A single atom as a movable slit: Researchers realize Einstein's thought experiment in original form, observing quantum-classical transition.

Can a photon be caught behaving like a wave and a particle in the same run of an experiment? For almost a century, that ...

Laser spectroscopy is a powerful tool for atmospheric gas analysis, yet traditional methods face challenges due to atmospheric turbulence and significant energy loss. While dual-comb spectroscopy ...

Physicists have engineered photons that behave as if they inhabit a space far richer than the familiar three dimensions, ...

The low-altitude economy, as an emerging economic form, has experienced rapid growth in recent years. Given the significant increase in the number of drones and the frequency of flight activities, the ...

There are few technologies more fundamental to modern life than the ability to control light with precision. From fiber-optic communications to quantum sensors, the manipulation of photons underpins ...
