Quantum physics allows making statements about the behavior of a wide variety of many-particle systems at the atomic level, from salt crystals to neutron stars. In quantum systems, many parameters do not have concrete values but are distributed over various values with certain probabilities. Often...
Quantum Simulation as a solution provider for unsolved problems in information technology, physics and chemistry: PASQuanS Coordinator Immanuel Bloch from the Max Planck Institute of Quantum Optics has given an interview on Quantum Simulation to the computer magazine CHIP 1/2021. You can read the full article...
In a recent article published by the American Physical Society’s Physical Review A, the Atos Quantum Lab (Michel Fabrice Serret, Bertrand Marchand, Thomas Ayral) investigates the potential of Rydberg analog quantum computers (a promising quantum platform constructed for instance at IOGS or at Pasqal) for...
The PASQuanS 2nd Year Meeting was held on 19th of October 2020. Due to the Covid-19 crisis it was not possible to have a live event. In a half-day online meeting, around 60 participants from the PASQuanS consortium and some end users discussed first major...
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...
