Who Knows What Consciousness Is?

Posted by in categories: biotech/medical, neuroscience, quantum physics

At the risk of sounding a bit woo-woo, as any speculation about the “hard problem” of the unknowns of consciousness does, can’t both be true? In other words, is it possible that Schrödinger’s “total mind” is a kind of quantum reserve downloaded and differentially phased into qualia through the materialist medium of natural selection, which Edelman calls “neural Darwinism”? Is it the embodied human sensory organs interacting with their environment in feedback loops that unveils the unformed wave of fundamental consciousness through the particle of particular experience?

The correct answer is: Who knows?

“Who Knows?” would be an apt title for the best inventory to date of the myriad views on consciousness, from the metaphysical to the materialist, compiled by Robert Lawrence Kuhn and titled “A landscape of consciousness: toward a taxonomy of explanations and implications,” recently published in the journal “Progress in Biophysics and Molecular Biology.”

SAS Defines Hybrid Reality For Quantum Computing

Posted by in categories: computing, internet, quantum physics

Quantum is huge. Because quantum computing allows us to step beyond the current limitations of digital systems, it paves the way for a new era of computing machines with previously unthinkable power. Without recounting another simplified explanation of how quantum gets its power at length, we can reference the double-slit experiment and perhaps the spinning coin explanation.

A coin sat on a desk is either heads or tails, rather like the 1s and 0s that express the on or off values in binary code. Quantum theorists would prefer we think of the coin above the desk, spinning in the air. In this state, the coin is both heads and tails at the same time. This is because, at the quantum level, both values exist until we make an observation of its state at any given point in time. We could further increase the number of positions possible (literally known as quantum superposition) by altering the angle of view we take on the coin, which is somewhat similar to how we work with qubits in quantum mechanics.

So then, Schrödinger’s cat is both alive and dead at the same time and the dummies guide to quantum entanglement is out there on the web if needed. What matters most now is how we will make practical use of quantum computing and where it will be applied for best advantage.

Physicists throw world’s smallest disco party with a levitating ball of fluorescent nanodiamond

Posted by in categories: energy, nanotechnology, quantum physics

“This breakthrough helps us better understand and study the fascinating world of quantum physics,” he says.

The fluorescent nanodiamonds, with an average diameter of about 750 nm, were produced through high-pressure, high-temperature synthesis. These diamonds were irradiated with high-energy electrons to create nitrogen-vacancy color centers, which host electron spin qubits.

When illuminated by a green laser, they emitted red light, which was used to read out their electron spin states. An additional infrared laser was shone at the levitated nanodiamond to monitor its rotation. Like a disco ball, as the nanodiamond rotated, the direction of the scattered infrared light changed, carrying the rotation information of the nanodiamond.

New spin on quantum theory forces rethink of a fundamental physics law

Posted by in categories: particle physics, quantum physics

In the quantum realm, a particle’s properties can be separate from the particle itself, including its angular momentum – which could require a rethinking of fundamental laws.

NIST’s post-quantum cryptography standards are here

Posted by in categories: encryption, information science, quantum physics

The US National Institute of Standards and Technology has released Federal Information Processing Standards (FIPS) publications for three quantum-resistant cryptographic algorithms.

In a landmark announcement, the National Institute of Standards and Technology (NIST) has published its first set of post-quantum cryptography (PQC) standards. This announcement serves as an inflection point in modern cybersecurity: as the global benchmark for cryptography, the NIST standards signal to enterprises, government agencies, and supply chain vendors that the time has come to make the world’s information security systems resistant to future cryptographically relevant quantum computers.

NIST Finalizes Post-Quantum Encryption Standards

Posted by in categories: cybercrime/malcode, encryption, information science, quantum physics

Three new encryption algorithms to bolster global cybersecurity efforts against future attacks using quantum technologies were published today by the National Institute of Standards and Technology (NIST), a division of the U.S. Department of Commerce. The new standards are designed for two tasks: general encryption and digital signatures.

These new standards are the culmination of an eight-year effort from the agency to tap the best minds in cybersecurity to devise the next generation of cryptography strong enough to withstand quantum computers. Experts expect quantum computers capable of breaking current current cryptographic algorithms within a decade. The new standards, the first released by NIST’s post-quantum cryptography (PQC) standardization project, are published on the department’s website. The documents contain the algorithms’ computer code, instructions for how to implement them in products and in encryption systems, and use cases for each.
