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. ...

One step closer to complex quantum teleportation

The experimental mastery of complex quantum systems is required for future technologies like quantum computers and quantum encryption. Scientists from the University of Vienna and the Austrian Academy of Sciences have broken ...

Coding theorem defines decoding error capacity for general scenarios

The rate at which information can be coded so that it can be decoded within a particular error probability constraint is one of the "major research topics in information theory" as Hideki Yagi at the University of Electro-Communications, ...

Silicon-based optical modulator for ultra-fast telecommunications

Imagine being able to download 10 high-definition movies (each of 4 GB capacity) in less than 1 second or be able to enjoy superior lag-free online gaming experience with multiple players from anywhere in the world. Researchers ...

Physicists create new 3D microchip

Scientists from the University of Cambridge have created, for the first time, a new type of microchip which allows information to travel in three dimensions. Currently, microchips can only pass digital information in a very ...

DNA data storage: 100 million hours of HD video in every cup

Biological systems have been using DNA as an information storage molecule for billions of years. Vast amounts of data can thus be encoded within microscopic volumes, and we carry the proof of this concept in the cells of ...
