IBM Quantum Computer Simulates Real Magnetic Materials and Matches Lab Data

1 month 3 weeks ago
"IBM says its quantum computer can now simulate real magnetic materials and match actual lab experiment results," writes Slashdot reader BrianFagioli, "which is something people have been waiting years to see." Instead of just theoretical output, the system reproduced neutron scattering data from a known material, meaning it lines up with real world physics. It still relies on a mix of quantum and classical computing and this is a narrow use case for now, but it is one of the first times quantum hardware has produced results that scientists can directly validate against experiments, which makes it a lot more interesting than the usual hype. Classical computers "are not great at modeling quantum systems," according to this article at Nerds.xyz. "The math gets messy fast, and scientists end up relying on approximations... Quantum computers are supposed to solve that problem..." If this direction continues, it could start to matter in areas like superconductors, battery tech, and even drug development. Those are the kinds of problems where better simulations can actually lead to better outcomes, not just nicer charts in a research paper. "I am extremely excited about what this means for science," said study co-author Allen Scheie from the Los Alamos National Laboratory. In an announcement from IBM, Scheie calls this "the most impressive match I've seen between experimental data and qubit simulation, and it definitely raises the bar for what can be expected from quantum computers."

Sony is Raising PlayStation 5 Prices Again, Between $100 and $150

1 month 3 weeks ago
Memory and storage shortages and price hikes have "steadily rippled outward across all kinds of consumer tech," reports Ars Technica. "Today's bad news comes from Sony, which is raising prices for PlayStation 5 consoles in the US just eight months after their last price hike." The drive-less Digital Edition will increase from $500 to $600; the base PS5 with an optical drive will increase from $550 to $650; and the PS5 Pro is going up from $750 to a whopping $900. At the beginning of 2025, these consoles cost $450, $500, and $700, respectively... RAM and flash memory chips are in short supply primarily because of demand from AI data centers — memory manufacturers have shifted more production toward making the kind of memory found in AI accelerators like Nvidia's H200, leaving less for the consumer market. And the situation is unlikely to improve any time soon, barring a major shift in demand from the AI industry.

Thousands of Americans Treated With Psilocybin in 2025

1 month 3 weeks ago
In a new 4,000-word article, CNN tells the story of a retired appellate paralegal and grandmother in her early 70s who was treated for depression with psilocybin. CNN notes there's now retreats featuring psilocybin in a few countries — and while psilocybin is illegal under United States federal law, "In Oregon, 5,935 clients received psilocybin services through Oregon's state-regulated program in 2025." High doses of psilocybin are effective in treating depression, a growing body of research suggests, with promise for other conditions, like PTSD and addiction, said Dr. Albert Garcia-Romeu, associate director of the Center for Psychedelic and Consciousness Research at Johns Hopkins University... Some researchers suggest it disrupts entrenched traffic patterns in the brain or grows new neuron connections to change thinking. Others say the results from psilocybin could have to do with its anti-inflammatory effect, Garcia-Romeu said... Colorado became the second state to make psilocybin legal with a 2023 law and issued its first healing center" last year. A law adopted in New Mexico last year established that state's Medical Psilocybin Program, now in development... Psilocybin seems to be "knocking on the door of FDA approval," said Dr. Lynn Marie Morski, president of the Psychedelic Medicine Association, which educates health care providers on the therapeutic use of psychedelics so they can answer patients' questions through the lenses of clinical evidence and harm reduction. Psilocybin therapy first received a "breakthrough therapy" designation for treatment-resistant depression from the US Food and Drug Administration in 2018, and now psilocybin drug products are on track to be submitted to the FDA for possible approval in the not-too-distant future. While psilocybin is illegal under United States federal law, more states are creating their own paths for legal use under state laws.
