For the first time, Oak Ridge National Laboratory (ORNL) will run equipment developed at its research facilities on a commercially available quantum network at EPB Quantum Network powered by Qubitekk. Starting this month, ORNL is testing its Automatic Polarization Compensation (APC), a key technology needed to convey quantum data across a network while maintaining all its complexities and probabilities.

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.

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.

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.

A team of researchers at EPFL, led by Prof. Tobias Kippenberg, in collaboration with Prof. Sunil Bhave's group at Purdue University, has achieved a key step in interfacing microwave superconducting circuits with optical photons, which could overcome critical challenges in scaling up these systems for next-generation computing.

In a scientific breakthrough, an international research team from Korea's IBS Center for Quantum Nanoscience (QNS) and Germany's Forschungszentrum Jülich developed a quantum sensor capable of detecting minute magnetic fields at the atomic length scale. This pioneering work realizes a long-held dream of scientists: an MRI-like tool for quantum materials.

Now, researchers at the University of Chicago’s Pritzker School of Molecular Engineering (PME) have discovered how to combine two powerful technologies—trapped atom arrays and photonic devices—to yield advanced systems for quantum computing, simulation and networking. The new combination will allow the construction of large quantum systems which can be easily scaled up, by leveraging photonics to interconnect individual atom arrays.

Researchers at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and several collaborating institutions have successfully demonstrated an innovative approach to find breakthrough materials for quantum applications. The approach uses rapid computing methods to predict the properties of hundreds of materials, identifying short lists of the most promising ones. Then, precise fabrication methods are used to make the short-list materials and further evaluate their properties.

ICFO researchers have obtained a world record degree of indistinguishability between two photons coming from two dissimilar quantum nodes when no detections are discarded. These results pave the way towards future heterogeneous quantum networks.
