A study coordinated by the University of Trento with the University of Chicago proposes a generalized approach to the interactions between electrons and light. In the future, it may contribute to the development of quantum technologies as well as to the discovery of new states of matter. The study is published in Physical Review Letters.
Nothing in science can be achieved or understood without measurement. Today, thanks to advances in quantum sensing, scientists can measure things that were once impossible to even imagine: vibrations of atoms, properties of individual photons, fluctuations associated with gravitational waves.
Scientists build a new light source for quantum communications by combining existing technologies together to create a stronger and more robust quantum signal.
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.
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?’
This experiment offers new insights into quantum mechanics, simulating how an electron might spontaneously move backward in time.
Dynamic nuclear polarization (DNP) has revolutionized the field of nanoscale nuclear magnetic resonance (NMR), making it possible to study a wider range of materials, biomolecules and complex dynamic processes such as how proteins fold and change shape inside a cell.
A team of researchers at the University of Waterloo are combining pulsed DNP with nanoscale magnetic resonance force microscopy (MRFM) measurements to demonstrate that this process can be implemented on the nanoscale with high efficiency. The effort is overseen by Dr. Raffi Budakian, faculty member of the Institute for Quantum Computing and a professor in the Department of Physics and Astronomy, and his team consisting of Sahand Tabatabaei, Pritam Priyadarshi, Namanish Singh, Pardis Sahafi, and Dr. Daniel Tay.
The research has been published in Science Advances (“Large-Enhancement Nanoscale Dynamic Nuclear Polarization Near a Silicon Nanowire Surface”).
Measurement in quantum mechanics presents unique challenges. Observing one particle in an entangled pair determines the states of both, leading to critical inquiries: What constitutes a ‘measurement,’ and how does it influence our understanding of reality?
The complex mathematics underpinning quantum mechanics — incorporating concepts like Hilbert spaces, wave functions, and operators — can be intimidating, rendering entanglement less accessible to many.
Simply put, quantum entanglement is just too complicated for most people to fully understand. It defies classical intuitions, involves sophisticated mathematics, and urges us to reevaluate our understanding of reality.
