“This will change the paradigm of Moore’s Law.”

Moore’s Law predicted that the number of transistors on a microchip would double every year after 1960, though that rate would eventually hit a wall due to the fact silicone loses electrical properties past a certain size.

One possible solution comes in the form of 2D materials, also known as single-layer materials. These incredibly delicate two-dimensional sheets of perfect crystals are only a single atom thin. Crucially, at the nanometer scale, they can conduct electrons far more efficiently than silicon.

For years, encryption has played a core role in securing enterprise data. However, as quantum computers become more advanced, traditional encryption solutions and public-key cryptography (PKC) standards, which enterprise and consumer vendors rely on to secure their products, are at serious risk of decryption.

Today, IBM Institute for Business Value issued a new report titled Security in the Quantum Era, examining the reality of quantum risk and the need for enterprise adoption of quantum-safe capabilities to safeguard the integrity of critical applications and infrastructure as the risk of decryption increases.

One question for Paul Sutter, author of “The Remarkable Emptiness of Existence,” an article in Nautilus this month. Sutter is a theoretical cosmologist at the Institute for Advanced Computational Science at Stony Brook University, where he studies cosmic voids, maps the leftover light from the big bang, and develops new techniques for finding the first stars to appear in the cosmos.

What is our universe expanding into?

That’s a great question. The answer, though, is that it’s not a great question. It’s a little tricky, so let me walk you through it. Yes, our universe is expanding. Our universe has no center and no edge. The Big Bang didn’t happen in one location in space. The Big Bang happened everywhere in the cosmos simultaneously. The Big Bang was not a point in space. It was a point in time. It exists in all of our paths.

As buzz grows ever louder over the future of quantum, researchers everywhere are working overtime to discover how best to unlock the promise of super-positioned, entangled, tunneling or otherwise ready-for-primetime quantum particles, the ability of which to occur in two states at once could vastly expand power and efficiency in many applications.

Developmentally, however, quantum devices today are “about where the computer was in the 1950s,” which it is to say, the very beginning. That’s according to Kamyar Parto, a sixth-year Ph.D. student in the UC Santa Barbara lab of Galan Moody, an expert in quantum photonics and an assistant professor of electrical and computer engineering.

Parto is co-lead author of a paper published in the journal Nano Letters, describing a key advance: the development of a kind of on-chip “factory” for producing a steady, fast stream of single photons, essential to enabling photonic-based quantum technologies.

For millions of years, nature has basically been getting by with just a few elements from the periodic table. Carbon, calcium, oxygen, hydrogen, nitrogen, phosphorus, silicon, sulfur, magnesium and potassium are the building blocks of almost all life on our planet (tree trunks, leaves, hairs, teeth, etc). However, to build the world of humans—including cities, health care products, railways, airplanes and their engines, computers, smartphones, and more—many more chemical elements are needed.

A recent article, published in Trends in Ecology and Evolution and written by researchers from CREAF, the Universitat Autònoma de Barcelona (UAB) and the Spanish National Research Council (CSIC), warns that the range of chemical elements humans need (something scientifically known as the human elementome) is increasingly diverging from that which nature requires (the biological elementome).

In 1900, approximately 80% of the elements humans used came from biomass (wood, plants, food, etc.). That figure had fallen to 32% by 2005, and is expected to stand at approximately 22% in 2050. We are heading for a situation in which 80% of the elements we use are from non-biological sources.

For decades, transistors—the heart of computer chips—have been getting smaller and smaller. As a result, the electronic components in many devices can be made even more compact, faster and also more powerful. But is this development coming to a natural halt? The smaller the components, the greater the danger that individual defects in the atomic structure will significantly change the behavior of the component. This applies to the established silicon technology and novel nanotechnologies based on 2D materials.

At Vienna University of Technology (TU Wien), intensive work has been done on the physical description of this problem at the transistor level. Now the researchers are going a step further and looking at the influence of defects at the level of electronic circuits, which sometimes consist of several—sometimes even billions—of transistors. In some cases, individual transistors can operate outside the desired specification, but still perform well as part of a circuit consisting of several transistors. With this new approach at the circuit level, significant advances in miniaturization are still possible.

The study is published in the journal Advanced Materials.

If a brain is uploaded into a computer, will consciousness continue in digital form or will it end forever when the brain is destroyed? Philosophers have long debated such dilemmas and classify them as questions about personal identity. There are currently three main theories of personal identity: biological, psychological, and closest continuer theories. None of these theories can successfully address the questions posed by the possibility of uploading. I will argue that uploading requires us to adopt a new theory of identity, psychological branching identity. Psychological branching identity states that consciousness will continue as long as there is continuity in psychological structure. What differentiates this from psychological identity is that it allows identity to continue in multiple selves.
