Insider Brief
Researchers at National Tsing Hua University developed a room-temperature single-photon source that emits more than 2.3 billion photons per second, setting a new brightness record for this class of quantum devices.
The team combined perovskite quantum dots with silver nanocavity structures, achieving ultrafast emission, non-blinking operation, and a 435-fold increase in emission rate.
The technology could support future quantum communication, quantum photonics, and integrated quantum computing systems while operating without cryogenic cooling.
PRESS RELEASE — A research team led by Professor Hao-Wu Lin from the Department of Materials Science and Engineering at National Tsing Hua University (NTHU) has developed the world’s brightest room-temperature single-photon source, which uniquely combines ultrafast and non-blinking emission. The device emits more than 2.3 billion photons per second, setting a new global benchmark and marking a significant milestone toward practical quantum communication and integrated quantum photonic chips. This breakthrough has been published in Science Advances.
