Circa 2015 what if we didn’t need computers we only needed our minds upgraded? Quantum cognition talks about a theory of an upgraded mind.

What type of probability theory best describes the way humans make judgments under uncertainty and decisions under conflict? Although rational models of cognition have become prominent and have achieved much success, they adhere to the laws of classical probability theory despite the fact that human reasoning does not always conform to these laws. For this reason we have seen the recent emergence of models based on an alternative probabilistic framework drawn from quantum theory. These quantum models show promise in addressing cognitive phenomena that have proven recalcitrant to modeling by means of classical probability theory. This review compares and contrasts probabilistic models based on Bayesian or classical versus quantum principles, and highlights the advantages and disadvantages of each approach.

The only experiential time is NOW. Our phenomenal minds spring into existence at increments of conscious instants. The sequence of these Nows constitutes our “stream” of consciousness. D-Theory of Time, or Digital Presentism, is predicated on reversible quantum computing at large and gives us a coherent theoretical framework on the nature of time. In the absence of observers, the arrow of time doesn’t exist — there’s no cosmic flow of time. Instead, each conscious observer is a digital pattern flowing within a multidimensional matrix.

Based on the Cybernetic Theory of Mind by evolutionary cyberneticist Alex Vikoulov that he defends in his magnum opus The Syntellect Hypothesis: Five Paradigms of the Mind’s Evolution, comes a newly-released documentary Consciousness: Evolution of the Mind.

This film, hosted by the author of the book from which the narrative is derived, is now available for viewing on demand on Vimeo, Plex, Tubi, Xumo, Social Club TV and other global networks with its worldwide premiere aired on June 8 2021. This is a futurist’s take on the nature of consciousness and reverse engineering of our thinking in order to implement it in cybernetics and advanced AI systems.

According to Klaus Schwab, the founder and executive chair of the World Economic Forum (WEF), the 4-IR follows the first, second, and third Industrial Revolutions—the mechanical, electrical, and digital, respectively. The 4-IR builds on the digital revolution, but Schwab sees the 4-IR as an exponential takeoff and convergence of existing and emerging fields, including Big Data; artificial intelligence; machine learning; quantum computing; and genetics, nanotechnology, and robotics. The consequence is the merging of the physical, digital, and biological worlds. The blurring of these categories ultimately challenges the very ontologies by which we understand ourselves and the world, including “what it means to be human.”

The specific applications that make up the 4-R are too numerous and sundry to treat in full, but they include a ubiquitous internet, the internet of things, the internet of bodies, autonomous vehicles, smart cities, 3D printing, nanotechnology, biotechnology, materials science, energy storage, and more.

While Schwab and the WEF promote a particular vision for the 4-IR, the developments he announces are not his brainchildren, and there is nothing original about his formulations. Transhumanists and Singularitarians (or prophets of the technological singularity), such as Ray Kurzweil and many others, forecasted these and more revolutionary developments,. long before Schwab heralded them. The significance of Schwab and the WEF’s take on the new technological revolution is the attempt to harness it to a particular end, presumably “a fairer, greener future.”

Lightspeed is the fastest velocity in the universe. Except when it isn’t. Anyone who’s seen a prism split white light into a rainbow has witnessed how material properties can influence the behavior of quantum objects: in this case, the speed at which light propagates.

Electrons also behave differently in materials than they do in , and understanding how is critical for scientists studying and engineers looking to develop new technologies. “An electron’s wave nature is very particular. And if you want to design devices in the future that take advantage of this quantum mechanical nature, you need to know those wavefunctions really well,” explained co-author Joe Costello, a UC Santa Barbara graduate student in condensed matter physics.

In a new paper, co-lead authors Costello, Seamus O’Hara and Qile Wu and their collaborators developed a method to calculate this wave nature, called a Bloch wavefunction, from physical measurements. “This is the first time that there’s been experimental reconstruction of a Bloch wavefunction,” said senior author Mark Sherwin, a professor of condensed matter physics at UC Santa Barbara. The team’s findings appear in the journal Nature, coming out more than 90 years after Felix Bloch first described the behavior of electrons in crystalline solids.

I wonder what the Sputnik moment would need to be in the AI race to trigger panic AI research spending in the US. It would probably have to be China hitting AGI first.

Native CPU and accelerator architectures that have been in play on China’s previous large systems have been stepped up to make China first to exascale on two fronts.

The National Supercomputing Center in Wuxi is set to unveil some striking news based on quantum simulation results on a forthcoming homegrown Sunway supercomputer.

The news is notable not just for the calculations, but the possible architecture and sheer scale of the new machine. And of course, all of this is notable because the United States and China are in a global semiconductor arms race and that changes the nature of how we traditionally compare global supercomputing might. We have been contemplating China’s long road to datacenter compute independence, of which HPC is but one workload, and these are some big steps.

A new analytical technique is able to provide hitherto unattainable insights into the extremely rapid dynamics of biomolecules. The team of developers, led by Abbas Ourmazd from the University of Wisconsin–Milwaukee and Robin Santra from DESY, is presenting its clever combination of quantum physics and molecular biology in the scientific journal Nature. The scientists used the technique to track the way in which the photoactive yellow protein (PYP) undergoes changes in its structure in less than a trillionth of a second after being excited by light.

“In order to precisely understand biochemical processes in nature, such as photosynthesis in certain bacteria, it is important to know the detailed sequence of events,” Santra says. “When light strikes photoactive proteins, their spatial structure is altered, and this structural change determines what role a protein takes on in nature.”

Until now, however, it has been almost impossible to track the exact sequence in which structural changes occur. Only the initial and final states of a molecule before and after a reaction can be determined and interpreted in theoretical terms. “But we don’t know exactly how the energy and shape changes in between the two,” says Santra. “It’s like seeing that someone has folded their hands, but you can’t see them interlacing their fingers to do so.”

Isaac Nape, an emerging South African talent in the study of quantum optics, is part of a crack team of Wits physicists who led an international study that revealed the hidden structures of quantum entangled states. The study was published in the renowned scientific journal, Nature Communications.

Nape is pursuing his PhD at Wits University and focuses on harnessing structured patterns of light for high dimensional information encoding and decoding for use in quantum communication.

Earlier this year he scooped up two awards at the South African Institute of Physics (SAIP) conference to add to his growing collection of accolades in the field of optics and photonics. He won the award for ‘Best PhD oral presentation in applied physics’, and jointly won the award for ‘Best PhD oral presentation in photonics’.

‘’A research team with Denmark’s University of Copenhagen has designed the world’s first quantum computing system that allows for simultaneous operation of all its qubits without threatening quantum coherence.’’

A team of researchers from Denmark have achieved a breakthrough in quantum computing by designing a system that allows for all qubits to be manipulated and observed — at the same time — without compromising the system’s quantum coherence.
