Scientists Photograph One Strontium Atom — Tiny Blue Dot

追加: 2026-05-20

[00:00:00]A single atom caught on camera floating between two metal electrodes.

[00:00:05]>> [music] >> Researchers trapped a strontium ion in a vacuum chamber, then shone a laser that made it glow a [music] pale blue.

[00:00:14]The laser excites an electron, forcing it to emit a photon [music] that we can actually see with a high NA microscope. That tiny blue [music] dot is the whole atom, its nucleus and all its electrons, no more, [music] no less.

[00:00:30]Seeing an individual atom confirms we can control [music] quantum bits at the most fundamental level, a cornerstone for future quantum computers.

[00:00:40]So, the next [music] time you think atoms are invisible, remember they can shine bright enough for a photograph.
