Twisting up atoms through space and time

One of the most exciting applications of quantum computers will be to direct their gaze inwards, at the very quantum rules that make them tick. Quantum computers can be used to simulate quantum physics itself, and perhaps ...

An enhanced cooling method for the quantum world

The quantum nature of objects visible to the naked eye is currently a much-discussed research question. A team led by Innsbruck physicist Gerhard Kirchmair has now demonstrated a new method in the laboratory that could make ...

Venus: The trouble with sending people there

Venus, often called Earth's "evil twin" planet, formed closer to the sun and has since evolved quite differently from our own planet. It has a "runaway" greenhouse effect (meaning heat is completely trapped), a thick carbon-dioxide-rich ...

Making mini-magnets that induce a quantum anomalous Hall effect

A new device has been fabricated that can demonstrate the quantum anomalous Hall effect, in which tiny, discrete voltage steps are generated by an external magnetic field. This work may enable extremely low-power electronics, ...
