Observing the path less traveled boosts quantum gain

When probing the subtle effects of quantum mechanics, all the parameters in the system and its measurements need to be finely tuned to observe the result you are hoping for. So what happens when you gear everything towards ...

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.

Group's measuring tool probes solar-cell materials

Next-generation solar cells made from organic compounds hold great promise in meeting future energy needs, but researchers are still striving to gain a deep understanding of the materials involved – including the efficiency ...

Quantum logical operations realized with single photons

Scientists from all over the world are working on concepts for future quantum computers and their experimental realization. Commonly, a typical quantum computer is considered to be based on a network of quantum particles ...
