Researchers submitted a paper exploring microwave phase noise's impact on nitrogen vacancy (NV) sensors. They developed numerical models and experimental methods, including two-point gradiometry, achieving significant phase noise suppression, crucial for high-precision NV-based measurements in magnetometry and spectroscopy.
Researchers at Washington University in St. Louis, led by Jian Wang, professor and director of WashU's Center for Aerosol Science and Engineering, Lu Xu, assistant professor in the department of energy, environmental and chemical engineering at WashU's McKelvey School of Engineering, and scientists from NASA, NOAA, NCA, and European universities, have reportedly discovered something new in the sky: a mechanism that generates a significant amount of the particles in Earth's atmosphere. The study was published in Science.
A new study published in Physics Letters investigated the possibility of incorporating the flavor-related quantum mechanical effects into the neutrino transport within a neutron star merger remnant through the use of a semi-classical angular moment based method.
Researchers at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility are exploring how adding oxygen to the surfaces of particle accelerator cavities, one of the most critical parts of an accelerator, can help scientists custom-tailor their properties for maximum efficiency and minimum cost.
This study explores a quantum algorithm based on Quantum Particle Swarm Optimization (QPSO) for maximizing photovoltaic energy production under varying environmental conditions. Compared to classical methods, the quantum approach shows superior performance in scenarios like partial shading and high temperatures, demonstrating potential for improved efficiency and reliability in solar energy management.
A research team led by Guangcan Guo from the University of Science and Technology of China along with Professors from the University of Hong Kong, constructed a coherent superposition of quantum evolution with two opposite directions in a photonic system and confirmed its advantage in characterizing input-output indefiniteness
An international research group led by the Italian National Institute for Astrophysics observed the dramatic interaction between a quasar inside the PJ308–21 system and two massive satellite galaxies in the distant universe using the Near-Infrared Spectrograph on board the James Webb Space Telescope.
Computer-aided drug design, particularly quantum mechanics (QM) methods, offers chemically accurate insights but is limited by computational efficiency, especially for large systems. Researchers summarize recent advances in the application of QM-based methods in bioactive species characterization, structure-guided hit-to-lead optimization, and the identification of molecular features of bioactivity.
A group of researchers from the Pohang University of Science and Technology and the National Institute for Materials Science have successfully controlled the quantum mechanical properties of Andreev-bound states in bilayer graphene-based Josephson junctions using gate voltage.
Researchers in the journal Light: Science & Applications demonstrated chiral behavior in a quantum system without encircling its Liouvillian exceptional points (LEPs). Using a Paul-trapped ion setup, they showed asymmetric mode conversion crucial for quantum thermodynamic cycles, highlighting the role of non-adiabatic processes like the Landau-Zener-Stückelberg phase in chiral state transfer dynamics.
