Published Umbrella for atoms: The first protective layer for 2D quantum materials
(via sciencedaily.com) Original source As silicon-based computer chips approach their physical limitations in the quest for faster and smaller designs, the search for alternative materials that remain functional at atomic scales is one of science's biggest challenges. In a groundbreaking development, researchers have engineered a protective film that shields quantum semiconductor layers just one atom thick from environmental influences without compromising their revolutionary quantum properties. This puts the application of these delicate atomic layers in ultrathin electronic components within realistic reach.
Published Resurrecting niobium for quantum science
(via sciencedaily.com) Original source Niobium has long been considered an underperformer in superconducting qubits. Scientists have now engineered a high-quality niobium-based qubit, taking advantage of niobium's superior qualities.
Published Scientists closer to solving mysteries of universe after measuring gravity in quantum world
(via sciencedaily.com) Original source Scientists are closer to unravelling the mysterious forces of the universe after working out how to measure gravity on a microscopic level. Experts have never fully understood how the force works in the tiny quantum world -- but now physicists have successfully detected a weak gravitational pull on a tiny particle using a new technique.
Published Measuring the properties of light: Scientists realize new method for determining quantum states
(via sciencedaily.com) Original source Scientists have used a new method to determine the characteristics of optical, i.e. light-based, quantum states. For the first time, they are using certain photon detectors -- devices that can detect individual light particles -- for so-called homodyne detection. The ability to characterize optical quantum states makes the method an essential tool for quantum information processing.
Published Biggest Holocene volcano eruption found by seabed survey
(via sciencedaily.com) Original source A detailed survey of the volcanic underwater deposits around the Kikai caldera in Japan clarified the deposition mechanisms as well as the event's magnitude. As a result, the research team found that the event 7,300 years ago was the largest volcanic eruption in the Holocene by far.
Published New detection method aims to warn of landslide tsunamis
(via sciencedaily.com) Original source Researchers have devised a way to remotely detect large landslides within minutes of occurrence and to quickly determine whether they are close to open water and present a tsunami hazard.
Published Electrons become fractions of themselves in graphene
(via sciencedaily.com) Original source Physicists have observed fractional quantum Hall effect in simple pentalayer graphene. The finding could make it easier to develop more robust quantum computers.
Published Engineers achieve breakthrough in quantum sensing
(via sciencedaily.com) Original source A collaborative project has made a breakthrough in enhancing the speed and resolution of wide-field quantum sensing, leading to new opportunities in scientific research and practical applications.
Published Earthquake fatality measure offers new way to estimate impact on countries
(via sciencedaily.com) Original source A new measure that compares earthquake-related fatalities to a country's population size concludes that Ecuador, Lebanon, Haiti, Turkmenistan, Iran and Portugal have experienced the greatest impact from fatalities in the past five centuries.
Published A new design for quantum computers
(via sciencedaily.com) Original source Creating a quantum computer powerful enough to tackle problems we cannot solve with current computers remains a big challenge for quantum physicists. A well-functioning quantum simulator -- a specific type of quantum computer -- could lead to new discoveries about how the world works at the smallest scales. Quantum scientists have developed a guide on how to upgrade these machines so that they can simulate even more complex quantum systems.
Published 1,000 atomic qubits and rising
(via sciencedaily.com) Original source Making quantum systems more scalable is one of the key requirements for the further development of quantum computers because the advantages they offer become increasingly evident as the systems are scaled up. Researchers have recently taken a decisive step towards achieving this goal.
Published Early-stage subduction invasion
(via sciencedaily.com) Original source Our planet's lithosphere is broken into several tectonic plates. Their configuration is ever-shifting, as supercontinents are assembled and broken up, and oceans form, grow, and then start to close in what is known as the Wilson cycle.
Published Fundamental equation for superconducting quantum bits revised
(via sciencedaily.com) Original source Physicists have uncovered that Josephson tunnel junctions -- the fundamental building blocks of superconducting quantum computers -- are more complex than previously thought. Just like overtones in a musical instrument, harmonics are superimposed on the fundamental mode. As a consequence, corrections may lead to quantum bits that are 2 to 7 times more stable. The researchers support their findings with experimental evidence from multiple laboratories across the globe.
Published A 'quantum leap' at room temperature
(via sciencedaily.com) Original source Scientists have achieved a milestone by controlling quantum phenomena at room temperature.
Published Researchers show classical computers can keep up with, and surpass, their quantum counterparts
(via sciencedaily.com) Original source A team of scientists has devised means for classical computing to mimic a quantum computing with far fewer resources than previously thought. The scientists' results show that classical computing can be reconfigured to perform faster and more accurate calculations than state-of-the-art quantum computers.
Published Technique could improve the sensitivity of quantum sensing devices
(via sciencedaily.com) Original source A new technique can control a larger number of microscopic defects in a diamond. These defects can be used as qubits for quantum sensing applications, and being able to control a greater number of qubits would improve the sensitivity of such devices.
Published Combining materials may support unique superconductivity for quantum computing
(via sciencedaily.com) Original source A new fusion of materials, each with special electrical properties, has all the components required for a unique type of superconductivity that could provide the basis for more robust quantum computing.
Published Ancient rocks improve understanding of tectonic activity between earthquakes
(via sciencedaily.com) Original source Rocks once buried deep in ancient subduction zones -- where tectonic plates collide -- could help scientists make better predictions of how these zones behave during the years between major earthquakes, according to a research team.
Published New method to more accurately spot underground nuclear tests
(via sciencedaily.com) Original source A more accurate way of identifying underground nuclear tests, including those conducted in secret, has been developed.
Published A new origin story for deadly Seattle fault
(via sciencedaily.com) Original source The Seattle fault zone is a network of shallow faults slicing through the lowlands of Puget Sound, threatening to create damaging earthquakes for the more than four million people who live there. A new origin story, proposed in a new study, could explain the fault system's earliest history and help scientists improve hazard modeling for the densely populated region.
