Researchers have developed a breakthrough method for quantum information transmission using light particles called qudits, which utilize the spatial mode and polarization properties to enable faster, more secure data transfer and increased resistance to errors.

This technology could greatly enhance the capabilities of a quantum internet, providing long-distance, secure communication, and leading to the development of powerful quantum computers and unbreakable encryption.

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.

New research introduces a non-thermal method for magnetization using circularly polarized XUV light, which induces significant magnetization changes through the inverse Faraday effect, potentially transforming ultrafast data storage and spintronics.

Intense laser pulses can be used to manipulate or even switch the magnetization orientation of a material on extremely short time scales. Typically, such effects are thermally induced, as the absorbed laser energy heats up the material very rapidly, causing an ultrafast perturbation of the magnetic order.

Scientists from the Max Born Institute (MBI), in collaboration with an international team of researchers, have now demonstrated an effective non-thermal approach of generating large magnetization changes. By exposing a ferrimagnetic iron-gadolinium alloy to circularly polarized pulses of extreme ultraviolet (XUV) radiation, they could reveal a particularly strong magnetic response depending on the handedness of the incoming XUV light burst (left-or right-circular polarization).

The first Samsung 60TB SSD, the BM1743, has been launched. The company believes it is possible to launch a 120TB SSD in the future.

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.

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.

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.
