Physicists Created an 'Electron Lighthouse' That Steers Current With Light - ScienceAlert
Physicists at the University of Michigan have developed an 'electron lighthouse' device that uses laser light to control the flow of electrons in semiconductors. This breakthrough allows for the manipulation of electrical currents without the need for traditional power sources.
Why it matters
This technology could lead to more efficient electronic devices and new methods for controlling quantum-scale processes.

From household conveniences like the indispensable air fryer to the variously sized screens we rely on for work and meme-browsing leisure, modern tech functions through the directed flow of electrons.
Yet electrons play by the weird rules of the quantum universe , displaying strange behaviors unseen in the macroscopic world, like the superposition that allows them to exist in many states until they're observed, à la Schrödinger's theoretically undead cat .
Sometimes, however, their odd activities do display real-world analogs that help us non-quantum-physicists wrap a fraction of our minds around unseeable processes.
