A Quantum Dot (QD) is a nanometer-sized semiconductor nanocrystal that has unique optical properties such as the ability to emit light in the range of optical frequencies depending on its size. QDs have already been […]

The field of experimental quantum communication promises ways of efficient and unconditional secure information exchange in quantum states. The possibility of transferring quantum information forms a cornerstone of the emerging field of quantum communication and […]
Most scientists would blanch at being labeled a spin doctor. But when it comes to Evgeny Tsymbal, Ding-Fu Shao and their colleagues, the lab coat fits. Click to rate this post! [Total: 0 Average: 0]You […]
While working with helium nanodroplets, scientists at the Department of Ion Physics and Applied Physics led by Fabio Zappa and Paul Scheier have come across a surprising phenomenon: When the ultracold droplets hit a hard […]
In a study published in Physical Review-Physics Education Research, a research team led by Academician Guo Guangcan from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences has successfully […]
The change between singlet and triplet states of electron pairs in charge-separated states plays an important role in nature. Presumably, the compass of migratory birds can also be explained by the influence of the earth’s […]
Created as an analogy for Quantum Electrodynamics (QED) — which describes the interactions due to the electromagnetic force carried by photons — Quantum Chromodynamics (QCD) is the theory of physics that explains the interactions mediated by the strong force — one […]
A large, unconventional anomalous Hall resistance in a new magnetic semiconductor in the absence of large-scale magnetic ordering has been demonstrated by Tokyo Tech materials scientists, validating a recent theoretical prediction. Their findings provide new […]
Which factors determine how fast a quantum computer can perform its calculations? Physicists at the University of Bonn and the Technion—Israel Institute of Technology have devised an elegant experiment to answer this question. The results […]
While conventional electronics relies on the transport of electrons, components that convey spin information alone may be many times more energy efficient. Physicists at the Technical University of Munich (TUM) and the Max Planck Institute […]
