Researchers from the Cluster of Excellence ct.qmat have developed a method to model a central theory of quantum gravity in the laboratory. Their goal: to decipher previously unexplained phenomena in the quantum world.

BQP, a startup leading the development of quantum-based engineering simulations, today announced a significant research milestone for simulating Computational Fluid Dynamics (CFD). The milestone was achieved using a hybrid quantum-classical solver, which is part of BQP’s next-gen simulation platform, BQPhy.

Now, in a recently published Nature paper, JILA and NIST Fellow and University of Colorado Boulder Physics Professor Jun Ye and his team, along with collaborators in Mikhail Lukin’s group at Harvard University, used periodic microwave pulses in a process known as Floquet engineering, to tune interactions between ultracold potassium-rubidium molecules in a system appropriate for studying fundamental magnetic systems. Moreover, the researchers observed two-axis twisting dynamics within their system, which can generate entangled states for enhanced quantum sensing in the future.

A research team led by Professor Monika Aidelsburger and Professor Immanuel Bloch from the LMU Faculty of Physics has investigated this question concerning quantum many-body systems and found indications that they can be described macroscopically through simple diffusion equations with random noise. The study was recently published in the journal Nature Physics.

Chunyu Guo, group leader in the Department for Microstructured Quantum Matter at the MPSD, has been awarded a Starting Grant by the European Research Council (ERC) for his Free-Kagome project. He will investigate the novel effects of electronic correlations in the recently discovered AV3Sb5 family of Kagome superconductors using a sophisticated framework that isolates the samples from external influences and makes it possible to control them with extremely high precision.

Researchers from Skoltech, Universitat Politècnica de València, Institute of Spectroscopy of RAS, University of Warsaw, and University of Iceland have demonstrated the spontaneous formation and synchronization of multiple quantum vortices in optically excited semiconductor microcavities.

Although systems consisting of many interacting small particles can be highly complex and chaotic, some can nonetheless be described using simple theories. Does this also pertain to the world of quantum physics? A research team led by Professor Monika Aidelsburger and Professor Immanuel Bloch from the LMU Faculty of Physics investigated this question concerning quantum many-body systems and found indications that they can be described macroscopically through simple diffusion equations with random noise. The study was recently published in the journal Nature Physics.

Scientists at EPFL, the Helmholtz-Zentrum Berlin and Freie Universität Berlin have uncovered intriguing insights into the magnetic properties of a complex material that dances on the edge of quantum spin liquid behavior. The discovery could have far-reaching implications for our understanding of quantum materials and their potential technological applications.

In the past year, the National Energy Research Scientific Computing Center (NERSC) has teamed up with the Boston-based quantum computing company QuEra Computing, exploring one up-and-coming approach to quantum computing known as neutral-atom technology. After a successful first year punctuated with strong scientific results, the partnership has been extended, with plans to offer neutral-atom quantum computing access to some users in the coming year.

Researchers at the Max Planck Institute for Nuclear Physics in Heidelberg have succeeded in selectively manipulating the motion of the electron pair in the hydrogen molecule. The emission direction of a photoelectron released by light (a photon) relative to the remaining bound electron in the cleaved neutral hydrogen atom can be controlled by the time interval between two laser flashes on the scale of a few hundred attoseconds (10–18 s). The adjustable emission asymmetry is based on the quantum entanglement between the bound electron and the spatially separated emitted electron.
