Graph states, a class of entangled quantum states that can be represented by graphs, have been the topic ... such as the amplitude and phase of light. While graph states have shown potential ...

The solution demonstrated by Xu et al. 1, circumvents the delay–bandwidth problem altogether, by taking a dynamic approach 2,3,8 to trap light. Their system consists of two dynamic resonators ...

The detection of light at the single-photon level is important for tasks ranging from fluorescence imaging to quantum information processing, reports Neil Savage. High-sensitivity detectors that ...
