Published Qubits on strong stimulants



In the global push for practical quantum networks and quantum computers, an international team of researchers has demonstrated a leap in preserving the quantum coherence of quantum dot spin qubits.
Published Looking back at the Tonga eruption


A 'back-projection' technique reveals new details of the volcanic eruption in Tonga that literally shook the world.
Published Quantum physicists make major nanoscopic advance



In a new breakthrough, researchers have solved a problem that has caused quantum researchers headaches for years. The researchers can now control two quantum light sources rather than one. Trivial as it may seem to those uninitiated in quantum, this colossal breakthrough allows researchers to create a phenomenon known as quantum mechanical entanglement. This in turn, opens new doors for companies and others to exploit the technology commercially.
Published Scientists observe 'quasiparticles' in classical systems


Quasiparticles -- long-lived particle-like excitations -- are a cornerstone of quantum physics, with famous examples such as Cooper pairs in superconductivity and, recently, Dirac quasiparticles in graphene. Now, researchers have discovered quasiparticles in a classical system at room temperature: a two-dimensional crystal of particles driven by viscous flow in a microfluidic channel. Coupled by hydrodynamic forces, the particles form stable pairs -- a first example of classical quasiparticles, revealing deep links between quantum and classical dissipative systems.
Published No 'second law of entanglement' after all


When two microscopic systems are entangled, their properties are linked to each other irrespective of the physical distance between the two. Manipulating this uniquely quantum phenomenon is what allows for quantum cryptography, communication, and computation. While parallels have been drawn between quantum entanglement and the classical physics of heat, new research demonstrates the limits of this comparison. Entanglement is even richer than we have given it credit for.
Published Shedding light on quantum photonics


As buzz grows ever louder over the future of quantum, researchers everywhere are working overtime to discover how best to unlock the promise of super-positioned, entangled, tunneling or otherwise ready-for-primetime quantum particles, the ability of which to occur in two states at once could vastly expand power and efficiency in many applications.
Published Researchers uncover secrets on how Alaska's Denali Fault formed


New findings begin to fill major gaps in understanding about how geological faults behave and appear as they deepen, and they could eventually help lead future researchers to develop better earthquake models on strike-slip faults, regions with frequent and major earthquakes.
Published Can you trust your quantum simulator?


Physicists have developed a protocol to verify the accuracy of quantum experiments.
Published Blast chiller for the quantum world


The quantum nature of objects visible to the naked eye is currently a much-discussed research question. A team has now demonstrated a new method in the laboratory that could make the quantum properties of macroscopic objects more accessible than before. With the method, the researchers were able to increase the efficiency of an established cooling method by an order of a magnitude.
Published The optical fiber that keeps data safe even after being twisted or bent


An optical fiber that uses the mathematical concept of topology to remain robust, thereby guaranteeing the high-speed transfer of information, has been created by physicists.
Published The thermodynamics of quantum computing


In research on quantum computers, one aspect that has been mostly neglected until now is the generation of heat. Physicists now focus their attention on heat as an interference factor -- and have developed a method to experimentally measure the heat generated by a superconducting quantum system.
Published New quantum computing architecture could be used to connect large-scale devices


Researchers have demonstrated an architecture that can enable high fidelity and scalable communication between superconducting quantum processors. Their technique can generate and route photons, which carry quantum information, in a user-specified direction. This method could be used to develop a large-scale network of quantum processors that could efficiently communicate with one another.
Published The adverse health effects of disaster-related trauma


A new study has found that individuals from disadvantaged backgrounds are more likely to experience disaster-related home loss, and they are also more likely to develop functional limitations following the disaster.
Published Researchers show a new way to induce useful defects using invisible material properties



Much of modern electronic and computing technology is based on one idea: add chemical impurities, or defects, to semiconductors to change their ability to conduct electricity. These altered materials are then combined in different ways to produce the devices that form the basis for digital computing, transistors, and diodes. Indeed, some quantum information technologies are based on a similar principle: adding defects and specific atoms within materials can produce qubits, the fundamental information storage units of quantum computing.
Published Hawai'i earthquake swarm caused by magma moving through 'sills'


A machine-learning algorithm reveals the shape of massive subterranean structures linking active volcanoes.
Published Study shows how machine learning could predict rare disastrous events, like earthquakes or pandemics


Researchers suggest how scientists can circumvent the need for massive data sets to forecast extreme events with the combination of an advanced machine learning system and sequential sampling techniques.
Published Detrimental secondary health effects after disasters and pandemics


A study has shown that the prevalence of non-communicable diseases, which included hypertension, hyperlipidemia, diabetes, and mental disorders, increased after the Fukushima disaster and the COVID-19 outbreak. These findings emphasize the importance of improving post-disaster health promotion strategies and recommendations.
Published Chaos gives the quantum world a temperature


Two seemingly different areas of physics are related in subtle ways: Quantum theory and thermodynamics. How can the laws of thermodynamics arise from the laws of quantum physics? This question has now been pursued with computer simulations, which showed that chaos plays a crucial role: Only where chaos prevails do the well-known rules of thermodynamics follow from quantum physics.
Published Quantum dots at room temp, using lab-designed protein



Quantum dots are normally made in industrial settings with high temperatures and toxic, expensive solvents -- a process that is neither economical nor environmentally friendly. But researchers have now pulled off the process at the bench using water as a solvent, making a stable end-product at room temperature. Their work opens the door to making nanomaterials in a more sustainable way by demonstrating that protein sequences not derived from nature can be used to synthesize functional materials.
Published A peculiar protected structure links Viking knots with quantum vortices



Mathematical analysis identifies a vortex structure that is impervious to decay.
