It would be difficult to understand the inner workings of a complex machine without ever opening it up, but this is the challenge scientists face when exploring quantum systems. Traditional methods of looking into these systems often require immense resources, making them impractical for large-scale applications.
An atomic clock research team from the National Time Service Center of the Chinese Academy of Sciences has proposed and implemented a compact optical clock based on quantum interference enhanced absorption spectroscopy, which is expected to play an important role in micro-positioning, navigation, timing (μPNT) and other systems.
Researchers at Rice University have developed a new machine learning (ML) algorithm that excels at interpreting the "light signatures" (optical spectra) of molecules, materials and disease biomarkers, potentially enabling faster and more precise medical diagnoses and sample analysis.
Researchers have demonstrated a new quantum sensing technique that widely surpasses conventional methods, potentially accelerating advances in fields ranging from medical imaging to foundational physics research, as shown in a study published in Nature Communications.
The beloved Italian pasta cacio e pepe is perhaps best known for two things: being delicious and being frustratingly difficult to cook. At first glance, it looks like a simple recipe, containing only three ingredients: pasta, pecorino romano cheese, and black pepper. But as anyone who has tried to make it will know, the cheese will often clump when added to the hot pasta water, turning what is supposed to be a smooth, creamy sauce into a stringy, sticky mess.
A research team from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has developed a novel large-scale compound cryopump (multi-stage cryopump) capable of separating fuel particles from helium ash.
Exotic nuclei near and beyond the proton drip line exhibit a range of unique decay processes, including β-delayed proton emission, α decay, and direct proton radioactivity. Spectroscopic studies utilizing high-efficiency, low-threshold detection systems have become essential for exploring the intricate properties of these nuclei.
In the future, quantum computers could rapidly simulate new materials or help scientists develop faster machine‐learning models, opening the door to many new possibilities.
Drying droplets have fascinated scientists for decades. From water to coffee to paint, these everyday fluids leave behind intricate patterns as they evaporate. But blood is far more complex—a colloidal suspension packed with red blood cells, plasma proteins, salts, and countless biomolecules.
Picture yourself at a busy pedestrian crossing. When the light is red, everyone waits—until one person starts to cross. Soon, others follow, and eventually everyone follows the crowd and crosses. Amsterdam physicists have discovered that a very similar process happens at the microscopic level, when two touching surfaces start to slide. Their results were published in Physical Review Letters this week.
Recently, a research team achieved real-time tracking of electronic/magnetic structure evolution in Li-rich Mn-based materials during the initial cycling through the self-developed operando magnetism characterization device.
Recently, a group of researchers discovered a novel way to achieve spin-valve effects using kagome quantum magnets.
In a landmark achievement for fusion energy, ITER has completed all components for the world's largest, most powerful pulsed superconducting electromagnet system.
Swinburne researchers have discovered unexpected and entirely new quantum behaviors that only occur in one-dimensional systems, such as electrical current. Their new paper, published in Physical Review Letters, explores a fundamental question in quantum physics: what happens when a single "impurity" particle, such as an atom or electron, is introduced into a tightly packed crowd of identical particles.
A research team from Skoltech and the University of Wuppertal in Germany determined that an all-optical universal logic gate that was previously developed at Skoltech can operate at a speed of 240 GHz at room temperature.
