  1. The strongest permanent magnets today contain a mix of the elements neodymium and iron. However, neodymium on its own does not behave like any known magnet, confounding researchers for more than a half-century. Physicists at Radboud University and Uppsala University have shown that neodymium behaves like a self-induced spin glass, meaning that it is composed of a rippled sea of many tiny whirling magnets circulating at different speeds and constantly evolving over time. Understanding this new type of magnetic behaviour refines our understanding of elements on the periodic table, and could eventually pave the way for new materials for artificial intelligence. The results will be published on 29th of May, in Science.
  2. Researchers at the University of Science and Technology of China have recently introduced a new satellite-based quantum-secure time transfer (QSTT) protocol that could enable more secure communications between different satellites or other technology in space. Their protocol, presented in a paper published in Nature Physics, is based on two-way quantum key distribution in free space, a technique to encrypt communications between different devices.
  3. To simulate in a laboratory what happens in particle accelerators has been an ambitious goal in the study of the fundamental forces of nature pursued by high-energy physicists for many years. Now, thanks to research conducted by the groups of statistical physics of SISSA—Scuola Internazionale Superiore di Studi Avanzati and the "Abdus Salam" International Centre for Theoretical Physics (ICTP), that goal is closer to reach.
  4. Researchers at the Center for Quantum Information and Quantum Biology at Osaka University used trapped ions to demonstrate the spreading of vibrational quanta as part of a quantum random walk. This work relies on their exquisite control of individual ions using lasers, and can lead to new quantum simulations of biological systems.
  5. A Chinese joint team has conducted a study and discovered the physical origin of electronic phase separation phenomena in complex oxides.
  6. A physicist has created the fifth state of matter working from home using quantum technology.
  7. Researchers at Delft University of Technology have developed a sensor that is only 11 atoms in size. The sensor is capable of capturing magnetic waves and consists of an antenna, a readout capability, a reset button and a memory unit. The researchers hope to use their atomic sensor to learn more about the behaviour of magnetic waves, so that hopefully such waves can one day be used in green ICT applications.
  8. A scientist at the University of Sydney has achieved what one quantum industry insider has described as "something that many researchers thought was impossible".
  9. A group of Skoltech scientists, in collaboration with colleagues from the University of Southampton (UK), developed a fully optical approach to control the couplings between polariton condensates in optical lattices. This study is an important step toward the practical application of optical polariton condensate lattices as a platform for simulating condensed matter phases. The research results were published in the journal Physical Review Letters, where the paper was featured on the front cover.
  10. Xu Yi, assistant professor of electrical and computer engineering at the University of Virginia, collaborated with Yun-Feng Xiao's group from Peking University and researchers at Caltech to achieve the broadest recorded spectral span in a microcomb.
  11. Researchers at University of Delaware, University of Arizona and Haverford College have recently introduced the idea of searching for scalar dark matter using compact acoustic resonators. Their paper, published in Physical Review Letters, theoretically demonstrates the potential of mechanical systems in searching for dark matter.
  12. In recent years, topology has emerged as an important tool to classify and characterize properties of materials. It has been found that many materials exhibit a number of unusual topological properties, which are unaffected by deformations, e.g., stretching, compressing, or twisting. These topological properties include quantized Hall currents, large magnetoresistance, and surface excitations that are immune to disorder. It is hoped that these properties could be utilized for future technologies, such as, low-power electronics, ultrafast detectors, high-efficiency energy converters, or for quantum computing.
  13. A team of physicists at the University of Bristol has developed the first integrated photon source with the potential to deliver large-scale quantum photonics.
  14. Strong coupling between cavity photon modes and donor/acceptor molecules can form polaritons (hybrid particles made of a photon strongly coupled to an electric dipole) to facilitate selective vibrational energy transfer between molecules in the liquid phase. The process is typically arduous and hampered by weak intermolecular forces. In a new report now published on Science, Bo Xiang, and a team of scientists in materials science, engineering and biochemistry at the University of California, San Diego, U.S., reported a state-of-the-art strategy to engineer strong light-matter coupling. Using pump-probe and two-dimensional (2-D) infrared spectroscopy, Xiang et al. found that strong coupling in the cavity mode enhanced the vibrational energy transfer of two solute molecules. The team increased the energy transfer by increasing the cavity lifetime, suggesting the energy transfer process to be a polaritonic process. This pathway on vibrational energy transfer will open new directions for applications in remote chemistry, vibration polariton condensation and sensing mechanisms.
  15. Physicists at the National Institute of Standards and Technology have boosted their control of the fundamental properties of molecules at the quantum level by linking or "entangling" an electrically charged atom and an electrically charged molecule, showcasing a way to build hybrid quantum information systems that could manipulate, store and transmit different forms of data.
  16. Researchers at the Paul Scherrer Institute PSI have succeeded for the first time in recording a light-driven sodium pump from bacterial cells in action. The findings promise progress in the development of new methods in neurobiology. The researchers used the new X-ray free-electron laser SwissFEL for their investigations. They have published their findings today in the journal Nature.
  17. Scientists are using light waves to accelerate supercurrents and access the unique properties of the quantum world, including forbidden light emissions that one day could be applied to high-speed, quantum computers, communications and other technologies.
  18. Rare-earth minerals are a class of materials with similar properties that are currently used to build a variety of devices, including LEDs, rechargeable batteries, magnets, lasers, and much more. These materials' electron spins can be hosted in crystals, creating systems with unique characteristics that could serve as interfaces between telecom-band photons and long-lived spin quantum bits.
  19. QuTech, a collaboration between TU Delft and TNO, has demonstrated a novel setup for fast turnaround testing and validation of quantum materials and devices. The setup uses ordinary electronic chip components that can operate at extreme cryogenic temperatures, and can be readily integrated in any type of cryostat. The scientists published the details of their setup in an open-access journal npj Quantum Information, allowing research groups worldwide to modify their cryostat and greatly enhance its throughput.
  20. A team of researchers at Heidelberg University has succeeded in building an apparatus that allowed them to observe Pauli crystals for the first time. They have written a paper describing their efforts and have uploaded it to the arXiv preprint server.
