In a new study from Skoltech and the University of Kentucky, researchers found a new connection between quantum information and quantum field theory. This work attests to the growing role of quantum information theory across various areas of physics. The paper was published in the journal Physical Review Letters.
Quantum information plays an increasingly important role as an organizing principle connecting various branches of physics. In particular, the theory of quantum error correction, which describes how to protect and recover information in quantum computers and other complex interacting systems, has become one of the building blocks of the modern understanding of quantum gravity.
“Normally, information stored in physical systems is localized. Say, a computer file occupies a particular small area of the hard drive. By “error” we mean any unforeseen or undesired interaction which scrambles information over an extended area. In our example, pieces of the computer file would be scattered over different areas of the hard drive. Error correcting codes are mathematical protocols that allow collecting these pieces together to recover the original information. They are in heavy use in data storage and communication systems. Quantum error correcting codes play a similar role in cases when the quantum nature of the physical system is important,” Anatoly Dymarsky, Associate Professor at the Skoltech Center for Energy Science and Technology (CEST), explains.
Last year, computer engineers from Northwestern University and Delft University of Technology (TU Delft) introduced the world’s first battery-free Game Boy, which harvests both solar energy and the user’s kinetic energy from button mashing to power an unlimited lifetime of game play.
The same team now introduces a new platform that enables makers, hobbyists and novice programmers to build their own battery-free electronic devices that run with intermittent, harvested energy.
Called BFree, the system includes energy-harvesting hardware (the BFree Shield) and a power-failure-resistant version of Python, one of the most accessible and most used programming languages. All the user needs is a basic understanding of Python in order to quickly and easily turn any do-it-yourself (DIY) smart device into a battery-free version. With this technology, novice programmers can now turn their DIY battery-powered motion sensor, for example, into a solar-powered sensor with an infinite lifetime.

Computer simulations hint that a Mars-sized twin of Earth could be lurking somewhere in the solar system’s mysterious ‘third zone’! Let’s find it.
Ummm wtf o.o!

The features of vibrations provide key information on the surrounding environment. Here the authors show that a common computational principle underlies vibrotactile pitch perception in both mice and humans.

Reverse-engineering our thinking should be done in terms of networks, modules, algorithms and second-order emergence — meta-algorithms, or groups of modules. Neuronal circuits correlate to “immaterial” cognitive modules, and these cognitive algorithms, when activated, produce meta-algorithmic conscious awareness and phenomenal experience, all in all at least two layers of emergence on top of “physical” neurons.
Reality is fundamentally experiential. Nothing is real for us until perceived. The Conscious Instant Hypothesis denotes that we experience waking reality as a series of perceptual frames. Phenomenal mind springs into existence at increments of conscious instants. A series of such conscious instants constitutes a data stream of consciousness. In a sense, consciousness is really mind-based computing of your experiential branch in this quantum multiverse.
John Archibald Wheeler (1911−2008) was one of the first prominent physicists to propose that reality might not be wholly physical, in some sense, our cosmos must be a “participatory” phenomenon requiring the act of conscious observation — and thus consciousness itself. Wheeler also drew attention to implicit connection between physics and information theory, which was invented in 1948 by mathematician Claude Shannon. Just as physics builds on elementary particles, the quanta, defined by measurement, so does information theory. Its “quantum” is the binary unit, or bit, which is a signal represented by one of two choices: yes or no, plus or minus, zero or one. With his famous “it from bit” concept he unites quantum information theory to consciousness and physics.
While Wheeler emphasized bits at his time, it appears that intrinsically quantum-mechanical forms of information – now known as ‘qubits’ – are even more fundamental. In recent years a rising number of theorists have been exploring whether these curious quanta of information may hold the answer to combining quantum theory and general relativity into a quantum theory of gravity.
If we are to reason for the non-dual picture of the world then quantum physics is directly linked to consciousness. The human brain is a physical organ that transmits and interprets electrochemical signals. Its biochemistry is certainly governed by quantum physical laws, and consciousness — which is clearly related to the functioning of the brain — must therefore be related to the quantum physical processes going on within the brain and in the cosmos at large.

Chipmakers are still catching up to demand following severe supply chain bottlenecks created by the pandemic. But manufacturing plants that were planned last year will likely start producing chips in the coming months, helping to alleviate shortages for PC parts and other microchips, Su said.
“We’ve always gone through cycles of ups and downs, where demand has exceeded supply, or vice versa,” Su said at the Code Conference in Beverly Hills, California. “This time, it’s different.”
The improvements will be gradual as more manufacturing capacity becomes available, Su said.
A new computer model demonstrates that vaccinations have impacts well beyond just preventing disease and death: they can also slow the spread of antimicrobial resistance.
Pneumococcal diseases—which include illnesses ranging from inner ear infections to pneumonia and meningitis—are a leading cause of death globally among children under five. While there are effective vaccines against pneumococcal diseases, access is still a challenge for populations in low-income—and some middle income—countries. And antimicrobial resistance to the antibiotics commonly used to treat these infections is a growing problem.
“We wanted to model the value of vaccinating—not only to show that vaccination reduces death or disability from these diseases, but also to quantify whether vaccination can slow antimicrobial resistance,” says Andrew Stringer, an assistant professor of veterinary and global health at NC State.
