A team of physicists has announced a major milestone in quantum information technology: a Raman‑based quantum memory that operates with almost 100 % efficiency. In simple terms, the device can store and retrieve single photons—the fundamental carriers of quantum data—without losing their delicate quantum properties. This near‑unity performance is a huge step forward because previous quantum memories suffered from significant loss, limiting their usefulness in real‑world quantum networks. The researchers achieved this feat by fine‑tuning the interaction between light and a specially prepared atomic medium, allowing the photon’s quantum state to be mapped onto the atoms and later released on demand. The experiment demonstrated not only high storage efficiency but also long coherence times, meaning the stored information remains intact for a useful duration. Looking ahead, the team plans to explore new physics‑driven approaches to further boost performance and to integrate the memory into quantum repeaters—devices that will extend the reach of quantum communication across continents. Ultimately, this technology could underpin fault‑tolerant quantum computers and a global quantum internet, bringing the promise of ultra‑secure communication and unprecedented computational power closer to reality.

By arranging microscopic structures in a precise pattern, the material creates pathways that guide electrons while directing thermal energy away from hot spots. This dual‑control capability promises smarter electronics, improved cooling systems for computers, and more efficient power grids. Researchers demonstrated the concept in lab tests, showing that the material can dynamically switch between conducting electricity and insulating heat, opening doors to adaptive technologies that respond to real‑time conditions. The discovery marks a significant step toward next‑generation multifunctional materials that blend electrical and thermal management in a single, lightweight platform.

The film, only a few nanometers thick, can modulate light with unprecedented speed and efficiency when cooled to near absolute zero, making it ideal for high‑precision sensors and quantum communication devices. By optimizing the deposition process and crystal orientation, the team achieved a dramatic reduction in energy loss, allowing the material to respond to electric fields with minimal delay. This advancement could lead to faster, more reliable optical switches in quantum networks and improve the sensitivity of detectors used in fundamental physics experiments. The discovery underscores the growing importance of engineered materials in pushing the limits of low‑temperature photonics.
Read moreThe 2025 China Robot Industry Development Conference kicked off in Shanghai on November 10, showcasing a milestone for the nation’s robotics sector: China now controls the entire manufacturing chain for humanoid robots, from core components to finished machines. According to a new industry report, China’s embodied‑intelligence market is projected to hit roughly 53 billion yuan this year, representing about 27 % of the worldwide market. Even more striking, the domestic humanoid‑robot segment could reach 82 billion yuan, or half of global sales. Analysts say this surge is driven by rapid technological breakthroughs, supportive government policies, and a growing ecosystem of suppliers, software firms, and end‑users. Capital is flowing fast, and listed companies are reshaping their strategies to capture new opportunities across the value chain. The consensus is that China is entering a systematic upgrade phase, with strong momentum that could cement its position as the world’s leading robotics hub. As embodied‑intelligence moves from labs to commercial applications, the convergence of finance and technology is expected to accelerate product roll‑outs, create jobs, and reshape industries ranging from manufacturing to healthcare.
