Published Quantum computer unveils atomic dynamics of light-sensitive molecules


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.
Published Which radio waves disrupt the magnetic sense in migratory birds?


Many songbirds use the earth's magnetic field as a guide during their migrations, but radiowaves interfere with this ability. A new study has found an upper bound for the frequency that disrupts the magnetic compass.
Published Making the invisible, visible: New method makes mid-infrared light detectable at room temperature


Scientists have developed a new method for detecting mid-infrared (MIR) light at room temperature using quantum systems.
Published Scientists use quantum device to slow down simulated chemical reaction 100 billion times


Using a trapped-ion quantum computer, the research team witnessed the interference pattern of a single atom caused by a 'conical intersection'. Conical intersections are known throughout chemistry and are vital to rapid photo-chemical processes such as light harvesting in human vision or photosynthesis.
Published New quantum device generates single photons and encodes information


A new approach to quantum light emitters generates a stream of circularly polarized single photons, or particles of light, that may be useful for a range of quantum information and communication applications. A team stacked two different, atomically thin materials to realize this chiral quantum light source.
Published Breakthrough in beta-lactam synthesis using nickel catalysts


Researchers have made a significant breakthrough in the field of asymmetric synthesis of beta-lactams, which are prominent in bioactive compounds. Their innovative approach employs nickel and hydrocarbon sources that are abundant on Earth to access value-added beta-lactam products. The employment of nickel-hydride catalysis and alkenyl dioxazolone derivatives gives rise to the selective formation of four-membered lactam products.
Published Light regulates structural conversion of chiral molecules


A team of chemists have developed a novel concept in which a mixture of molecules that behave like mirror images is converted to a single form. To this end, they use light as external energy source. The conversion is relevant e.g. for the preparation of drugs.
Published Do measurements produce the reality they show us?


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.
Published Hot chemistry quickly transforms aromatic molecules into harmful aerosols


A research group has established key early steps in the conversion of aromatic molecules, a major constituent of traffic and other urban volatile emissions, into aerosol. Their findings increase understanding of the chemical processes that degrade urban air quality and influence climate change.

A team has created an artificial quantum magnet featuring a quasiparticle made of entangled electrons, the triplon.
Published Scientists develop fermionic quantum processor


Researchers have designed a new type of quantum computer that uses fermionic atoms to simulate complex physical systems. The processor uses programmable neutral atom arrays and is capable of simulating fermionic models in a hardware-efficient manner using fermionic gates. The team demonstrated how the new quantum processor can efficiently simulate fermionic models from quantum chemistry and particle physics.
Published Steam condenser coating could save 460M tons of CO2 annually


If coal and natural gas power generation were 2% more efficient, then, every year, there could be 460 million fewer tons of carbon dioxide released and 2 trillion fewer gallons of water used. A recent innovation to the steam cycle used in fossil fuel power generation could achieve this.
Published The trio -- nickel, palladium, and platinum -- for enhanced hydrogen evolution


A research team enhanced hydrogen evolution catalyst through stepwise deposition.
Published Topology's role in decoding energy of amorphous systems


Researchers used topological data analysis to improve the predictions of physical properties of amorphous materials by machine-learning algorithms. This may allow for cheaper and faster calculations of material properties.

Researchers have developed an epoxy resin that can be repaired and recycled, in addition to being flame-retardant and mechanically strong. Potential applications range from coating for wooden flooring to composites in aerospace and railways.
Published Deciphering the molecular dynamics of complex proteins


Which structures do complex proteins adopt in solution? Biophysicists answer this question using the example of ubiquitin dimers as well as a new combination of high-resolution NMR spectroscopy and sophisticated computer simulations.
Published Sharing chemical knowledge between human and machine


Researchers have developed a platform that uses artificial neural networks to translate chemical structural formulae into machine-readable form. With this platform, they have created a tool with which this information from scientific publications can be automatically fed into databases. Until now, this had to be done literally by hand and was time-consuming.
Published New approach shows hydrogen can be combined with electricity to make pharmaceutical drugs


The world needs greener ways to make chemicals. In a new study, researchers demonstrate one potential path toward this goal by adapting hydrogen fuel cell technologies.

Physicists use a 350-year-old theorem that explains the workings of pendulums and planets to reveal new properties of light waves.
Published Demon hunting: Physicists confirm 67-year-old prediction of massless, neutral composite particle


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.
