A study published in Nano Letters demonstrates the use of quantum dots to create metasurfaces, enabling two objects to exist in the same space. Pohang University of Science and Technology (POSTECH) ...

Accurate alignment of quantum dots with photonic components is critical for extracting the radiation emitted by the dots. In this illustration, a quantum dot centered in the optical "hotspot" of a ...

For the first time in history, the production of semiconductor quantum dots has been achieved at room temperature using lab-designed proteins, Princeton chemists reported in a paper published in the ...

Light-based quantum technologies, such as quantum communication and photonic quantum computing, require reliable sources of individual photons and, ideally, pairs of entangled photons. Semiconductor ...

Recycling method The idea to recycle these particles came up during a team discussion about the high cost of wasted quantum dots. Dillon Downie, a Ph.D. student in the Institute of Photonics at the ...
