New Progress in First-Principles Quantum Computing for Nuclear Structure

New Progress in First-Principles Quantum Computing for Nuclear Structure

Recently, the research team at the Institute of Modern Physics, Chinese Academy of Sciences, has made new progress in quantum computing studies of first-principles nuclear structure for multi-fermion systems. The team developed a universal quantum-classical hybrid computing framework capable of calculating Green's functions and spectral functions of nuclear many-body systems. The relevant results were published as a Letter in Physical Review C. First-principles Hamiltonian many-body calculations are a core approach for revealing the laws of strongly correlated quantum systems, widely applied in fields such as quantum chemistry and nuclear physics. However, the Hilbert space of such problems grows exponentially with particle number, posing insurmountable computational resource challenges on classical computers...

New Progress in Ion Dynamics Regulation in Nanofluidic Memristors by the Institute of Modern Physics, Chinese Academy of Sciences

New Progress in Ion Dynamics Regulation in Nanofluidic Memristors by the Institute of Modern Physics, Chinese Academy of Sciences

Water-based nanofluidic ionic devices offer unique advantages in frontier fields such as brain-computer interfaces and biocompatible computing. Recently, the research team from the State Key Laboratory of Heavy Ion Science and Technology at the Institute of Modern Physics, Chinese Academy of Sciences, in collaboration with Lanzhou University, Hebei University of Geosciences, and other partners, successfully achieved stable ionic memristive effects in single-ion-track nanochannels. Through precise regulation, they realized programmable transitions in memristive and synaptic functions, providing a new technological pathway for the development of next-generation low-power neuromorphic computing hardware. The related results were published in the journal *Small* on July 22. Leveraging the Heavy Ion Research Facility in Lanzhou (HIRFL), the researchers...

Progress and Cost Performance Management of the ITER Project Enhancement

Progress and Cost Performance Management of the ITER Project Enhancement

The ITER Organization reported on July 29 that, regarding the construction progress and cost control of the International Thermonuclear Experimental Reactor (ITER), the project team has established a more detailed monthly tracking mechanism, and regularly reports key performance indicators, updated estimates at completion, and milestone trend analyses to the ITER Council. The ITER project is large in scale with complex interfaces; management efforts involve not only overall schedule and budget but also continuous assessment of thousands of activities including design, manufacturing, component installation, commissioning, and operational readiness. For tasks on the critical path, even delays of a few weeks can have cascading effects on multiple construction work packages. To identify...

After 25 Years, the Muon Wobble Puzzle Sees Key New Progress in Physics

After 25 Years, the Muon Wobble Puzzle Sees Key New Progress in Physics

For 25 years, precise measurements of how muons wobble in a magnetic field have been a major puzzle in particle physics. Early experiments showed a discrepancy between the measured value of the muon's g-factor and theoretical predictions, a difference once seen as a possible hint of unknown particles. Recent new theoretical calculations and experimental analyses have brought a new twist to this puzzle. The muon is a heavier cousin of the electron that precesses like a tiny magnet in a magnetic field. Its extra wobble is quantified by the muon g-2 coefficient. According to quantum theory, known particles and interactions influence this coefficient through fleeting quantum fluctuations, making muon g-2 a key test of the Standard Model...

U.S. Department of Energy Highlights Progress in Legacy Waste Cleanup and Medical Isotope R&D

U.S. Department of Energy Highlights Progress in Legacy Waste Cleanup and Medical Isotope R&D

Recently, senior officials from the U.S. Department of Energy attended an event hosted by the U.S. House Nuclear Cleanup Caucus, presenting the application progress of legacy nuclear waste cleanup efforts in medical isotope R&D and future energy technologies. The event, themed "DOE's Isotope Mission: Legacy Cleanup Saves Lives, Empowers America's Future," focused on how nuclear cleanup missions align with isotope production and medical research. DOE's Under Secretary for Science Dario Gil, along with Oak Ridge National Laboratory Environmental Management Office Manager Eric Olds and Savannah River Operations Office Manager Edwin DeShon, jointly attended the event. DeShon...

Follow-up consultations on ROK-US nuclear-powered submarine and nuclear cooperation agreement progress slowly

Follow-up consultations on ROK-US nuclear-powered submarine and nuclear cooperation agreement progress slowly

According to a South Korean diplomatic source on July 31, South Korea and the United States have yet to finalize the schedule for the second working-level consultation, and the follow-up talks originally planned for July have not yet taken place. The consultations are aimed at implementing the security-related agreements outlined in the joint statement issued at last year's summit between the two countries, including South Korea's introduction of nuclear-powered submarines and the revision of nuclear cooperation arrangements regarding uranium enrichment and spent nuclear fuel reprocessing. The two sides previously held their first working-level consultation in Seoul on the 2nd and 3rd of last month. U.S. Under Secretary of State for Political Affairs Allison Hooker led a cross-agency delegation to South Korea at the time to discuss the implementation of the security agreement with the South Korean side. Observers...

Progress in Russia's Khilonduevskoye Uranium Deposit Development: 3 Kilometers of Mine Workings Completed Ahead of Schedule

Progress in Russia's Khilonduevskoye Uranium Deposit Development: 3 Kilometers of Mine Workings Completed Ahead of Schedule

The mining division of Russia's Rosatom recently announced that underground mining crews completed three kilometers of mine workings ahead of schedule during the development of the Khilonduevskoye deposit. This milestone, originally planned for completion on August 10, was achieved by a team of workers from the Priargunsky Industrial Mining and Chemical Union (PIMCU), which is part of Rosatom Nedra. According to PIMCU, this mine connection will significantly optimize the ventilation system at the fourth level of the Khilonduevskoye deposit and improve the efficiency of rock block loading, laying the foundation for subsequent development work. The company's CEO, Ivan Kiselev, stated that this connection is of critical importance to the company, as it not only links two sections of the mine but also fundamentally transforms the logistics and safety of fourth-level operations.

Hoisting in Place! Global Largest "Artificial Sun" Core Module Installation Progress Exceeds Two-Thirds

Hoisting in Place! Global Largest "Artificial Sun" Core Module Installation Progress Exceeds Two-Thirds

On July 28, local time in France, the sixth vacuum vessel module of the International Thermonuclear Experimental Reactor (ITER) tokamak device—Sector Module 1—successfully completed its overall hoisting and precise positioning. Thus, the assembly progress of ITER vacuum vessel modules has exceeded two-thirds. As the general assembly enters a new phase of multi-disciplinary cross-construction, the China Nuclear Engineering Consortium led the coordination of the international team to successfully complete this critical hoisting, laying a solid foundation for subsequent assembly tasks, while fully demonstrating the cross-cultural project management and overall coordination capabilities of the Chinese team in international mega-science projects. The vacuum vessel is a core component of the tokamak device, consisting of nine large sector modules installed and connected sequentially,...
