Quantum computer unveils atomic dynamics of light-sensitive molecules      (via sciencedaily.com) 

Researchers have implemented a quantum-based method to observe a quantum effect in the way light-absorbing molecules interact with incoming photons. Known as a conical intersection, the effect puts limitations on the paths molecules can take to change between different configurations. The observation method makes use of a quantum simulator, developed from research in quantum computing, and offers an example of how advances in quantum computing are being used to investigate fundamental science.

Do measurements produce the reality they show us?      (via sciencedaily.com) 

The measurement values determined in sufficiently precise measurements of physical systems will vary based on the relation between the past and the future of a system determined by its interactions with the meter. This finding may explain why quantum experiments often produce paradoxical results that can contradict our common-sense idea of physical reality.

Demon hunting: Physicists confirm 67-year-old prediction of massless, neutral composite particle      (via sciencedaily.com) 

In 1956, theoretical physicist David Pines predicted that electrons in a solid can do something strange. While they normally have a mass and an electric charge, Pines asserted that they can combine to form a composite particle that is massless, neutral, and does not interact with light. He called this particle a 'demon.' Now, researchers have finally found Pines' demon 67 years after it was predicted.

Potential application of unwanted electronic noise in semiconductors      (via sciencedaily.com) 

Random telegraph noise (RTN) in semiconductors is typically caused by two-state defects. Two-dimensional (2D) van der Waals (vdW) layered magnetic materials are expected to exhibit large fluctuations due to long-range Coulomb interaction; importantly, which could be controlled by a voltage compared to 3D counterparts having large charge screening. Researchers reported electrically tunable magnetic fluctuations and RTN signal in multilayered vanadium-doped tungsten diselenide (WSe2) by using vertical magnetic tunneling junction devices. They identified bistable magnetic states in the 1/f2 RTNs in noise spectroscopy, which can be further utilized for switching devices via voltage polarity.
