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

Researchers led by Francesca Ferlaino from the University of Innsbruck and the Austrian Academy of Sciences report in Physical Review X on the observation of supersolid behavior in dipolar quantum gases of erbium and dysprosium. In the dysprosium gas these properties are unprecedentedly long-lived. This sets the stage for future investigations into the nature of this exotic phase of matter.


Through randomly selected measurements, Austrian physicists can determine the quantum entanglement of many-particle systems. With the newly developed method, quantum simulations can be extended to a larger number of quantum particles. In the Science Magazine, the researchers report on the first successful demonstration of this method developed by physicists from Innsbruck, Austria.

In a quantum simulator, an international team of researchers was able to investigate the properties of different quantum phase transitions. Due to the complexity of the processes, these dynamics were not experimentally accessible until now. The researchers report their findings in the journal Nature.

A localization phenomenon boosts the accuracy of solving quantum many-body problems with quantum computers which are otherwise challenging for conventional computers. This brings such digital quantum simulation within reach on quantum devices available today.


Last year marked the 20th birthday of a remarkable paper that has changed the entire field of quantum physics. Experimental physicist Immanuel Bloch describes the significance of this paper by Dieter Jaksch, Christoph Bruder, Ignacio Cirac, Crispin Gardiner, and Peter Zoller in a recent review in Nature Physics.
