Researchers have developed a way to address many quantum dots with only a few control lines using a chessboard-like method. This enabled the operation of the largest gate-defined quantum dot system ever. Their result is an important step in the development of scalable quantum systems for practical quantum technology.

Quantum dots can be used to hold qubits, the foundational building blocks of a quantum computer. Currently, each qubit requires its own addressing line and dedicated control electronics. This is highly impractical and in stark contrast with today’s computer technology, where billions of transistors are operated with only a few thousand lines.

A new nanoscience study led by a researcher at the Department of Energy’s Oak Ridge National Laboratory takes a big-picture look at how scientists study materials at the smallest scales.

The paper, published in Science Advances, reviews leading work in subsurface nanometrology, the science of internal measurement at the nanoscale level, and suggests quantum sensing could become the foundation for the field’s next era of discoveries. Potential applications could range from mapping intracellular structures for targeted drug delivery to characterizing quantum materials and nanostructures for the advancement of quantum computing.

“Our goal was to define the state of the art and to consider what’s been done and where we need to go,” said Ali Passian, an ORNL senior research scientist and senior author of the study.

We are about to leap into the age of quantum computing and possibly our technological capabilities will evolve rapidly as a result.

Does this mean we are on the threshold of developing a Type 2 civilization?
If so, we should soon be able to make first contact with other intelligent life forms and slowly conquer space.

Going from 49kB of transient program area to 60kB took only a single NAND chip, in this interesting experiment in vintage bank-switching.

Researchers have a new way to connect quantum devices over long distances, a necessary step toward allowing the technology to play a role in future communications systems.

While today’s classical data signals can get amplified across a city or an ocean, quantum signals cannot. They must be repeated in intervals—that is, stopped, copied and passed on by specialized machines called quantum repeaters. Many experts believe these quantum repeaters will play a key role in future communication networks, allowing enhanced security and enabling connections between remote quantum computers.

A new Princeton study titled “Indistinguishable telecom band photons from a single erbium ion in the solid state” and published Aug. 30 in Nature, details the basis for a new approach to building quantum repeaters. It sends telecom-ready light emitted from a single ion implanted in a crystal. The effort was many years in the making, according to Jeff Thompson, the study’s principal author. The work combined advances in photonic design and materials science.

New research may lead to highly precise, power-efficient light measurement tools, driving advancements in various technology fields.

Researchers have discovered a way to improve optical frequency combs to measure light waves with much higher precision than previously accomplished. This could lead to the development and improvement of devices that require such precision, like atomic clocks. The researchers showed that dissipative Kerr solitons (DKSs) can create chip-based optical frequency combs with enough output power for use in optical atomic clocks and other practical applications.

Security Enhanced Linux (SELinux) has been part of the mainline kernel for two decades to provide a security module implementing access control security policies and is now widely-used for enhancing the security of production Linux servers and other systems. Those that haven’t been involved with Linux for a long time may be unaware that SELinux originates from the US National Security Agency (NSA). But now with Linux 6.6 the NSA references are being removed.

The United States National Security Agency worked on the original code around Security Enhanced Linux and was the primary original developer. The NSA has continued to contribute to SELinux over the years while with its increased adoption does see contributions from a wide range of individuals and organizations.

Michael Levin is a Distinguished Professor in the Biology department at Tufts University. He holds the Vannevar Bush endowed Chair and serves as director of the Allen Discovery Center at Tufts and the Tufts Center for Regenerative and Developmental Biology. To explore the algorithms by which the biological world implemented complex adaptive behavior, he got dual B.S. degrees, in CS and in Biology and then received a PhD from Harvard University. He did post-doctoral training at Harvard Medical School, where he began to uncover a new bioelectric language by which cells coordinate their activity during embryogenesis. The Levin Lab works at the intersection of developmental biology, artificial life, bioengineering, synthetic morphology, and cognitive science.

For millions of Chinese people, the first software they download on a new laptop or smartphone is always the same: a keyboard app. Yet few of them are aware that it may make everything they type vulnerable to spying eyes.

Since dozens of Chinese characters can share the same latinized phonetic spelling, the ordinary QWERTY keyboard alone is incredibly inefficient. A smart, localized keyboard app can save a lot of time and frustration by predicting the characters and words a user wants to type. Today, over 800 million Chinese people use third-party keyboard apps on their PCs, laptops, and mobile phones.
