Quantum reservoir computing peaks at the edge of many-body chaos, study suggests

Reservoir computing is a promising machine learning-based approach for the analysis of data that changes over time, such as weather patterns, recorded speech or stock market trends. Classical reservoir computing techniques are known to perform best at the “edge of chaos,” or in simpler terms, at a “sweet spot” in which the behavior of systems is neither entirely predictable (i.e., order) nor completely unpredictable (i.e., chaos).

In recent years, some physicists and quantum engineers have been exploring the possibility of realizing a quantum equivalent of classical reservoir computing, known as quantum reservoir computing (QRC). These approaches enable the processing of temporal data and the prediction of events unfolding over time, leveraging high-dimensional quantum states.

Researchers at the University of Tokyo carried out a study investigating how QRC would behave when applied to complex quantum many-body systems, which consist of several interacting quantum particles. Their paper, published in Physical Review Letters, introduces a physics-based framework that could inform the future development of QRC systems.

Engineered nanoparticles could deliver better targeted cancer treatment to lymph nodes

Scientists at McGill University and the Rosalind and Morris Goodman Cancer Institute have developed a new way to deliver cancer immunotherapy that caused fewer side effects compared to standard treatment in a preclinical study. The work is published in the journal Proceedings of the National Academy of Sciences.

The experimental approach is designed to treat cancer that has spread to the lymph nodes, a difficult-to-treat stage of the disease. Today, most immunotherapies are delivered by intravenous (IV) infusion and circulate throughout the body. This can trigger immune responses in healthy tissues, leading to serious side effects.

“Some immunotherapies cause such severe side effects that clinicians are forced to lower the dose, making treatment less effective,” said senior author Guojun Chen, Assistant Professor in McGill’s Department of Biomedical Engineering and member of the Goodman Cancer Institute. “Our approach could allow for higher, more effective doses while limiting toxicity, which is a major goal in cancer treatment.”

‘All-in-one,’ single-atom could power both sides of water splitting

Green hydrogen production technology, which utilizes renewable energy to produce eco-friendly hydrogen without carbon emissions, is gaining attention as a core technology for addressing global warming. Green hydrogen is produced through electrolysis, a process that separates hydrogen and oxygen by applying electrical energy to water, requiring low-cost, high-efficiency, high-performance catalysts.

A research team led by Dr. Na Jongbeom and Dr. Kim Jong Min from Korea Institute of Science and Technology’s Center for Extreme Materials Research has developed next-generation water electrolysis catalyst technology. This technology integrates a single-atom “All-in-one” catalyst precisely controlled down to the atomic level with binder-free electrode technology. The study is published in the journal Advanced Energy Materials.

A key feature of this technology is its ability to stably perform both hydrogen evolution and oxygen evolution reactions simultaneously on a single electrode.

Nanotubes unlock new wavelengths for smarter sensing

Sensors made of carbon nanotubes that can measure infrared and terahertz radiation are being tested for uses ranging from detecting damaged cables after earthquakes, to collecting health data via ultrathin wearable devices, and assisting with pharmaceutical quality control, say researchers in Japan.

“Accurately visualizing the internal structures of organisms and objects is integral to our daily lives, from medical imaging to security scanning in airports,” and terahertz sensors built from carbon nanotubes are uniquely suited to this purpose, says Yukio Kawano is a professor of engineering at Chuo University in Tokyo, and project leader at the Kanagawa Institute of Industrial Science and Technology (KISTEC) in Japan.

Compared with many sensor technologies that can only detect one part of the electromagnetic spectrum, Kawano’s team is working to create sensors that can detect terahertz and a broader range of radiation, and use them to produce high-resolution images.
