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.
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.
