Interactions predicted by beyond-standard-model theories could be detected using a variation on Mössbauer spectroscopy, according to a new proposal.

Ultrabright Photons for Single-Chip Quantum Devices December 22, 2020• QuEST Lab/Stevens Institute of Technology QuEST Lab/Stevens Institute of Technology × For quantum technologies that encode and transmit information using pairs of photons, brighter is better. But integrating a suitably bright source of quantum photons into a solid-state chip remains a challenge. The best material platforms for doing that don’t live up to their theoretical potential, hindered by imperfections that...

Hair Styling with Physics Physics 13, s161 Experiments show that hair-like bundles form different shapes depending on the speed at which they are dried. J. Ha and Y. S. Kim/University of Illinois at Urbana–Champaign. J. Ha and Y. S. Kim/University of Illinois at Urbana–Champaign. × Sameh Tawfick and his teammates came across a strange occurrence a few years ago while studying how carbon nanotubes self-assemble in liquid: the tubes formed different structures depending on how fast they drie...

Emitting Radio Waves with Polarization Currents December 15, 2020• Physics 13, s160 An unconventional antenna technology can focus the radio waves emitted from the acceleration of polarization currents, aiding use of the waves in communication applications. J. Singleton J. Singleton × In conventional radio technology, radio waves are generated by accelerating charged particles, such as electrons. Now, John Singleton of Los Alamos National Laboratory, New Mexico, and colleagues have ...

Gaining a Quantum Advantage Sooner than Expected December 10, 2020• Physics 13, s159 For an important quantum many-body problem, a hybrid quantum-classical algorithm could outperform purely classical approaches using surprisingly few quantum resources.   C. Cade C. Cade × “Quantum supremacy” is reached when a quantum computer solves a problem that’s intractable for even the fastest classical computer. Claims that this has been demonstrated provoke heated debate, but even doub...

A 2D Metal Compound Shows a Superconducting Surprise December 10, 2020• Physics 13, s152 A cesium-rich “kagome” metal is both a topological insulator and a superconductor, making it a compelling material for future quantum technologies. B. Ortiz × For quantum computing applications, a topological superconductor is the stuff of dreams. Such a material could protect qubits from the environment, leading to an extremely long coherence time. Researchers think that a new class of mater...
