Using light to encrypt communications

Researchers of the UT found a new way to protect data from attacks with quantum computers. As they published today in New Journal of Physics. With quantum computers on the rise, we can no longer exclude the possibility that ...

Quantum information gets a boost from thin-film breakthrough

Efforts to create reliable light-based quantum computing, quantum key distribution for cybersecurity, and other technologies got a boost from a new study demonstrating an innovative method for creating thin films to control ...

Interdisciplinary UA researchers get tangled up in quantum computing

Good neighbors often share resources: a cup of sugar, extra lawn chairs, a set of jumper cables. Researchers across campus at the University of Arizona will soon be able to share a less common—and far more valuable—resource ...

Better safeguards for sensitive information

Despite being the most advanced quantum technology, secure encryption of information units based on a method called quantum key distribution (QKD) is currently limited by the channel's capacity to send or share secret bits. ...

Space-borne quantum source to secure communication

Soon, powerful quantum computers will be able to easily crack conventional mathematically encrypted codes. Entangled photons generated by a spaceborne quantum source could enable hack-proof key exchange for ultra high security ...
