A recent study by Jussi Lindgren and Jukka Liukkonen supports an interpretation that…. It has been thought of as many things: a pointlike object, an excitation of a field, a speck of pure math that has cut into reality. ... Quantum Physics. To test this idea, the researchers built a detector out of a crystal of germanium the size of a coffee cup. All in all, he says, if gravity does cause collapse, the process has to be more complicated than Penrose originally proposed. ScienceDaily, 16 November 2020. ScienceDaily. However, until now, according to Ghaemi, tools to study systems with large numbers of interacting quantum particles and their novel properties have been extremely limited. “For 30 years, I had been always criticized in my country that I speculated on something which was totally untestable.”. "Quantum physics is the fundamental theory of nature which leads to formation of molecules and the resulting matter around us," said Ghaemi, assistant professor in CCNY's Division of Science. Development of new quantum algorithms, regardless of their direct application, will contribute to realize applications of quantum computers. Questions? By George Musser Sep. 7, 2020 , 11:00 AM. By cutting into fossils and examining growth rings, scientists learned how predatory dinosaurs got so big. Our results are new and motivate many follow up studies," added Ghaemi. That suggests gravity is not, in fact, shaking particles out of their quantum superpositions. It’s still more science fiction than science fact, but perfect energy efficiency may…, In the early evening of Sunday, October 7, 1900—120 years ago—Max Planck found the functional form of the curve that we now know as the…, A collaboration between researchers from The University of Western Australia and The University of California Merced has provided a new way to measure tiny forces…, For 100 years scientists have disagreed on how to interpret quantum mechanics. AAAS is a partner of HINARI, AGORA, OARE, CHORUS, CLOCKSS, CrossRef and COUNTER. Trapping and controlling electrons in…, Researchers have developed a new theory for observing a quantum vacuum that could lead to new insights into the behavior of black holes. Jan. 29, 2020 — Researchers have for the first time created and imaged a novel pair of quantum dots -- tiny islands of confined electric charge that act like interacting artificial atoms. Large objects, such as baseballs, vehicles, and planets, behave in accordance…, Calculations show how theoretical ‘axionic strings’ could create odd behavior if produced in exotic materials in the lab. © 2020 American Association for the Advancement of Science. It resists being placed into awkward combinations, or “superpositions,” of different states. Now, one of the most plausible mechanisms for quantum collapse—gravity—has suffered a setback. Patrick Windpassinger and his team demonstrate how light stored in a cloud of ultra-cold atoms can be transported by means of an optical conveyor belt…. Their…, In a very unusual way, the electrical and magnetic properties of a particular crystal are linked together — the phenomenon was discovered and explained at…. George Musser is a journalist based in New Jersey and author of Spooky Action at Distance. Physics November 23, 2020 Combining Quantum Physics and the Theory of Relativity: Sound-Waves From a Quantum … www.sciencedaily.com/releases/2020/11/201116092255.htm (accessed November 26, 2020).

"Our research has developed a quantum algorithm which can be used to study a class of many-electron quantum systems using quantum computers. City College of New York. “One could reasonably argue that … the juice isn’t worth the squeeze.”. Their paper, entitled "Creating and Manipulating a Laughlin-Type ?=1/3 Fractional Quantum Hall State on a Quantum Computer with Linear Depth Circuits," appears in the December issue of PRX Quantum, a journal of the American Physical Society. So let’s do it.” She says her team is working to create clouds of 100 million sodium atoms at a temperature just above absolute zero. So far it has not been possible to measure or observe it, but now new research from a Although Penrose praises the new work, he thinks it’s not really possible to test his version of the model. Hidden Diversity During the Age of Dinosaurs Revealed by Early Bird With Tall, Sickle-Shaped Beak, Tipping Point: Irreversible Hotter and Drier Climate Over Inner East Asia, Biology Textbooks Wrong? Quantum physics was a key focus of leading scientists at the third World Laureates Forum, which concluded in Shanghai on Sunday, as they addressed the … News 'Spooky' quantum movements seen happening to large objects.
