Scientists reach the ultimate quantum limit on a surface

Scientists have achieved a quantum breakthrough by creating an ultra-clean surface where individual molecules can maintain their delicate quantum properties at the fundamental limit. The discovery could unlock unprecedented control over molecules and help drive the next generatio

Metalens microscope switches focus with voltage, not moving optics

Just as it is difficult for a camera to keep both a nearby flower and a distant mountain sharply focused at the same time, conventional optical microscopes face a similar challenge when imaging structures located at different depths inside the body. Tighter focusing of light impr
