Published Major milestone achieved in new quantum computing architecture



Researchers report a significant advance in quantum computing. They have prolonged the coherence time of their single-electron qubit to an impressive 0.1 milliseconds, nearly a thousand-fold improvement.
Published New quantum effect demonstrated for the first time: Spinaron, a rugby in a ball pit



Experimental physicists have demonstrated a new quantum effect aptly named the 'spinaron.' In a meticulously controlled environment and using an advanced set of instruments, they managed to prove the unusual state a cobalt atom assumes on a copper surface. This revelation challenges the long-held Kondo effect -- a theoretical concept developed in the 1960s, and which has been considered the standard model for the interaction of magnetic materials with metals since the 1980s.
Published Uranus aurora discovery offers clues to habitable icy worlds



Astronomers confirm the existence of an infrared (IR) aurora on Uranus. This could help astronomers identify exoplanets that might support life, a large number of which are icy worlds.
Published Using sound to test devices, control qubits



Researchers have developed a system that uses atomic vacancies in silicon carbide to measure the stability and quality of acoustic resonators. What's more, these vacancies could also be used for acoustically-controlled quantum information processing, providing a new way to manipulate quantum states embedded in this commonly-used material.
Published Massive space explosion observed creating elements needed for life



Scientists have observed the creation of rare chemical elements in the second-brightest gamma-ray burst ever seen -- casting new light on how heavy elements are made.
Published Scientists discover molten layer covering Martian core



NASA's InSight mission to Mars helped scientists map out Mars' internal structure, including the size and composition of its core, and provided general hints about its tumultuous formation. But findings from a new paper could lead to reanalysis of that data. An international team of researchers discovered the presence of a molten silicate layer overlying Mars' metallic core -- providing new insights into how Mars formed, evolved and became the barren planet it is today.
Published Astrophysicists scan the Galaxy for signs of life



Astrophysicists are scanning the Universe for 'technosignatures' emanating from distant planets that would provide support for the existence of intelligent, alien life. Researchers plan to monitor millions of star systems.
Published Researchers probe how a piece of the moon became a near-Earth asteroid



Two years after the striking discovery that a near-Earth asteroid could be a chunk of the moon, another UArizona research group has found that a rare pathway could have enabled this to happen.
Published LIGO surpasses the quantum limit



Researchers report a significant advance in quantum squeezing, which allows them to measure undulations in space-time across the entire range of gravitational frequencies detected by LIGO.
Published The Moon is 40 million years older than previously thought



By analyzing tiny lunar crystals gathered by Apollo 17 astronauts in 1972, researchers recalculated the age of the Earth's Moon. Although previous assessments estimated the Moon as 4.425 billion years old, the new study discovered it is actually 4.46 billion years old -- 40 million years older than previously thought.
Published Astronomers detect most distant fast radio burst to date



An international team has spotted a remote blast of cosmic radio waves lasting less than a millisecond. This 'fast radio burst' (FRB) is the most distant ever detected. Its source was pinned down by the European Southern Observatory's (ESO) Very Large Telescope (VLT) in a galaxy so far away that its light took eight billion years to reach us. The FRB is also one of the most energetic ever observed; in a tiny fraction of a second it released the equivalent of our Sun's total emission over 30 years.
Published Electrical control of quantum phenomenon could improve future electronic devices



A new electrical method to conveniently change the direction of electron flow in some quantum materials could have implications for the development of next-generation electronic devices and quantum computers. A team of researchers has developed and demonstrated the method in materials that exhibit the quantum anomalous Hall (QAH) effect -- a phenomenon in which the flow of electrons along the edge of a material does not lose energy.
Published Self-correcting quantum computers within reach?



Quantum computers promise to reach speeds and efficiencies impossible for even the fastest supercomputers of today. Yet the technology hasn't seen much scale-up and commercialization largely due to its inability to self-correct. Quantum computers, unlike classical ones, cannot correct errors by copying encoded data over and over. Scientists had to find another way. Now, a new paper illustrates a quantum computing platform's potential to solve the longstanding problem known as quantum error correction.
Published Exploring parameter shift for quantum fisher information



Scientists have developed a technique called 'Time-dependent Stochastic Parameter Shift' in the realm of quantum computing and quantum machine learning. This breakthrough method revolutionizes the estimation of gradients or derivatives of functions, a crucial step in many computational tasks.
Published A new way to erase quantum computer errors



Researchers have demonstrated a type of quantum eraser. The physicists show that they can pinpoint and correct for mistakes in quantum computing systems known as 'erasure' errors.
Published 'Starquakes' could explain mystery signals



Fast radio bursts, or FRBs, are an astronomical mystery, with their exact cause and origins still unconfirmed. These intense bursts of radio energy are invisible to the human eye, but show up brightly on radio telescopes. Previous studies have noted broad similarities between the energy distribution of repeat FRBs, and that of earthquakes and solar flares. However, new research has looked at the time and energy of FRBs and found distinct differences between FRBs and solar flares, but several notable similarities between FRBs and earthquakes. This supports the theory that FRBs are caused by 'starquakes' on the surface of neutron stars. This discovery could help us better understand earthquakes, the behavior of high-density matter and aspects of nuclear physics.
Published Twisted science: New quantum ruler to explore exotic matter



Researchers have developed a 'quantum ruler' to measure and explore the strange properties of multilayered sheets of graphene, a form of carbon. The work may also lead to a new, miniaturized standard for electrical resistance that could calibrate electronic devices directly on the factory floor, eliminating the need to send them to an off-site standards laboratory.
Published Scientists discover the highest energy gamma-rays ever from a pulsar



Scientists have detected the highest energy gamma rays ever from a dead star called a pulsar. The energy of these gamma rays clocked in at 20 tera-electronvolts, or about ten trillion times the energy of visible light. This observation is hard to reconcile with the theory of the production of such pulsed gamma rays, as the international team reports.
Published Plot thickens in hunt for ninth planet



A pair of theoretical physicists are reporting that the same observations inspiring the hunt for a ninth planet might instead be evidence within the solar system of a modified law of gravity originally developed to understand the rotation of galaxies.
Published Machine learning used to probe the building blocks of shapes



Applying machine learning to find the properties of atomic pieces of geometry shows how AI has the power to accelerate discoveries in maths.
