An innovative method now allows DNA to store information as a binary code — the same strings of 0s and 1s used by standard computers.
‘Bricks’ of DNA, some of which have chemical tags, could one day be an alternative to storing information electronically.
A team of researchers has for the first time successfully used lasers to generate guided sound waves on the surface of a microchip. These acoustic waves, akin to the surface waves produced during an earthquake, travel across the chip at frequencies nearly a billion times higher than those found in earth tremors.
By containing the sound wave on the surface of a chip, it can more easily interact with the environment, making it a perfect candidate for advanced sensing technologies.
The findings are published in APL Photonics.
For the first time since the discovery of the material MnBi2Te4 (MBT), researchers at the University of Twente have successfully made it behave like a superconductor. This marks an important step in understanding MBT and is significant for future technologies, such as new methods of information processing and quantum computing.
MBT is a recently discovered material attracting attention due to its unique magnetic and topological properties. In their research, the scientists examined how electricity behaves in the material. The findings are published in the journal Communications Materials.
MBT’s topological properties cause electrons to move only along the edges of the material, and in theory, they should only move in a clockwise direction. However, the experiments at Twente demonstrated that under certain conditions, the electrons can rotate both clockwise and counterclockwise.
These scientists aren’t focused on the existence of quantum entanglement, but are keen on uncovering how it begins — how exactly do two particles become quantum entangled?
Using advanced computer simulations, they’ve managed to peek into processes that happen on attosecond timescales — a billionth of a billionth of a second.
Quantum entanglement is a strange and fascinating phenomenon where two particles become so interconnected that they share a single state.
Researchers at MIT have unexpectedly stumbled upon a way to 3D print active electronics – meaning transistors and components for controlling electrical signals – without the use of semiconductors or even special fabrication technology.
That goes far beyond what we can currently do with 3D printers. And if perfected, this method could eventually spell the beginning of a new wave in prototyping, experimentation, and even DIY projects for tinkerers at home.
With 3D printing, any of a range of materials including thermoplastic filaments, resin, ceramic, and metal, are laid down in successive thin layers to form a three-dimensional object. That means you can print all kinds of things, from action figures to jewelry to furniture to buildings.
For the first time, an international cadre of electrical engineers has developed a new method for photonic in-memory computing that could make optical computing a reality in the near future.
The smallest machine of its kind in the world uses a single photon as its qubit and it can perform calculations without needing the cumbersome equipment to cool it down to near absolute zero.
Pioneers of quantum computing have shared their dreams and skepticism about the fledgling industry, while Gov. JB Pritzker said he thinks it’s already attracting companies to Illinois.
A difficult-to-describe nanoscale object called the magnetic skyrmion might one day yield new microelectronic devices that can do much more—for example, massive data storage—all while consuming much less power.
