How Schrödinger’s cat makes better qubits
An illustration of Schrödinger’s cat code. Credit: Vincenzo Savona (EPFL) Quantum computing uses the principles of quantum mechanics to encode and elaborate data, meaning that it could one day solve…
Calculation shows why heavy quarks get caught up in the flow
The data points on this graph show that the interactions of heavy quarks (Q) with the quark-gluon plasma (QGP) are strongest and have a short mean free path (zig zags)…
Revolutionizing optical control with topological edge states
Manipulating topological edge states for optical channel switcher. Credit: Bing-Cong Xu Nanophotonics and topology have generated significant interest due to the unique properties they offer. One area of focus is…
A simple solution for nuclear matter in two dimensions
In dense nuclear matter, quarks “line up,” becoming essentially one-dimensional. Calculations considering that single dimension plus time can track how low energy excitations ripple through nuclear matter. Credit: Brookhaven National…
An optical method to polarize free electrons in a laboratory setting
Credit: Pan and Xu Polarized electrons are electrons in which spins have a “preferred” orientation or are preferentially oriented in a specific direction. The realization of these electrons has notable…
Tiny quantum electronic vortexes can circulate in superconductors in ways not seen before
A new study by KTH Royal Institute of Technology and Stanford University revises of our understanding of quantum vortices in superconductors. Pictured, an artist’s depiction of quantum vortices. Credit: Greg…
Optical effect advances quantum computing with atomic qubits to a new dimension
The Talbot effect forms periodic patterns from laser light (simulation). Single atom qubits can be stored and processed at the high intensity points (red). Credit: TU Darmstadt/APQ Darmstadt physicists have…
The ‘breath’ between atoms—a new building block for quantum technology
Credit: Pixabay/CC0 Public Domain University of Washington researchers have discovered they can detect atomic “breathing,” or the mechanical vibration between two layers of atoms, by observing the type of light…
