Quantum simulators promise to study intricate quantum phases of matter. Of those, topological phases are among the most interesting, not the least for their potential applications in quantum computing, but also from the perspective of condensed matter physics. So far, intrinsic topological order has been...
In PASQuanS, alongside the actual development of the quantum simulators, we develop and exploit novel classical numerical methods to benchmark the future quantum simulations and establish the quantum advantage threshold, that is, the border of the physically relevant phenomena that can be classically simulated. One...
One of the most intriguing applications of quantum simulators developed in PASQuanS is their application to the study of lattice gauge theories. Lattice gauge theories describe the physics of highly diverse and fundamental phenomena, ranging from the Standard Model that describes the fundamental constituents of our...
The performance of quantum technologies significantly depends on the duration over which the apparatus can be run. Rydberg-based quantum technologies, in particular, already rely on the particularly long lifetime of Rydberg atoms, in conjunction with the strength of their mutual interactions. They could see their...
Topological materials attract great interest and may provide the basis for a new era in materials development. In Science Advances, physicists around Andreas Elben, Jinlong Yu, Peter Zoller and Benoit Vermersch now present a new measuring method that allows to identify and characterize so-called topological...
For the first time, physicists of Kastler Brossel Laboratory have been able to use light to trap giant atoms, so-called circular Rydberg atoms. This work will push the limits of currently developed quantum technologies that use these atoms of remarkable properties. Rydberg atoms have proved particularly...
Antoine Browaeys from our PASQuanS Partner Institut d´Optique has participated in a television report on quantum computers on the French TV channel “France 3”. The broadcast presents quantum computers as the next major revolution in information technology. It was partly filmed in the laboratories of...
Physicists at the University of Innsbruck are proposing a new model that could demonstrate the supremacy of quantum computers over classical supercomputers in solving optimization problems. In a recent paper, they demonstrate that just a few quantum particles would be sufficient to solve the mathematically...
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...
In the article TÜV für die Zukunftstechnik the Berliner Tagesspiegel reports on Jens Eisert`s work as a Partner of PASQuanS. Eisert explains, in how far Quantum Simulation contributes to the construction...
