After decades of uncertainty, a motley team of programmers has proved precisely how complicated simple computer programs can get.
Why it matters: Moore’s Law might not be dead after all. A new technique using nanomaterials can further miniaturize transistors, allowing fab plants to pack more of them on each chip. This research opens up new possibilities for creating advanced semiconductor devices with features smaller than current lithography techniques allow.
A South Korean research team led by Director Jo Moon-Ho of the Center for Van der Waals Quantum Solids within South Korea’s Institute for Basic Science has made a significant advancement in semiconductor and nanomaterial technology that could lead to the development of much smaller, more efficient, and more powerful electronic devices. The new technique can grow “one-dimentional” metallic nanaomaterials with widths as narrow as 0.4 nanometers for use as gate electrodes on 2D substrates. The technique promises to overcome the limitations of traditional lithography.
Integrated devices based on two-dimensional semiconductors exhibit excellent electrical properties even when thinned to atomic-scale thickness, making them promising candidates for creating ultra-thin, high-performance electronic devices. A separate study indicates that these 2D logic circuits are promising candidates for the post-Moore’s Law era.
The ionization energy is the amount of energy required to remove a single electron from an atom. If the atom has more than one electron, each one requires more energy than the previous one. The result is a series of increasing energy levels, and in the quantum world these energies correspond to frequencies, as in a musical scale.
This raises an interesting question: if we could hear these frequencies how would they sound? I created an app to find out, and in this video I used my app to share what I learned. As it turns out, the results are quite musical.

A new computational technique developed enables the use of surface mapping technologies like GPS to analyze subsurface geological structures.
This method, termed deformation imaging, offers insights into the rigidity of the Earth’s crust and mantle, enhancing our understanding of geological processes like earthquakes. The technique has already provided a detailed view of subsurface areas during the 2011 Tohoku earthquake and has the potential for widespread future applications with satellite data.

Researchers have developed a genetic algorithm for designing phononic crystal nanostructures, significantly advancing quantum computing and communications.
The new method, validated through experiments, allows precise control of acoustic wave propagation, promising improvements in devices like smartphones and quantum computers.
Quantum Computing Revolution
PRESS RELEASE — To perform quantum computations, quantum bits (qubits) must be cooled down to temperatures in the millikelvin range (close to-273 Celsius), to slow down atomic motion and minimize noise. However, the electronics used to manage these quantum circuits generate heat, which is difficult to remove at such low temperatures. Most current technologies must therefore separate quantum circuits from their electronic components, causing noise and inefficiencies that hinder the realization of larger quantum systems beyond the lab.
Researchers in EPFL’s Laboratory of Nanoscale Electronics and Structures (LANES), led by Andras Kis, in the School of Engineering have now fabricated a device that not only operates at extremely low temperatures, but does so with efficiency comparable to current technologies at room temperature.
AR/VR/MR glasses released in April 2024? i didnt know they were so far along already. Im curious if anyone used these, and impressions of? Still a little bulky, but, my current prediction is this will take over place of cell phones 2029/2030. But, needs to be slimmed down a bit yet; 5 years.

Researchers achieved high-vacuum levitation of a silica nanoparticle on a photonic-electric chip, revolutionizing nanotechnology.
Meta, which owns Facebook and WhatsApp, announced plans for a sprawling $800 million data center in the rural US county.
Scientists have made a significant breakthrough in creating a new method for transmitting quantum information using particles of light called qudits. These qudits promise a future quantum internet that is both secure and powerful. The study is published in the journal eLight.
Traditionally, quantum information is encoded on qubits, which can exist in a state of 0, 1, or both at the same time (superposition). This quality makes them ideal for complex calculations but limits the amount of data they can carry in communication. Conversely, qudits can encode information in higher dimensions, transmitting more data in a single go.
The new technique harnesses two properties of light—spatial mode and polarization—to create four-dimensional qudits. These qudits are built on a special chip that allows for precise manipulation. This manipulation translates to faster data transfer rates and increased resistance to errors compared to conventional methods.
