On the way to quantum networks

Physicists at LMU, together with colleagues at Saarland University, have successfully demonstrated the transport of an entangled state between an atom and a photon via an optic fiber over a distance of up to 20 km—thus ...

Better light measurement through quantum cloning

(PhysOrg.com) -- "One of the things we have been studying is how the world works on a really small scale," Bruno Sanguinetti, a scientist at the University of Geneva in Switzerland tells PhysOrg.com. "At the quantum level, ...

New technique could make modeling molecules much easier

Much like the humans that created them, computers find physics hard, but quantum mechanics even harder. But a new technique created by three University of Chicago scientists allows computers to simulate certain challenging ...

New technique excites atoms and molecules using pulsed laser

The best method to obtain the most precise information on the inner structure of atoms and molecules is to excite them by means of resonant laser light. Unfortunately, just this laser light (above a certain intensity) can ...

Active noise control for a quantum drum

Researchers at the Schliesser Lab at the Niels Bohr Institute, University of Copenhagen, have demonstrated a new way to address a central problem in quantum physics: at the quantum scale, any measurement disturbs the measured ...
