Quantum physicists achieve entanglement record
10.04.2018
Entanglement is of central importance for the new quantum technologies of the 21st century. A German-Austrian research team is now presenting the largest entangled quantum register of individually controllable systems to date, consisting of a total of 20 quantum bits. The physicists in Innsbruck, Vienna and Ulm are pushing experimental and theoretical methods to the limits of what is currently possible. Read more: Quantum...

Two-toned light pattern creates steep quantum walls for atoms
14.03.2018
A new landscape promises to bring ultracold atomic neighbors closer than ever before. A corresponding concept was recently published by a team of scientists from the Joint Quantum Institute (JQI) and the Institute of Quantum Optics and Quantum Information (IQOQI). Read more: Two-toned...

Roton quasiparticles observed in quantum gas
05.03.2018
An Innsbruck team of experimental physicists, in collaboration with theorists from Innsbruck and Hannover, has for the first time observed so-called roton quasiparticles in a quantum gas. Empirically introduced by Landau to explain the bizarre properties of superfluid liquid Helium, these quasiparticles reflect an "energy softening" in the system as precursor of a crystallization instability. The new work published in Nature Physics demonstrate similar phenomena in the quantum-gas phase thanks to magnetic interactions, paving the way for a novel understanding of paradigmatic states of quantum fluids, such as supersolids.
