This shot shows the group’s highly broadband and bright optical parametric amplifier in action.
By first amplifying squeezed light with a multimode optical parametric amplifier, researchers increase its signal without adding noise—and enable simultaneous measurement of many...

Schematic comparison of carrier injection through a) 1 + 2 and b) 2 + 3 quantum interference within a semiconductor. The higher-order 2 + 3 process concentrates carriers into a narrower range of momentum-space directions and produces a more directional photocurrent.

Satellites crossing the night sky above the northern Atacama Desert in Chile during an hour. It’s a stack of a time-lapse video taken on October 15, 2025, about two hours after sunset. Some streaks are caused by planes, easily identified by blinking-colored lights, but most trails are from satellites. In the foreground is the dome of ESO’s Extremely Large Telescope, the world’s largest optical/infrared telescope, currently under construction atop Cerro Armazones. Behind it are the lasers of ESO’s Very Large Telescope (VLT) at Paranal Observatory, 22 km away.
