Forgetting feels like a failure of attention, but physics treats it as a fundamental process with a measurable price. At the smallest scales, erasing information is not free, it consumes energy and ...

The 2025 Nobel prize in physics has been awarded to John Clarke, Michel Devoret and John Martinis for their work on showing how quantum particles can mysteriously tunnel through matter, a process that ...

ETH Zurich scientists have levitated a tower of three nano glass spheres using optical tweezers, suppressing almost all classical motion to observe quantum zero-point fluctuations with unprecedented ...

It is something like the "Holy Grail" of physics: unifying particle physics and gravitation. The world of tiny particles is described extremely well by quantum theory, while the world of gravitation ...

In many quantum materials—materials with unusual electrical and magnetic properties driven by quantum mechanical effects—electrons can organize themselves into Landau levels. Landau levels are ...

Quantum mechanics is one of the most successful theories in science — and makes much of modern life possible. Technologies ranging from computer chips to medical-imaging machines rely on the ...

With a clever design, researchers have solved eddy-current damping in macroscopic levitating systems, paving the way for a wide range of sensing technologies Levitation has long been pursued by stage ...

One of this year’s winners of the Nobel Prize in Physics warned that China is rapidly narrowing the gap with the US in quantum computing. “China is definitely very competitive in this,” John Martinis ...

My doctoral research focuses on analyzing how the disorder affects the transport of different kinds of quantum materials, e.g., topological insulator thin films and nanowires, quantum Hall GaAs/AlGaAs ...
