Synthesized with Laser Light

Using intense pulses of laser light, members of the attoworld team at the Max Planck Institute for Quantum Optics and the Ludwig-Maximilian University have synthesized trihydrogen ions from water molecules adsorbed onto nanoparticles.

Probing the Dynamics of Photoemission

Physicists at the Max Planck Institute for Quantum Optics (MPQ) and Ludwig-Maximilian University in Munich (LMU) have used ultrashort laser pulses to probe the dynamics of photoelectron emission in tungsten crystals.

New boost in quantum technologies

Researchers at the University of Stuttgart were able to detect qubits in two-dimensional materials for the first time.  Quantum computers or quantum sensors consist of materials that are completely different to their classical predecessors. These […]

When memory qubits and photons get entangled

Scientists at the University of Bonn have been able for the first time to demonstrate quantum entanglement between a stationary qubit, i.e. a two-state quantum system, and a photon with direct coupling to an optical […]

Quantum Processor made in Germany

An alliance between Forschungszentrum Jülich and the semiconductor manufacturer Infineon, together with institutes of the Fraunhofer-Gesellschaft (IAF, IPMS) as well as the Leibniz Association (IHP, IKZ), the universities of Regensburg and Konstanz and the quantum start-up HQS aims to build a semiconductor quantum processor made in Germany that is based on the “shuttling” of electrons and is to be achieved with technology available in Germany.

Direct observation of the Pauli principle

Direct observation of the Pauli principle

Researchers at Heidelberg University‘s Physics Institute have recently observed the Pauli principle directly in a continuous system comprised of up to six particles. Their experiment could pave the way towards a better understanding of strongly interacting systems comprised of fermions.

Quantum systems learn joint computing

Today’s quantum computers contain up to several dozen memory and processing units, the so-called qubits. Researchers from MPQ have successfully interconnected two such qubits located in different labs to a distributed quantum computer. Their system […]
