Quantum emitters: Beyond crystal clear to single-photon pure

Photons, fundamental particles of light, are carrying these words to your eyes via the light from your computer screen or phone. Photons play a key role in the next-generation quantum information technology, such as quantum ...

Scientists realize noiseless photon-echo protocol

Prof. LI Chuanfeng and Prof. Zhou Zongquan from University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) innovatively raised and realized noiseless photon echo (NLPE) protocol. The research ...

Underwater seismometer can hear how fast a glacier moves

Scientists show that an ocean-bottom seismometer deployed close to the calving front of a glacier in Greenland can detect continuous seismic radiation from a glacier sliding, reminiscent of a slow earthquake.

Urban traffic noise causes song learning deficits in birds  

Traffic noise leads to inaccuracies and delays in the development of song learning in young birds. They also suffer from a suppressed immune system, which is an indicator of chronic stress. A new study by researchers of the ...
