The motion of magnetic objects can be made to interact with their internal acoustic waves. In this way, as physicists from Innsbruck show, nanoparticles can be cooled down to such an extent that they exhibit quantum properties.

Today, most quantum experiments are carried out with the help of light, including those in nanomechanics, where tiny objects are cooled with electromagnetic waves to such an extent that they reveal quantum properties. Now, a team of physicists led by Oriol Romero-Isart at the University of Innsbruck and the Austrian Academy of Sciences is proposing to cool microparticles with sound waves instead.

The Honorary Doctor Rainer Blatt with the Rector of the University of Madrid, Joaquín Goyache, and the Austrian Ambassador in Madrid, Christian Ebner.

For his scientific achievements in the field of quantum physics, experimental physicist Rainer Blatt received an honorary doctorate from the Complutense University of Madrid on Friday in Madrid. On Wednesday, Blatt was already accepted as a foreign member of the Spanish Academy of Sciences.

Facts check for quantum computers

In a recent paper in Physical Review Letters, scientists around Andreas Elben und Benoît Vermersch from Peter Zoller's group present a new method with which quantum states prepared on different quantum computers or quantum simulators can be compared.

Simon Baier

The experimental physicist Simon Baier from the research group led by Francesca Ferlaino will receive the IQOQI Dissertation Prize 2019, a prize worth 1,000 euros, which will be awarded for the sixth time this year and honors scientific excellence in the field of quantum physics.

Several tens of thousands of particles spontaneously organize in a self-determined crystalline structure while sharing the same macroscopic wavefunction - hallmarks of supersolidity.

The Physics magazine of the American Physical Society (APS) has named the discovery of supersolidity in ultracold quantum gases as one of the top ten highlights of 2019. The research group led by Francesca Ferlaino has for the first time obtained evidence of supersolidity in erbium and dysprosium gases. Similar experiments were conducted in Pisa and Stuttgart.
