A new material created by Oregon State University researchers is a key step toward the next generation of supercomputers.
Perhaps the strangest prediction of quantum theory is entanglement, a phenomenon whereby two distant objects become intertwined in a manner that defies both classical physics and a common-sense understanding of reality. In 1935, Albert Einstein expressed his concern over this concept, referring to it as "spooky action at a distance."
In recent years, nanofabricated mechanical oscillators have emerged as a promising platform for quantum information applications. Quantum entanglement of engineered optomechanical resonators would offer a compelling route toward scalable quantum networks. Researchers at the TU Delft and the University of Vienna have now observed this entanglement and report their findings in this week's edition of Nature.
A Northwestern University and Argonne National Laboratory research team has developed an exceptional next-generation material for nuclear radiation detection that could provide a significantly less expensive alternative to the detectors now in commercial use.
Currently, most of the magnetic sensors used in today's computers, airplanes, cars, and other systems distort the magnetic fields that they are measuring. These distortions can cause major problems for some applications, in particular biomedical techniques, that require highly accurate measurements, and can also cause cross-talk in sensor arrays.
A pair of researchers with Victoria University of Wellington has suggested that the way to prevent future blockchains from future hackers using quantum computers is to use quantum blockchains. Theoretical physicists Del Rajan and Matt Visser explain their idea in a paper they have uploaded to the arXiv preprint server.
New technique drawing on echo state networks fills in the gaps to simulate how arrhythmic electrical signals go chaotic
Cardiac arrhythmia results when the usual symphony of electric pulses that keep the heart's muscles in sync becomes chaotic. Although symptoms are often barely noticeable, arrhythmia leads to hundreds of thousands of deaths from unexpected, sudden cardiac arrest in the United States each year. A major issue that limits modeling to predict such events is that it is impossible to measure and monitor all the hundreds of variables that come together to make our hearts tick.
Although microfluidics devices have a wide variety of uses, from point-of-care diagnostics to environmental analysis, one major limitation is that they cannot be modified for different uses on the fly, since their flow paths are set during fabrication. In a new study, researchers have addressed this limitation by designing electrogates that can regulate the flow of liquid at different points along the microchannel—a process that can be entirely controlled with a smartphone.
Stitches help deep cuts heal, but can leave a scar. Now, a new study conducted by a team of researchers at the University of Toronto may help scientists and medical professionals move toward scar-free wound repair.
From energy materials to disease diagnostics, new microscopy techniques can provide more nuanced insight. Researchers first need to understand the effects of radiation on samples.
Fluid dynamics is not something that typically comes to mind when thinking about bitcoin. But for one Stanford physicist, the connection is as simple as stirring your coffee.
Yale's latest work expanding the reach of quantum information science is actually a game of quantum pitch and catch.
Cotton thread is made of many tiny fibers, each just 2-3 cm long, yet when spun together the fibers are capable of transmitting tension over indefinitely long distances. From a physics perspective, how threads and yarns transmit tension—making them strong enough to keep clothes from falling apart—is a long-standing puzzle that is not completely understood.
Scientists at U.S. Department of Energy (DOE) national laboratories are collaborating to test a magnetic property of the muon. Their experiment could point to the existence of physics beyond our current understanding, including undiscovered particles.
