Quantum physics has allowed for the creation of sensors far surpassing the precision of classical devices. Now, several studies in Nature show that the precision of these quantum sensors can be significantly improved using entanglement produced by finite-range interactions. Innsbruck researchers led by Christian Roos were able to demonstrate this enhancement using entangled ion-chains with up to 51 particles.
During the World of Photonics Congress in Munich, Rainer Blatt was presented with the Herbert Walther Prize 2023. He received the award for his outstanding contributions to quantum optics and quantum information as well as his leading role in advancing this research field.
A quarter of a century ago, theoretical physicists at the University of Innsbruck made the first proposal on how to transmit quantum information via quantum repeaters over long distances which would open the door to the construction of a worldwide quantum information network. Now, a new generation of Innsbruck researchers has built a quantum repeater node for the standard wavelength of telecommunication networks and transmitted quantum information over tens of kilometers.
PASQuanS2 aims to develop next-generation programmable, large-scale atomic quantum simulators operating with up to 10,000 atoms building on the successful European Quantum Flagship project PASQuanS and unites 25 academic and technology partners from Austria, France, Germany, Italy, Slovenia and Spain, among them the University of Innsbruck, IQOQI and the Spin-offs AQT und ParityQC.
