Semiconducting perovskites that exhibit superfluorescence at room temperature do so due to built-in thermal "shock absorbers" which protect dipoles within the material from thermal interference.
The maximum speed of signal transmission in microchips is about one petaherz (one million gigahertz), which is about 100,000 times faster than current transistors.
How fast can electronics be? When computer chips work with ever shorter signals and time intervals, at some point they come up against physical limits.
In recent years, artificial intelligence has become ubiquitous, with applications such as speech interpretation, image recognition, medical diagnosis, and many more. At the same time, quantum technology has been proven capable of computational power well beyond the reach of even the world's largest supercomputer.
Researchers have developed a new high-purity single-photon source that can operate at room temperature. The source is an important step toward practical applications of quantum technology, such as highly secure communication based on quantum key distribution (QKD).
To accurately diagnose and treat diseases, doctors and researchers need to see inside bodies. Medical imaging tools have come a long way since the humble x-ray, but most existing tools remain too coarse to quantify numbers or specific types of cells inside deep tissues of the body.
Scientists from the Faculty of Pure and Applied Sciences at the University of Tsukuba have developed a method for monitoring the temperature using the naturally occurring atom-like defects in diamonds.
Computers, smartphones, GPS: quantum physics has enabled many technological advances. It is now opening up new fields of research in cryptography (the art of coding messages) with the aim of developing ultra-secure telecommunications networks.
Superconductivity is a macroscopic quantum state characterized by the disappearance of electrical resistance in materials at extremely low temperatures.
Galaxies rarely live alone. Instead, dozens to thousands are drawn together by gravity, forming vast clusters that are the largest objects in the universe.
