In a review in Science, a team led by ERC Synergy Grant awardees Markus Aspelmeyer, Lukas Novotny, Romain Quidant and Oriol Romero-Isart explores the potential of the new research field of levitodynamics. This offers a new experimental platform with unique opportunities for fundamental science and many potential applications such as sensor technology.
Experimental physicist Rudolf Grimm received the BEC Senior Award 2021 last weekend for his groundbreaking work in the field of quantum gases. This award for outstanding achievements in the field of Bose-Einstein condensation was presented at an international conference on quantum gases in Spain.
Quantum computers become ever more powerful, but how can we be sure that the answers they return are accurate? A team of physicists from Vienna, Innsbruck, Oxford, and Singapore solves this problem by letting quantum computers check each other.

Quantum matter can be solid and fluid at the same time – a situation known as supersolidity. Researchers led by Francesca Ferlaino have now created for the first time this fascinating property along two dimensions. They now report in the journal Nature on the realization of supersolidity along two axes of an ultracold quantum gas. The experiment offers many possibilities for further investigation of this exotic state of matter.
Only recently researchers have levitated and cooled nanoparticles into the quantum regime. An Austrian research team led by Oriol Romero-Isart now proposes a way to harness the quantum properties of such particles before they lose them due to decoherence. To this end, the wave function of the particle is repeatedly expanded and compressed in a loop.
