Quantum physics sets a speed limit to electronics

How fast can electronics be? When computer chips work with ever shorter signals and time intervals, at some point they come up against physical limits. The quantum-mechanical processes that enable the generation of electric ...

In the quantum realm, not even time flows as you might expect

A team of physicists at the Universities of Bristol, Vienna, the Balearic Islands and the Institute for Quantum Optics and Quantum Information (IQOQI-Vienna) has shown how quantum systems can simultaneously evolve along two ...

Closer to a simple and efficient method of quantum encryption

Banks and government departments are already investing heavily in quantum encryption that relies on laser beams. However, laser beams often release several photons at once or none at all. A team at Hebrew University developed ...
