Published Controlling signal routing in quantum information processing
(via sciencedaily.com) Original source Routing signals and isolating them against noise and back-reflections are essential in many practical situations in classical communication as well as in quantum processing. In a theory-experimental collaboration, a team has achieved unidirectional transport of signals in pairs of 'one-way streets'. This research opens up new possibilities for more flexible signaling devices.
Published Physicists work to prevent information loss in quantum computing
(via sciencedaily.com) Original source Nothing exists in a vacuum, but physicists often wish this weren't the case. If the systems that scientists study could be completely isolated from the outside world, things would be a lot easier. Take quantum computing. It's a field that's already drawing billions of dollars in support from tech investors and industry heavyweights including IBM, Google and Microsoft. But if the tiniest vibrations creep in from the outside world, they can cause a quantum system to lose information.
Published Fossils reveal how ancient birds molted their feathers -- which could help explain why ancestors of modern birds survived when all the other dinosaurs died
(via sciencedaily.com) Original source Birds are the only group of dinosaurs that survived the asteroid-induced mass extinction 66 million years ago. But not all the birds alive at the time made it. Why the ancestors of modern birds lived while so many of their relatives died has been a mystery that paleontologists have been trying to solve for decades. Two new studies point to one possible factor: the differences between how modern birds and their ancient cousins molt their feathers.
Published Finding the flux of quantum technology
(via sciencedaily.com) Original source We interact with bits and bytes everyday -- whether that's through sending a text message or receiving an email. There's also quantum bits, or qubits, that have critical differences from common bits and bytes. These photons -- particles of light -- can carry quantum information and offer exceptional capabilities that can't be achieved any other way. Unlike binary computing, where bits can only represent a 0 or 1, qubit behavior exists in the realm of quantum mechanics. Through "superpositioning," a qubit can represent a 0, a 1, or any proportion between. This vastly increases a quantum computer's processing speed compared to today's computers. Experts are now investigating the inside of a quantum-dot-based light emitter.
Published An easier way to learn quantum processes
(via sciencedaily.com) Original source Scientists show that even a few simple examples are enough for a quantum machine-learning model, the 'quantum neural networks', to learn and predict the behavior of quantum systems, bringing us closer to a new era of quantum computing.
Published Scientists edge toward scalable quantum simulations on a photonic chip
(via sciencedaily.com) Original source A system using photonics-based synthetic dimensions could be used to help explain complex natural phenomena.
Published Research breakthrough could be significant for quantum computing future
(via sciencedaily.com) Original source Scientists using one of the world's most powerful quantum microscopes have made a discovery that could have significant consequences for the future of computing. Researchers have discovered a spatially modulating superconducting state in a new and unusual superconductor Uranium Ditelluride (UTe2). This new superconductor may provide a solution to one of quantum computing's greatest challenges.
Published Newly discovered Jurassic fossils in Texas
(via sciencedaily.com) Original source Scientists have filled a major gap in the state's fossil record -- describing the first known Jurassic vertebrate fossils in Texas. The weathered bone fragments are from the limbs and backbone of a plesiosaur, an extinct marine reptile.
Published Researchers make a quantum computing leap with a magnetic twist
(via sciencedaily.com) Original source Scientists and engineers have announced a significant advancement in developing fault-tolerant qubits for quantum computing. In a pair of articles, they report that, in experiments with flakes of semiconductor materials -- each only a single layer of atoms thick -- they detected signatures of 'fractional quantum anomalous Hall' (FQAH) states. The team's discoveries mark a first and promising step in constructing a type of fault-tolerant qubit because FQAH states can host anyons -- strange 'quasiparticles' that have only a fraction of an electron's charge. Some types of anyons can be used to make what are called 'topologically protected' qubits, which are stable against any small, local disturbances.
Published Humans' ancestors survived the asteroid impact that killed the dinosaurs
(via sciencedaily.com) Original source A Cretaceous origin for placental mammals, the group that includes humans, dogs and bats, has been revealed by in-depth analysis of the fossil record, showing they co-existed with dinosaurs for a short time before the dinosaurs went extinct.
Published 'Toggle switch' can help quantum computers cut through the noise
(via sciencedaily.com) Original source What good is a powerful computer if you can't read its output? Or readily reprogram it to do different jobs? People who design quantum computers face these challenges, and a new device may make them easier to solve.
Published Open-source software to speed up quantum research
(via sciencedaily.com) Original source Quantum technology is expected to fundamentally change many key areas of society. Researchers are convinced that there are many more useful quantum properties and applications to explore than those we know today. A team of researchers has now developed open-source, freely available software that will pave the way for new discoveries in the field and accelerate quantum research significantly.
Published New dinosaur discovered: Ankylosaurs may have been far more diverse than originally thought
(via sciencedaily.com) Original source First armoured dinosaur to be described from the Isle of Wight in 142 years, shows Ankylosaurs may have been far more diverse than originally thought
Published New technique in error-prone quantum computing makes classical computers sweat
(via sciencedaily.com) Original source Today's quantum computers often calculate the wrong answer because of noisy environments that interfere with the quantum entanglement of qubits. IBM Quantum has pioneered a technique that accounts for the noise to achieve reliable results. They tested this error mitigation strategy against supercomputer simulations run by physicists, and for the hardest calculations, the quantum computer bested the supercomputer. This is evidence for the utility of today's noisy quantum computers for performing real-world calculations.
Published First side-necked turtle ever discovered in UK
(via sciencedaily.com) Original source The first side-necked turtle ever to be found in the UK has been discovered by an amateur fossil collector and palaeontologists.
Published Ancient herbivore's diet weakened teeth leading to eventual starvation, study suggests
(via sciencedaily.com) Original source Researchers have shed light on the life of the ancient reptile Rhynchosaur, which walked the earth between 250-225 million years ago, before being replaced by the dinosaurs.
Published Schrödinger's cat makes better qubits
(via sciencedaily.com) Original source Drawing from Schrodinger's cat thought experiment, scientists have built a 'critical cat code' qubit that uses bosons to store and process information in a way that is more reliable and resistant to errors than previous qubit designs.
Published New dino, 'Iani,' was face of a changing planet
(via sciencedaily.com) Original source A newly discovered plant-eating dinosaur may have been a species' 'last gasp' during a period when Earth's warming climate forced massive changes to global dinosaur populations.
