave similar categorical rejections, including one who was told he could name any price. In Pennsylvania, a farmer rejected $15m in January for land he'd worked for 50 years. A Wisconsin farmer turned down $80m the same month. Other landowners have declined offers exceeding $120,000 per acre -- prices unimaginable just a few years ago. The rebuffs are a jarring reminder of AI's physical bounds, and limits of the dollars behind the technology. [...] As AI promises to transcend corporeal fallibility, these standoffs reveal its very physical constraints -- and Wall Street's miscalculation of what some people value most. In the rolling hills of Mason county and farmland across America, that gap is measured not in dollars but in something harder to price: identity.
