Physicists discover what controls the speed of quantum time
SMRTR summary
EPFL physicists have developed a breakthrough method to measure quantum time without external clocks by analyzing the spin of electrons emitted when materials absorb light. Using quantum interference patterns, they discovered that atomic structure directly controls transition speeds, with simpler structures taking longer - copper's 3D structure completed transitions in 26 attoseconds while chain-like materials took over 200 attoseconds, revealing fundamental insights about time in quantum mechanics.
