A compound of cerium, ruthenium, and tin — with surprising properties. Credit: TU Wien A research team from TU Wien together with US research institutes came across a surprising form of ‘quantum criticality’; this could lead to a design concept for new materials. In everyday life, phase transitions usually have […]

False-colour scanning electron micrograph of device A (upper panel) and its schematics (lower panel). Side gates and contacts are Cr/Au (10 nm/100 nm). The Al shell thickness is approximately 10 nm. The substrate is p-doped Si, acting as a global back-gate, covered by 285 nm SiO2. The two tunnel-gates are shorted externally, as are […]

Artistic impression of different spacecraft designs considering theoretical shapes of different kinds of “warp bubbles.” Credit: E Lentz Astrophysicist at Göttingen University discovers new theoretical hyper-fast soliton solutions. If travel to distant stars within an individual’s lifetime is going to be possible, a means of faster-than-light propulsion will have to […]

ANIMATION Study by the University of Bonn determines minimum time for complex quantum operations. Even in the world of the smallest particles with their own special rules, things cannot proceed infinitely fast. Physicists at the University of Bonn have now shown what the speed limit is for complex quantum operations. […]

A quantum circuit. Credit: Aalto University Simulation of non-Hermitian quantum mechanics using a quantum computer goes beyond centuries-old conventions. Aalto researchers have used an IBM quantum computer to explore an overlooked area of physics, and have challenged 100-year-old cherished notions about information at the quantum level. The rules of quantum […]

In a study published in Physical Review Letters, the team led by academician GUO Guangcan from University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) made progress in high dimensional quantum teleportation. The researchers demonstrated the teleportation of high-dimensional states in a three-dimensional six-photon system. […]

Researchers at JQI have discovered a quantum system that is a hybrid of order and chaos.   ANIMATION Normally the word “chaos” evokes a lack of order: a hectic day, a teenager’s bedroom, tax season. And the physical understanding of chaos is not far off. It’s something that is extremely difficult […]
