The Fermi Paradox: Digital Empires & Miniaturization

Posted by in categories: computing, existential risks, food

Many believe the future of humanity is to go Digital, uploading our minds to computers, living in virtual worlds that are vastly more efficient and compact. If we might do this, might distant alien empires too? And if so, might this be the reason we don’t see them?

Curiosity-Driven Exploration Makes Things More Memorable

Posted by in categories: computing, entertainment

September is the start to a new academic year. For many students, this means a fresh start and perhaps a chance to acquire some new study habits. Maybe this is the year you will stop putting everything off until the night before the exam? Now, there is some new evidence to explain why last-minute high-pressure cramming might not be the best way to retain information in the long term.

Imagine you’re an art thief planning an art heist. That was the role people played in a computer game under guidance of researchers from Duke University. But what they remembered about it one day later depended on the instructions they got when they started the game.

In this study, published in Proceedings of the… More.

A new LED design for next-level realism in immersive displays

Posted by in categories: augmented reality, computing, virtual reality

From pterodactyls flying overhead in a game to virtually applying cosmetics prior to making a purchase, augmented reality and other immersive technologies are transforming how we play, observe, and learn. Cheap and ultra-small light-emitting diodes (LEDs) that enable full-color imaging at high resolution would help immersive displays reach their full potential, but are not currently available.

Now, in a study recently published in Applied Physics Express, a team led by researchers at Meijo University and King Abdullah University of Science and Technology (KAUST) has successfully developed such LEDs. The simplicity of their fabrication, via presently available manufacturing methods, means they could be readily incorporated into modern metaverse applications.

Why is the development of improved LEDs necessary for immersive reality? The realism of augmented and depends in part on resolution, detail, and color breadth. For example, all colors must be evident and distinguishable from one another. Gallium indium nitride semiconductors are versatile materials for LEDs that meet all of these requirements.

Brain functions best in a balanced state, new study claims

Posted by in categories: biotech/medical, computing, neuroscience

A new study explores the field of biological brain modeling, determining the brain’s structure is similar to a computer.

The brain has been designated as one of the most complex organs of the human body, comprised of features including intelligence, an interpreter of the senses, an initiator of body movement, and a controller of behavior, according to the National Institute of Health.

Now, a recent study discovered that a living model of this three-pound organ sheds light on the mechanisms of how humans understand and experience the world.

Finite-depth scaling of infinite quantum circuits for quantum critical points

Posted by in categories: computing, quantum physics

Year 2022 Infinite quantum computer :3.


The scaling of the entanglement entropy at a quantum critical point allows us to extract universal properties of the state, e.g., the central charge of a conformal field theory. With the rapid improvement of noisy intermediate-scale quantum (NISQ) devices, these quantum computers present themselves as a powerful tool to study critical many-body systems. We use finite-depth quantum circuits suitable for NISQ devices as a variational ansatz to represent ground states of critical, infinite systems. We find universal finite-depth scaling relations for these circuits and verify them numerically at two different critical points, i.e., the critical Ising model with an additional symmetry-preserving term and the critical XXZ model.

Researchers develop a protocol to extend the life of quantum coherence

Posted by in categories: bioengineering, computing, quantum physics

For years, researchers have tried various ways to coax quantum bits—or qubits, the basic building blocks of quantum computers—to remain in their quantum state for ever-longer times, a key step in creating devices like quantum sensors, gyroscopes, and memories.

A team of physicists from MIT have taken an important step forward in that quest, and to do it, they borrowed a concept from an unlikely source—noise-cancelling headphones.

Led by Ju Li, the Battelle Energy Alliance Professor in Nuclear Engineering and professor of materials science and engineering, and Paola Cappellaro, the Ford Professor of Engineering in the Department of Nuclear Science and Engineering and Research Laboratory of Electronics, and a professor of physics, the team described a method to achieve a 20-fold increase in the coherence times for nuclear-spin qubits.

“Reality” is constructed by your brain. Here’s what that means, and why it matters

Posted by in categories: computing, cosmology, neuroscience, space travel

Year 2020 The ecology of the human brain is so complex that it even seems like it’s own not only story within itself but also could be like a self perpetuating universe of all sorts. Even neurons resemble the universe. What I believe is that the human brain is actually like an infinite spaceship that has infinite potential not only as a computational source but as sentience that is actual sentient in itself not just a story but kinda the god in the machine like a black box of limitless potential not only a computer but much more possibly a universe that guides us and shapes us. Even when we see the ecology of the mind we see so many stories and realities able to create its own multiverse… More.

Why a blockbuster superconductivity claim met a wall of scepticism

Posted by in categories: computing, quantum physics

Dias didn’t disappoint. He and his colleagues had created a material — lutetium mixed with nitrogen and hydrogen, or LuNH — that was a superconductor at room temperature, he announced.

That claim, which the scientists published in Nature the next day1, would have been historic — if true. Superconductors conduct electricity with zero resistance, meaning that no energy is lost as heat. But they usually work only at very low temperatures, well below −100 °C, so need expensive refrigeration. This limits their use to niche applications, such as magnetic resonance imaging scans and quantum computing. A superconducting material that needs no cooling could potentially transform electricity generation and transmission, transportation and a slew of other applications.

Dias’s claim was remarkable not only for the material’s balmy operating temperature of 21 °C (294 K), but also because it required comparatively modest pressures. Other teams working with hydrogen compounds, called hydrides, have observed superconductivity at high temperatures, but had to squeeze their samples to hundreds of gigapascals (GPa) — millions of times more than atmospheric pressure. Dias, by contrast, said that his hydride needed just 1 GPa (10,000 times atmospheric pressure): still impractical for real-world applications, but a striking advance. A patent application for LuNH, released in April, goes further, claiming superconductivity at room temperature and pressure.
