Kagome Metals Unlocked: A New Dimension of Superconductivity

Posted by in categories: materials, quantum physics

Kagome metals exhibit superconductivity through a unique wave-like distribution of electron pairs, a discovery that overturns previous assumptions and may lead to the development of novel superconducting components.

This groundbreaking research, driven by theoretical insights and enhanced by cutting-edge experimental techniques, marks a significant step towards realizing efficient quantum devices.

For about fifteen years, Kagome materials with their star-shaped structure reminiscent of a Japanese basketry pattern have captivated global research. Only staring from 2018 scientists have been able to synthesize metallic compounds featuring this structure in the lab. Thanks to their unique crystal geometry, Kagome metals combine distinctive electronic, magnetic, and superconducting properties, making them promising for future quantum technologies.

Quantum Magic: How Scientists Are Untangling the Universe’s Weirdest Mystery

Posted by in categories: futurism, quantum physics

Carl Kocher demystifies quantum entanglement through experimental evidence, challenging classical physics and enriching our understanding of quantum paradoxes.

Quantum entanglement may be hard to get your head around, but it’s believed to be the key to future technological applications in quantum information. In this guest editorial, inspired by his new article in Frontiers in Quantum Science and Technology, Prof Carl Kocher explains his groundbreaking 1964–67 experiments in quantum entanglement and helps us stretch our minds to understand this apparently paradoxical phenomenon.

My new article, ‘Quantum Entanglement of Optical Photons: The First Experiment, 1964−67’, is intended to convey the spirit of a small research project that reaches into uncharted territory. The article breaks with tradition, as it offers a first-person account of the strategy and challenges for the experiment, as well as an interpretation of the final result and its significance. In this guest editorial, I will introduce the subject and also attempt to illuminate the question ‘What is a paradox?’
