RIKEN’s Success Paves Way to Vision of Large-Scale Quantum Computer Within 10 Years
Quantum entanglement of three spin qubits demonstrated in silicon A three-qubit entangled state has been realized in a fully controllable array of spin qubits in silicon Figure 1: False-colored scanning electron micrograph of the device. The purple and green structures represent the aluminium gates. Six RIKEN physicists succeeded in entangling three silicon-based spin qubits using […]
Give It Up! Are You Quantum or Not? South Africa’s Quantum Academia Cracks the Code
Isaac Nape, an emerging South African talent in the study of quantum optics, is part of a crack team of Wits physicists who led an international study that revealed the hidden structures of quantum entangled states. The study was published in the renowned scientific journal, Nature Communications, on Friday, 27 August 2021.
Explainer: What is gravity?
We barely think about it, but gravity defines how we interact with our world. We grow up within its constraints, and our muscles, balance system, heart and blood vessels all depend on it. Gravity literally grounds us — but what exactly is it?

University of Colorado’s New Q-SEnSE Center Producing Cutting Edge Photon Counting Quantum Devices
Researchers at CU Boulder have designed one of the most precise stopwatches yet—not for timing Olympic sprinters and swimmers but for counting single photons, or the tiny packets of energy that make up light.
Making Quantum Devices With Higher-Dimensional Topological States
Linked Weyl surfaces, a novel type of topological phase that exists in five-dimensional space, were experimentally observed for the first time by a team led by Professor Shuang ZHANG from the Department of Physics at The University of Hong Kong(HKU). The work provides a unique platform for exploring various topological phases, the transition between them, and the corresponding boundary effects in five dimensions. The research paper was recently published in the renowned journal Science.
Quantum Tug-of-War and Water’s Weirdness
An international team of researchers has used a high-speed electron camera to observe the atomic motion of liquid water for the first time.
The Economist S&T: Physics Seeks the Future
Whatever the causes of these two results, they do show that there is something out there which established explanations cannot account for. Similarly unexplained anomalies were starting points for both quantum theory and relativity. It looks possible, therefore, that what has seemed one of physics’s darkest periods is about to brighten into a new morning.
