Simple silicon coating solves long-standing optical challenge

Quick bursts of laser light, lasting less than a trillionth of a second, are used in a range of applications today. These ultrashort laser pulses have allowed scientists to observe chemical reactions in real-time, image delicate ...

Intelligent optical chip to improve telecommunications

From the internet, to fiber or satellite communications and medical diagnostics, our everyday life relies on optical technologies. These technologies use optical pulsed sources to transfer, retrieve or compute information. ...

Implementing a 46-node quantum metropolitan area network

Quantum key distribution (QKD) is a method used for secure or secret key exchanges between two remote users. Using secure communication, cyberscientists ultimately aim to establish a global quantum network. Existing field ...
