Published Computer scientists discover new vulnerability affecting computers globally
(via sciencedaily.com) A team o computer science researchers has uncovered a line of attack that breaks all Spectre defenses, meaning that billions of computers and other devices across the globe are just as vulnerable today as they were when Spectre was first announced.
Published Materials advances are key to development of quantum hardware
(via sciencedaily.com) A new article argues that the ability to move forward on developing useful quantum computers requires new major advances in materials science, engineering and fabrication. The authors call for new approaches from broad areas of science and engineering.
Published Transforming circles into squares
(via sciencedaily.com) Researchers have developed a method to change a cellular material's fundamental topology at the microscale.
Published Facial recognition ID with a twist: Smiles, winks and other facial movements for access
(via sciencedaily.com) Concurrent Two-Factor Identity Verification requires both one's facial identity and a specific facial motion to gain access. To set it up, a user faces a camera and records a short 1-2 second video of either a unique facial motion or a lip movement from reading a secret phrase. The video is then input into the device, which extracts facial features and the features of the facial motion, storing them for later ID verification.
Published Researchers discover that privacy-preserving tools leave private data anything but
(via sciencedaily.com) Researchers explored whether private data could still be recovered from images that had been 'sanitized'' by such deep-learning discriminators as privacy protecting GANs (PP-GANs).
Published Heat-free optical switch would enable optical quantum computing chips
(via sciencedaily.com) In a potential boost for quantum computing and communication, a European research collaboration reported a new method of controlling and manipulating single photons without generating heat. The solution makes it possible to integrate optical switches and single-photon detectors in a single chip.
Published Laser system generates random numbers at ultrafast speeds
(via sciencedaily.com) Scientists have developed a system that can generate random numbers over a hundred times faster than current technologies, paving the way towards faster, cheaper, and more secure data encryption in today's digitally connected world.
Published Quantum systems learn joint computing
(via sciencedaily.com) Researchers realize quantum-logic computer operation between two separate quantum modules in different laboratories.
Published Quantum computing: When ignorance is wanted
(via sciencedaily.com) Quantum technologies for computers open up new concepts of preserving the privacy of input and output data of a computation. Scientists have shown that optical quantum systems are not only particularly suitable for some quantum computations, but can also effectively encrypt the associated input and output data.
Published Cybersecurity vulnerabilities of common seismological equipment
(via sciencedaily.com) Seismic monitoring devices linked to the internet are vulnerable to cyberattacks that could disrupt data collection and processing, say researchers who have probed the devices for weak points.
Published Say goodbye to the dots and dashes to enhance optical storage media
(via sciencedaily.com) A new technology is aimed at modernizing the optical digital storage technology. This advancement allows for more data to be stored and for that data to be read at a quicker rate. Rather than using the traditional dots and dashes as commonly used in these technologies, the innovators encode information in the angular position of tiny antennas, allowing them to store more data per unit area.
Published Researchers improve data readout by using 'quantum entanglement'
(via sciencedaily.com) Researchers say they have been able to greatly improve the readout of data from digital memories - thanks to a phenomenon known as 'quantum entanglement'.
Published Physicists observe competition between magnetic orders
(via sciencedaily.com) Two-dimensional materials, consisting of a single layer of atoms, have been booming in research for years. They possess novel properties that can only be explained with the help of the laws of quantum mechanics. Researchers have now used ultracold atoms to gain new insights into previously unknown quantum phenomena. They found out that the magnetic orders between two coupled thin films of atoms compete with each other.
Published A biochemical random number
(via sciencedaily.com) Original source Scientists have generated a huge true random number using DNA synthesis. It is the first time that a number of this magnitude has been created by biochemical means.
Published Researchers simulate privacy leaks in functional genomics studies
(via sciencedaily.com) Original source Researchers demonstrate that it's possible to de-identify raw functional genomics data to ensure patient privacy. They also demonstrate how these raw data could be linked back to specific individuals through their gene variants by something as simple as an abandoned coffee cup if these sanitation measures are not put in place.
