Quantum computers still face a major hurdle on their pathway to practical use cases: their limited ability to correct the arising computational errors. To develop truly reliable quantum computers, researchers must be able to simulate quantum computations using conventional computers to verify their correctness – a vital yet extraordinarily difficult task. Now, in a world-first, researchers from Chalmers University of Technology in Sweden, the University of Milan, the University of Granada, and the University of Tokyo have unveiled a method for simulating specific types of error-corrected quantum computations – a significant leap forward in the quest for robust quantum technologies.

The entrepreneurial ecosystems (EE) approach is often promoted for Africa’s growth, but Africa already has many entrepreneurs. Instead of increasing entrepreneurship, researchers argue for strategies drawn from East Asia’s development and Schumpeterian growth theory—both of which oppose EE thinking. These approaches suggest that Africa should focus on building large, productive firms and absorbing existing technologies, rather than relying on start-ups, to achieve long-term, sustainable economic development.

New research reveals a surprising geometric link between human and machine learning. A mathematical property called convexity may help explain how brains and algorithms form concepts and make sense of the world.

A groundbreaking study reveals how strain rate influences anthracite crack characteristic Sstress under dynamic loading, offering a predictive model to assess crack stress thresholds. This research provides critical insights into damage evolution mechanisms, advancing strategies to predict and mitigate catastrophic events like rock bursts in underground mining.
