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.

In their paper, the researchers outline a new strategy for generating spin-squeezed entanglement. They intuited, and together with collaborators in France quickly confirmed via experiment that the ingredients for spin squeezing are present in a ubiquitous type of magnetism found often in nature — ferromagnetism, which is also the force that makes refrigerator magnets stick. They posit that all-to-all interactions are not necessary to achieve spin squeezing, but rather, so long as the spins are connected well enough to sync into a magnetic state, they should also be able to dynamically generate spin squeezing.

Scientists from the National University of Singapore (NUS) have shown that excitonic resonances and transitions between excitons can significantly increase the efficiency of generating entangled photon pairs. This could lead to the development of efficient ultrathin quantum light sources.

A research group led by scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory has uncovered details about the formation and behavior of mobile, microscopic, particle-like objects called “excitons” in a class of materials known as van der Waals magnets.

A research team led by Prof PENG Xinhua and Associate Prof. JIANG Min from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) has discovered the Fano resonance interference effect between mixed atomic spins. They proposed a novel magnetic noise suppression technique, reducing magnetic noise interference by at least two orders of magnitude. The study was published in Physical Review Letters.

Bruker Corporation is pleased to announce the successful installation and acceptance of a 1.2 GHz Avance Nuclear Magnetic Resonance (NMR) spectrometer at the Korea Basic Science Institute ( KBSI ), just in time before the start of the ICMRBS 2024 conference in Korea. As the first 1.2 GHz NMR system in the Asia-Pacific region, it sets a new benchmark for molecular, cell biology and disease research by ultra-high field NMR.

Scientists from the University of Warsaw (UW) is Faculty of Physics in collaboration with other researchers from Poland as well as Italy, Iceland, and Australia, have demonstrated the creation of perovskite crystals with predefined shapes that can serve in nonlinear photonics as waveguides, couplers, splitters, and modulators. The research results were published in “Nature Materials”.

The work, originating from ultrathin materials, could impact future electronics and establishes a new way to study these particles through a powerful instrument at the Brookhaven National Laboratory.

SandboxAQ announced today the signing of two agreements with the U.S. Army: one with the Command, Control, Communications, Computers, Cyber, Intelligence, Surveillance and Reconnaissance Center (C5ISR Center) and the second with the Combat Capabilities Development Command’s (DEVCOM) Ground Vehicle Systems Center (GVSC).

Scientists at the U.S. Department of Energy’s Fermi National Accelerator Laboratory and University of Chicago reported the ability to enhance the signals from dark matter waves by a factor of 2.78 using novel quantum techniques. This technology demonstrates how advances in quantum information science can be applied, not only to quantum computing applications, but also to new physics discoveries.
