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 AI-generated academic science writing can be identified with over 99% accuracy
(via sciencedaily.com) Original source The debut of artificial intelligence chatbot ChatGPT has set the world abuzz with its ability to churn out human-like text and conversations. Still, many telltale signs can help us distinguish AI chatbots from humans, according to a new study. Based on the signs, the researchers developed a tool to identify AI-generated academic science writing with over 99% accuracy.
Published New superconducting diode could improve performance of quantum computers and artificial intelligence
(via sciencedaily.com) Original source A team has developed a more energy-efficient, tunable superconducting diode -- a promising component for future electronic devices -- that could help scale up quantum computers for industry and improve artificial intelligence systems.
Published Wireless olfactory feedback system to let users smell in the VR world
(via sciencedaily.com) Original source A research team recently invented a novel, wireless, skin-interfaced olfactory feedback system that can release various odours with miniaturized odor generators (OGs). The new technology integrates odors into virtual reality (VR)/augmented reality (AR) to provide a more immersive experience, with broad applications ranging from 4D movie watching and medical treatment to online teaching.
Published The digital dark matter clouding AI
(via sciencedaily.com) Original source Scientists using artificial intelligence technology may be inviting unwanted noise into their genome analyses. Now, researchers have created a computational correction that will allow them to see through the fog and find genuine DNA features that could signal breakthroughs in health and medicine.
Published Shining a light on neuromorphic computing
(via sciencedaily.com) Original source AI, machine learning, and ChatGPT may be relatively new buzzwords in the public domain, but developing a computer that functions like the human brain and nervous system -- both hardware and software combined -- has been a decades-long challenge. Engineers are exploring how optical "memristors" may be a key to developing neuromorphic computing.
Published Quantum computers are better at guessing, new study demonstrates
(via sciencedaily.com) Original source Researchers have demonstrated a quantum speedup over the most efficient classical computer algorithm possible for what is believed to be the first time. The accomplishment was performed on an IBM Montreal Quantum Falcon r4 27-qubit device.
Published New method improves efficiency of 'vision transformer' AI systems
(via sciencedaily.com) Original source Vision transformers (ViTs) are powerful artificial intelligence (AI) technologies that can identify or categorize objects in images -- however, there are significant challenges related to both computing power requirements and decision-making transparency. Researchers have now developed a new methodology that addresses both challenges, while also improving the ViT's ability to identify, classify and segment objects in images.
Published The 'breath' between atoms -- a new building block for quantum technology
(via sciencedaily.com) Original source Researchers have discovered they can detect atomic 'breathing,' or the mechanical vibration between two layers of atoms, by observing the type of light those atoms emitted when stimulated by a laser. The sound of this atomic 'breath' could help researchers encode and transmit quantum information.
Published Newborn baby inspires sensor design that simulates human touch
(via sciencedaily.com) Original source As we move into a world where human-machine interactions are becoming more prominent, pressure sensors that are able to analyze and simulate human touch are likely to grow in demand.
Published Self-driving cars lack social intelligence in traffic
(via sciencedaily.com) Original source Self-driving cars fall short when it comes to understanding the social codes in traffic that let human drivers decide whether to give way or drive on, according to new research.
Published New tool may help spot 'invisible' brain damage in college athletes
(via sciencedaily.com) Original source An artificial intelligence computer program that processes magnetic resonance imaging (MRI) can accurately identify changes in brain structure that result from repeated head injury, a new study in student athletes shows. These variations have not been captured by other traditional medical images such as computerized tomography (CT) scans. The new technology, researchers say, may help design new diagnostic tools to better understand subtle brain injuries that accumulate over time.
Published Source-shifting metastructures composed of only one resin for location camouflaging
(via sciencedaily.com) Original source Acoustic source-shifters make observers mis-perceive the location of sound by reproducing a sound emanating from a location different from the actual location of a sound source. Researchers have now developed a design approach to produce high-performance source-shifters using a common polymer for location camouflage. Utilizing inverse design based on topology optimization, this development could pave the way for advanced augmented reality and holography technology.
Published Robot centipedes go for a walk
(via sciencedaily.com) Original source Researchers show how their multilegged walking robot can be steered by inducing a dynamic instability. By making the couplings between segments more flexible, the robot changes from walking straight to moving in a curved path. This work can lead to more energy-efficient and reliable robotic navigation of terrain.
Published Super low-cost smartphone attachment brings blood pressure monitoring to your fingertips
(via sciencedaily.com) Original source Engineers have developed a simple 3D-printed attachment that clips over a smartphone's camera and flash to measure blood pressure at the user's fingertip. The clip works with a custom smartphone app and currently costs about 80 cents to make. Researchers say it could help make regular blood pressure monitoring easy, affordable and accessible to people in resource-poor communities.
Published Making the structure of 'fire ice' with nanoparticles
(via sciencedaily.com) Original source Cage structures made with nanoparticles could be a route toward making organized nanostructures with mixed materials, and researchers have shown how to achieve this through computer simulations.
Published Quantum scientists accurately measure power levels one trillion times lower than usual
(via sciencedaily.com) Original source Scientists have developed a nanodevice that can measure the absolute power of microwave radiation down to the femtowatt level at ultra-low temperatures -- a scale trillion times lower than routinely used in verifiable power measurements. The device has the potential to significantly advance microwave measurements in quantum technology.
