Quantum leap: Photon discovery is a major step toward at-scale quantum technologies

A team of physicists has developed the first integrated photon source with the potential to deliver large-scale quantum photonics. The development of quantum technologies promises to have a profound impact across science, engineering and society. Quantum computers at scale will be able to solve problems intractable on even the most powerful current supercomputers, with many revolutionary applications, for example, in the design of new drugs and materials.

4-D electric circuit network with topology

In recent years, topology has emerged as an important tool to classify and characterize properties of materials. It has been found that many materials exhibit a number of unusual topological properties, which are unaffected by deformations, e.g., stretching, compressing, or twisting. These topological properties include quantized Hall currents, large magnetoresistance, and surface excitations that are immune to disorder.

Counting kinks in a collapsing ring to predict stability

A team of researchers from the University of Oxford, MIT and the University of Limerick has found that it is possible to predict the stability of a collapsing ring by counting its kinks. In their paper published in the journal Physical Review Letters, the group describes experiments they conducted that involved placing an elastic ring over a soap film and recording what happens when the ring collapses.

Scientists use light to accelerate supercurrents, access forbidden light, quantum world

Scientists are using light waves to accelerate supercurrents to access the unique and potentially useful properties of the quantum world.

How Many Galaxies Are There? Astronomers Are Revealing the Enormity of the Universe

The universe is awash in islands of matter — some 100 billion galaxies make up the basic building blocks of the cosmos.

Detecting individual nuclear spins with single rare-earth ions hosted in crystals

Rare-earth minerals are a class of materials with similar properties that are currently used to build a variety of devices, including LEDs, rechargeable batteries, magnets, lasers, and much more. These materials' electron spins can be hosted in crystals, creating systems with unique characteristics that could serve as interfaces between telecom-band photons and long-lived spin quantum bits.

A vacuum ultraviolet photoionization time-of-flight mass spectrometer to analyze gas-phase radical reaction

The research group led by Prof. Zhang Weijun at Anhui Institute of Optics and Fine Mechanics under Hefei Institutes of Physical Science has made new progress on the vacuum ultraviolet (VUV) photoionization mass spectrometry for gas-phase radical reactions.

Image analysis technique provides better understanding of heart cell defects

Heart disease is the leading cause of death in the United States and other industrialized nations, and many patients face limited treatment options. Fortunately, stem cell biology has enabled researchers to produce large numbers of cardiomyocytes, the cells that make up the heart or cardiac muscle and have the potential to be used in advanced drug screens and cell-based therapies.

Team in Germany observes Pauli crystals for the first time

A team of researchers at Heidelberg University has succeeded in building an apparatus that allowed them to observe Pauli crystals for the first time. They have written a paper describing their efforts and have uploaded it to the arXiv preprint server.

Longstanding mystery of matter and antimatter may be solved

An element which could hold the key to the long-standing mystery around why there is much more matter than antimatter in our Universe has been discovered by a University of the West of Scotland (UWS)-led team of physicists.
