Towards compact quantum computers, thanks to topology

Jan 20, 2022 (Nanowerk News) Researchers at PSI have compared the electron distribution below the oxide layer of two semiconductors. The investigation is part of an effort to develop particularly stable quantum bits –and thus, in turn, particularly efficient quantum computers. They have now published their latest research in the...

Watching the charge move in photoexcited molecules

Jan 20, 2022 (Nanowerk News) An international research team led by Markus Gühr’s group at the University of Potsdam performed laser experiments at DESY's free-electron laser FLASH to monitor charge motions in light-excited molecules of thiouracil, which is a modified nucleobase. This class of molecules has a variety of medical...

Enhancing simulations of curved space with qubits

Jan 20, 2022 (Nanowerk News) One of the mind-bending ideas that physicists and mathematicians have come up with is that space itself—not just objects in space—can be curved. When space curves (as happens dramatically near a black hole), sizes and directions defy normal intuition. Something as straightforward as defining a...

New type of supernova discovered

Jan 20, 2022 (Nanowerk News) In the not-so-distant past, the discovery of a supernova – an exploding star – was considered a rare occasion. When Prof. Avishay Gal-Yam of the Weizmann Institute’s Particle Physics and Astrophysics Department was a doctoral student, for example, he located seven of them over the...

‘Superpower’ nano bubbles could treat, prevent current and future strains of SARS-CoV-2

Jan 20, 2022 (Nanowerk News) Scientists at Northwestern Medicine and The University of Texas MD Anderson Cancer Center have identified natural nano-bubbles containing the ACE2 protein (evACE2) in the blood of COVID-19 patients and discovered these nano-sized particles can block infection from broad strains of SARS-CoV-2 virus in preclinical studies....

a new way to control the polarization of light

Jan 19, 2022 (Nanowerk News) For quantum communication or optical computing it is important to measure and to influence in which direction a light wave is oscillating. It is now for the first time possible to manipulate this polarization of a continuous laser wave with a special glass fibre, which...
