Making quantum encryption practical

One of the many promising applications of quantum mechanics in the information sciences is quantum key distribution (QKD), in which the counterintuitive behavior of quantum particles guarantees that no one can eavesdrop on ...

A metronome for quantum particles

A new measurement protocol, developed at TU Wien (Vienna), makes it possible to measure the quantum phase of electrons—an important step for attosecond physics.

US eyes phase-out of old telephone network

America's plain old telephone network is rapidly being overtaken by new technology, putting US regulators in a quandary over how to manage the final stages of transformation.

Adding noise for completely secure communication

How can we protect communications against eavesdropping if we don't trust the devices used in the process? This is one of the main questions in quantum cryptography research. Researchers at the University of Basel and ETH ...

Durban climate deal leaves difficult road ahead

The world's nations on Sunday set their sights on a new all-encompassing pact on climate change that marks a break with the past and will also be gruelling to achieve.
