Researchers at Purdue University have achieved a long-sought milestone, demonstrating what they call a “photonic transistor” that operates at single-photon intensities. There are few technologies more ...

Modern life runs on light. Fiber-optic cables move data across continents, lasers guide surgeries, and photons sit at the heart of quantum technologies. Yet one long-standing goal has remained elusive ...

This work demonstrates a novel method for continuously tuning single-photon nonlinearity using engineered Rydberg states, paving the way for more controllable and scalable quantum technologies Web of ...

There are few technologies more fundamental to modern life than the ability to control light with precision. From fiber-optic communications to quantum sensors, the manipulation of photons underpins ...
