Figure 1: Level structure of quantum dot and spin manipulation. In order to tackle the large energy difference, we use a frequency downconversion technique that converts a single 910-nm photon into a ...

In a step that brings silicon-based quantum computers closer to reality, researchers at Princeton University have built a device in which a single electron can pass its quantum information to a ...

This report both complements and extends Technical Reports Series No. 277/2, Absorbed Dose Determination in Photon and Electron Beams - An International Code of Practice, IAEA Technical Reports Series ...

A quantum light source demonstrates that light-sensitive cells in frog eyes can detect single photons. Miniature light detectors in frog eyes known as retinal rod cells are directly and unambiguously ...
