The result confirms a long-standing prediction about how energy levels are structured in a quantum system, closing a decades-old gap between theory and experiment. Details of the experiment and its significance for quantum physics research are being reported by science news outlets.","why":"A decades-old theoretical prediction in quantum physics has finally been confirmed experimentally, a notable scientific milestone.","tone":"positive","entities":["Caltech"],"summarized_at":"2026-10-02T04:13:15.167835Z","meta":{"via":"scan","lang":"en","term":"physics","source":"ScienceDaily","published":"Thu, 01 Oct 2026 03:08:51 GMT"},"nw":null,"promo":null,"kind":null,"importance":null,"hidden":false,"hide_reason":null,"judged_at":null,"title_en":"Caltech physicists measure quantum energy ladder predicted 40 years ago","section_name":"Science","category_name":"Physics","timeline":[{"captured_at":"2026-10-01T04:05:11.937110Z","rank":2,"volume":null},{"captured_at":"2026-10-01T05:27:52.154288Z","rank":4,"volume":null},{"captured_at":"2026-10-01T06:49:54.166426Z","rank":5,"volume":null},{"captured_at":"2026-10-01T08:12:17.848293Z","rank":7,"volume":null},{"captured_at":"2026-10-01T09:34:30.487849Z","rank":7,"volume":null},{"captured_at":"2026-10-01T10:56:34.370465Z","rank":7,"volume":null},{"captured_at":"2026-10-01T12:19:03.113724Z","rank":12,"volume":null},{"captured_at":"2026-10-01T13:41:17.577157Z","rank":9,"volume":null},{"captured_at":"2026-10-01T15:03:17.543178Z","rank":7,"volume":null},{"captured_at":"2026-10-01T16:25:19.577535Z","rank":12,"volume":null},{"captured_at":"2026-10-01T17:47:16.955585Z","rank":20,"volume":null},{"captured_at":"2026-10-01T19:09:40.756001Z","rank":23,"volume":null},{"captured_at":"2026-10-01T20:32:21.967067Z","rank":26,"volume":null},{"captured_at":"2026-10-01T21:54:20.810849Z","rank":28,"volume":null},{"captured_at":"2026-10-01T23:16:23.480462Z","rank":31,"volume":null},{"captured_at":"2026-10-02T00:38:21.280707Z","rank":32,"volume":null},{"captured_at":"2026-10-02T02:00:42.306635Z","rank":34,"volume":null}],"posts":[{"platform":"news","url":"https://news.google.com/rss/articles/CBMib0FVX3lxTE52dGhuV2RYRklPMVpYSk9ucVU3bG9xaFptRkpvd3doZF9CRF83Yk9hYkRMWU0tLUc5cTc1SzJCcWtjSkpCN3ZMQmhsdHl1MGtBeWg3ckR1UXNwVzNySDdwVEd4czExbGRENEtTMnV6Yw?oc=5","author":"ScienceDaily","title":"Caltech physicists finally measure a quantum energy ladder predicted 40 years ago","snippet":null,"posted_at":"2026-10-01T03:08:51Z","likes":null},{"platform":"news","url":"https://news.google.com/rss/articles/CBMibkFVX3lxTE5Pd1RpRTlPMzZEWWUwd0hUcmhwck5QeVB6RzZBVXVTLUk3UGp3WE1ldG5PZ21BUzlET1RVT0R4RFd1aHcwaGZrTU9HeWpjbmJ1STNucENZaElXeFNURE1GNk5ZOFdJbWVEeFMxbVh3?oc=5","author":"sciencedaily.com","title":"Caltech physicists finally measure a quantum energy ladder predicted 40 years ago","snippet":null,"posted_at":"2026-10-01T03:09:40Z","likes":null}],"elsewhere":[],"window":"7d"}}
