Heavier hydrogen makes silicon T centers shine brighter for quantum networks

Quantum technologies, computers or other devices that operate leveraging quantum mechanical effects, rely on the precise control of light and matter. Over the past decades, quantum physicists and material scientists have been trying to identify systems that can reliably generate photons (i.e., light particles) and could thus be used to create quantum technologies.

One approach for generating photons relies on silicon color centers, such as the emerging T center. Color centers are defects or irregularities in the crystal structure of silicon characterized by a different arrangement of atoms.

The T center and other silicon color centers can emit light in the wavelength band that is already used by fiber-optic internet cables, which is desirable for the development of quantum networks and quantum communication systems.

Scientists unveil universal aging mechanism in glassy materials

“Glass” has a unique and distinct meaning in physics—one that refers not just to the transparent material we associate with window glass. Instead, it refers to any system that looks solid but is not in true equilibrium and continues to change extremely slowly over time. Examples include window glass, plastics, metallic glasses, spin glasses (i.e., magnetic systems), and even some biological and computational systems.

When a liquid is cooled very quickly—a process called quenching—it doesn’t have time to organize into a crystal but becomes stuck in a disordered state far from equilibrium. Its properties—like stiffness and structure—slowly evolve through a process called “aging.”

Now, a research team from the Institute of Theoretical Physics of the Chinese Academy of Sciences has proposed a new theoretical framework for understanding the universal aging behavior of glassy materials. The study is published in the journal Science Advances.

Florida woman imprisoned for massive Microsoft license fraud scheme

A Florida woman was sentenced to 22 months in prison for running a massive years-long scheme to traffic thousands of stolen Microsoft Certificate of Authenticity (COA) labels.

52-year-old Heidi Richards (also known as Heidi Hastings, Heidi Shaffer, and Heidi Williams), who operated an e-commerce business called Trinity Software Distribution, was also ordered to pay a $50,000 fine.

COA labels are small stickers that authenticate software and carry unique product key codes used to activate products distributed on physical media, such as Microsoft’s Windows operating system and Office productivity suite.

These biological computers actually use neurons

In this video we look into one of the developing areas of computing: wetware. Most specifically neuromorphic computing, a science which uses actual neurons on chips.

We talk to Cortical labs, the company that developed the pong-playing dish brain, and professor Thomas Hartung to understand what the benefits of this technology are.

Replacing Silicon With Shape Shifting Molecules

As computing systems push beyond silicon limits, researchers seek materials that can do more than simply store and process data. Molecular electronics once promised ultra compact devices, but real world molecular behaviour proved unpredictable. In parallel, neuromorphic computing has aimed to build hardware that can learn and adapt like the brain. Yet most existing platforms rely on rigid materials that only imitate learning through complex circuitry.

Transient Pauli Blocking for Broadband Ultrafast Optical Switching

Researchers demonstrate this novel mechanism in degenerate InN thin films, advancing photonic technology.

The transient Pauli blocking effect is a promising way to achieve ultrafast optical switching in semiconductors. Recently, a research team from Japan successfully demonstrated broadband ultrafast optical switching in InN thin films by leveraging pump-probe transient transmittance measurements with multicolor probe lasers. They also developed a theoretical model to explain the underlying mechanism. These findings might pave the way for next-generation ultrafast optical modulators, shutters, and photonic devices in optical computing or optical communication.

Reconfigurable single-walled carbon nanotube ferroelectric field-effect transistors

Rhee et al. report scalable reconfigurable carbon nanotube transistors with a ferroelectric aluminum scandium nitride gate dielectric. They show balanced ambipolar currents, strong memory retention, and enable ternary content-addressable memory with fewer devices than traditional silicon circuits.

Physicist: I Believe You Can Enhance Your Consciousness—And Expand Your Perception Into a “Different Realm”

But what if our biological makeup limits how creative we can be? Maybe the timing of the clock that governs our introspections forces our intuitive periods—or the times of uncertainty—to be too brief. Could we use our quantum technologies to extend the wavelike processing inside our brains? I am here inspired by Aldous Huxley, who suggested in his famous book, The Doors of Perception, that drugs could alter our consciousness, revealing true reality. But rather than using drugs, I envision quantum chips designed to suppress the “noise” that induces introspection, allowing a longer interference period for our intuitive thoughts to develop. This has the potential to be far more potent than what Huxley could ever have imagined.

For my idea to work, we would first have to understand where and how these superpositions are stored and manipulated in the brain. The British physicist Roger Penrose, PhD, has speculated that this occurs within microtubules, which are dynamic, hollow, rod-like components of the eukaryotic cytoskeleton that are responsible for things such as intercellular transport. Despite some circumstantial evidence, we do not have a strong reason to believe that microtubules are capable of quantum interference, but they are certainly worth further investigation. Once we understand how our brain uses quantum effects, we could then design a quantum chip that interfaces with the relevant biological components. Theoretically, the device would be able to upload superposition states to store them for longer periods and shield them from collapse, helping us to enhance our creative wavelike thinking.

One wonders what kind of power would be unleashed by doing this. I imagine the change would not be purely quantitative, so that we merely become faster calculators or quicker problem solvers, although even that would be amazing. Instead, I think the change could be qualitative, expanding our perception into a completely different realm, effectively creating a new species. We might theoretically become more powerful than modern humans, just as we currently are with respect to other apes. Quantum-enhanced humans would see further domains of reality that would otherwise remain hidden forever from us ordinary humans.

Identifying Key Regulators in Odorant Receptor Trafficking

JNeurosci: Lu and Matsunami analyzed gene activity to find proteins that help odor-detecting receptors reach the cell surface. They identified three helper genes—Gfy, Clgn, and Syt1—that support receptor function as olfactory cells mature.

Odor detection in mammals is primarily mediated by odorant receptors (ORs), the largest family of G-protein-coupled receptors, expressed in olfactory sensory neurons (OSNs; [Buck and Axel, 1991][1]). However, most ORs exhibit little or no cell surface expression in nonolfactory cell types ([Lu et al., 2003][2]; [Hague et al., 2004][3]). While the accessory protein RTP1 and RTP2 enhance the expression of certain ORs, we hypothesized that additional proteins coregulated with RTP1 and RTP2 during OSN maturation may further enhance OR cell surface expression ([Saito et al., 2004][4]; [Zhuang and Matsunami, 2007][5]). To test this, we developed a computational pipeline based on publicly available single-cell transcriptomic data to create an interactive tool for exploring gene expression during OSN maturation.
