Scientists have developed a groundbreaking on-chip quantum memory platform using 3D-nanoprinted hollow-core waveguides called "light cages" to store flying photons in cesium vapor. This innovative approach achieves storage times of several hundred nanoseconds while enabling multiple quantum memories on a single chip. The technology marks a major advance in spatially multiplexed quantum memories for use in quantum repeaters and photonic quantum computing platforms.

Organised by the Beijing-Hong Kong Academic Exchange Centre, the results of the annual selection for the ‘Top 10 Innovation & Technology News in Hong Kong 2025’, have recently been announced. The University of Hong Kong (HKU) is pleased to report that three of its groundbreaking research projects have made it onto this prestigious list, leading among all local institutions. These selected projects in the fields of medical health and astronomical sciences highlight HKU's strong capabilities in advanced translational research and technology transfer. The university aims to address global challenges and deliver impactful real-world solutions, all while striving to benefit society and support sustainable development.  

A breakthrough in neural sensing technology has been achieved through collaboration between Professor Cai Xinxia's team from the National Key Laboratory of Sensor Technology at the Aerospace Information Research Institute, Chinese Academy of Sciences, and Professor Yu Yanqin's team from Zhejiang University. They have successfully developed a novel triple-electrode integrated multi-channel microelectrode array that enables simultaneous monitoring of neurochemical and electrophysiological signals in freely behaving animals.

A research team led by Professor Leo Tianshuo Zhao from the Department of Electrical and Electronic Engineering at the Faculty of Engineering, University of Hong Kong (HKU), has developed the world’s smallest fully printed infrared photodetectors, which are an innovative room-temperature nano-printing platform that overcomes the limitations of traditional silicon-based technology.

The University of Hong Kong (HKU) and Tsinghua University signed five Memoranda of Understanding (MoUs) on 22 December 2025, expanding their partnership across diverse fields including public health, engineering, law, and astronomy, further strengthening the partnership between the two institutions in academic research and talent development.

A study led by researchers at the Department of Civil Engineering at The University of Hong Kong (HKU) has uncovered alarming evidence that soil worldwide is emerging as a significant reservoir and amplifier of high-risk antibiotic resistance genes (ARGs), which enable bacteria to develop resistance to antibiotics, and that their threat to public health has continued to increase over the past decade or so.
