Researchers successfully achieved quantum entanglement between two quantum memory units 420km apart using an optical fibre link, exceeding previous limits.
ドイツの研究者らが、複素数を使わずに実数だけで量子力学を記述できることを示す論文を発表。従来の数学的アプローチとは異なり、物理的に自然な原理を出発点とし、量子力学の予測を再現する計算方法を導き出した。これにより、実数のみの量子理論が物理的に裏付けられた。
Physicists simulated "false vacuum decay," a theoretical scenario where a tiny cosmic bubble could expand and erase everything in its path. The experiment showed how a metastable "false vacuum" could tunnel into a lower-energy "true vacuum" via quantum effects, triggering destructive vacuum bubbles. The research does not suggest the universe is imminent collapse.
