Published Researcher uses artificial intelligence to discover new materials for advanced computing



Researchers have identified novel van der Waals (vdW) magnets using cutting-edge tools in artificial intelligence (AI). In particular, the team identified transition metal halide vdW materials with large magnetic moments that are predicted to be chemically stable using semi-supervised learning. These two-dimensional (2D) vdW magnets have potential applications in data storage, spintronics, and even quantum computing.
Published Physicists discover 'stacked pancakes of liquid magnetism'



Physicists have discovered stacked pancakes of 'liquid' magnetism that may account for the strange electronic behavior of some layered helical magnets.
Published A cocktail party of 3D-printed robot heads



Imagine a cocktail party full of 3D-printed, humanoid robots listening and talking to each other. That seemingly sci-fi scene is the goal of an augmented listening laboratory. With precise control over the simulated subjects, the researchers can adjust the parameters of the experiment and even set the machines in motion to simulate neck movements.
Published Leaky-wave metasurfaces: A perfect interface between free-space and integrated optical systems



Researchers have developed a new class of integrated photonic devices -- 'leaky-wave metasurfaces' -- that convert light initially confined in an optical waveguide to an arbitrary optical pattern in free space. These are the first to demonstrate simultaneous control of all four optical degrees of freedom. Because they're so thin, transparent, and compatible with photonic integrated circuits, they can be used to improve optical displays, LIDAR, optical communications, and quantum optics.
Published Symmetric graphene quantum dots for future qubits



Quantum dots in semiconductors such as silicon or gallium arsenide have long been considered hot candidates for hosting quantum bits in future quantum processors. Scientists have now shown that bilayer graphene has even more to offer here than other materials. The double quantum dots they have created are characterized by a nearly perfect electron-hole-symmetry that allows a robust read-out mechanism -- one of the necessary criteria for quantum computing.
Published Scurrying centipedes inspire many-legged robots that can traverse difficult landscapes



Intrigued to see if the many limbs could be helpful for locomotion in this world, a team of physicists, engineers, and mathematicians are using this style of movement to their advantage. They developed a new theory of multilegged locomotion and created many-legged robotic models, discovering the robot with redundant legs could move across uneven surfaces without any additional sensing or control technology as the theory predicted.
Published Quantum lidar prototype acquires real-time 3D images while fully submerged underwater



Researchers have demonstrated a prototype lidar system that uses quantum detection technology to acquire 3D images while submerged underwater. The high sensitivity of this system could allow it to capture detailed information even in extremely low-light conditions found underwater.
Published Researchers develop manual for engineering spin dynamics in nanomagnets



An international team of researchers has developed a comprehensive manual for engineering spin dynamics in nanomagnets -- an important step toward advancing spintronic and quantum-information technologies.
Published The future of data storage lies in DNA microcapsules



Storing data in DNA sounds like science fiction, yet it lies in the near future. Experts expect the first DNA data center to be up and running within five to ten years. Data won't be stored as zeros and ones in a hard drive but in the base pairs that make up DNA: AT and CG. Such a data center would take the form of a lab, many times smaller than the ones today.
Published QuanÂtum comÂputer in reverse gear



Large numbers can only be factorized with a great deal of computational effort. Physicists are now providing a blueprint for a new type of quantum computer to solve the factorization problem, which is a cornerstone of modern cryptography.
Published A touch-responsive fabric armband -- for flexible keyboards, wearable sketchpads



It's time to roll up your sleeves for the next advance in wearable technology -- a fabric armband that's actually a touch pad. Researchers say they have devised a way to make playing video games, sketching cartoons and signing documents easier. Their proof-of-concept silk armband turns a person's forearm into a keyboard or sketchpad. The three-layer, touch-responsive material interprets what a user draws or types and converts it into images on a computer.
Published Self-folding origami machines powered by chemical reaction



Scientists have harnessed chemical reactions to make microscale origami machines self-fold -- freeing them from the liquids in which they usually function, so they can operate in dry environments and at room temperature.
Published Quantum entanglement of photons doubles microscope resolution



Using a "spooky" phenomenon of quantum physics, researchers have discovered a way to double the resolution of light microscopes.
Published Sensor enables high-fidelity input from everyday objects, human body



Couches, tables, sleeves and more can turn into a high-fidelity input device for computers using a new sensing system.
Published Speedy robo-gripper reflexively organizes cluttered spaces



A new gripper robot grasps by reflex. Rather than start from scratch after a failed attempt, the bot adapts in the moment to reflexively roll, palm, or pinch an object to get a better hold.
Published Tunneling electrons



By superimposing two laser fields of different strengths and frequency, the electron emission of metals can be measured and controlled precisely to a few attoseconds. Physicists have shown that this is the case. The findings could lead to new quantum-mechanical insights and enable electronic circuits that are a million times faster than today.
Published How a horse whisperer can help engineers build better robots



New research shows us that age-old interactions between people and their horses can teach us something about building robots designed to improve our lives.
Published Jellyfish-like robots could one day clean up the world's oceans



Roboticists have developed a jellyfish-inspired underwater robot with which they hope one day to collect waste from the bottom of the ocean. The almost noise-free prototype can trap objects underneath its body without physical contact, thereby enabling safe interactions in delicate environments such as coral reefs. Jellyfish-Bot could become an important tool for environmental remediation.
Published Scientists demonstrate unprecedented sensitivity in measuring time delay between two photons



A team of researchers has demonstrated the ultimate sensitivity allowed by quantum physics in measuring the time delay between two photons. This breakthrough has significant implications for a range of applications, including more feasible imaging of nanostructures, including biological samples, and nanomaterial surfaces, as well as quantum enhanced estimation based on frequency-resolved boson sampling in optical networks.
