Quantum one-way street in topological insulator nanowires
Quantum one-way street in topological insulator nanowires Very thin wires made of a topological insulator could enable highly stable qubits, the building blocks of future quantum computers. Scientists see a new result in topological insulator devices as an important...
Quantum Computing challenged by disorder – study published in Nature Communications
Research conducted in the ML4Q groups of Simon Trebst, Alex Altland and David DiVincenzo analyzed cutting edge device structures to demonstrate that some of them are indeed operating dangerously close to a threshold of chaotic meltdown. The challenge is to walk a thin...
ML4Q&A with Beata Kardynal
We continue to feature some of our experimental physicists. In this episode, we talk to Beata Kardynal, group leader at Forschungszentrum Jülich and at RWTH Aachen. We discuss her career and her training in electronic devices to using these devices to couple to...
First Hybrid Quantum Bit Based on Topological Insulators
First Hybrid Quantum Bit Based on Topological Insulators Scientists at Forschungszentrum Jülich take an important step on the path towards topological quantum computers With their superior properties, topological qubits could help achieve a...
QuantumGuide: Simon Stellmer coordinates newly funded QuantERA project
1.5 million euros for improved quantum sensors Physicists at the University of Bonn lead a new European QuantERA collaborative project They originate from the world of the smallest particles and have the ability to measure things with the highest...
2D materials for next generation computing
In a compact comment published in Nature Communications, Max Lemme, Christoph Stampfer and colleagues outline the most promising fields of applications of two-dimensional (2D) materials, as well as the challenges that still need to be solved to see the appearance of...
Inter-site collaboration demonstrates wavelength conversion of single photons emitted by semiconductor quantum dots
Inter-site collaboration demonstrates wavelength conversion of single photons emitted by semiconductor quantum dots ML4Q researchers from Bonn and Jülich have published recent results in Optics Letters on wavelength conversion at the single-photon level - a...
Extremely compressible “gas of light”
Busley et al. bring these advantages to quantum gases of light and explore a textbook scenario: a two-dimensional, spatially uniform gas of bosons.[from Photons think inside the box, Perspective, Science 375 (6586), pp. 1355-1356, 2022]The group of Martin Weitz...
The Wilhelm and Elsa Heraeus Dissertation Prize goes to Federico Grasselli from the Bruß group
Since 2018, Heinrich Heine University Düsseldorf (HHU) and Bergische Universität Wuppertal (BUW) have been awarding the "Wilhelm and Else Heraeus Dissertation Prize" which is endowed with 4000 euros. ML4Q associated member Federico Grasselli received the award for...
