A new class of quantum dots deliver a stable stream of single, spectrally tunable infrared photons under ambient conditions and at room temperature, unlike other single photon emitters. This breakthrough opens a range of practical applications, in...

Bright semiconductor nanocrystals known as quantum dots give QLED TV screens their vibrant colors. But attempts to increase the intensity of that light generate heat instead, reducing the dots' light-producing efficiency.

Imagine a cube on which light is projected by a flashlight. The cube reflects the light in a particular way, so simply spinning the cube or moving the flashlight makes it possible to examine each aspect and deduce information regarding its structu...

Gear trains have been used for centuries to translate changes in gear rotational speed into changes in rotational force. Cars, drills, and basically anything that has spinning parts use them. Molecular-scale gears are a much more recent invention ...

Scientists recruited a world-leading microscope to capture atomic-resolution, high-speed images of gold atoms self-organizing, falling apart, and then reorganizing many times before settling into a stable, ordered crystal.

When we grow crystals, atoms first group together into small clusters—a process called nucleation. But understanding exactly how such atomic ordering emerges from the chaos of randomly moving atoms has long eluded scientists.

Even though quantum communication is tap-proof, it is so far not particularly efficient. Researchers at the Max Planck Institute of Quantum Optics want to change this. They have developed a detection method that can be used to track quantum transm...
