D-Wave announces Leap 2, its cloud service for quantum computing applications

D-Wave today launched its next-generation quantum computing platform available via its Leap quantum cloud service. The company calls Advantage “the first quantum computer built for business.” In that vein, D-Wave today also debuted Launch, a jump-start program for businesses that want to begin building hybrid quantum applications.

“The Advantage quantum computer is the first quantum computer designed and developed from the ground up to support business applications,” D-Wave CEO Alan Baratz told VentureBeat. “We engineered it to be able to deal with large, complex commercial applications and to be able to support the running of those applications in production environments. There is no other quantum computer anywhere in the world that can solve problems at the scale and complexity that this quantum computer can solve problems. It really is the only one that you can run real business applications on. The other quantum computers are primarily prototypes. You can do experimentation, run small proofs of concept, but none of them can support applications at the scale that we can.”

D-Wave Systems’ Leap 2 is a quantum cloud service to help businesses and developers build and deploy quantum computing applications.

Theology of Digital Physics: The Universe of Conscious Minds

#DigitalTheology #TheologyofDigitalPhysics #PhenomenalConsciousness #CosmicSelf #HolographicPrinciple #DigitalPhysics #theology #pantheism #consciousness

Since we live in a world which isn’t random, but organized at every level, a role for consciousness seems unavoidable. The ‘digital theologian’ shows us compelling evidence from quantum mechanics, mathematics and computer sciences, which not only aligns with a philosophical worldview of the Primacy of Consciousness, but which also assigns a role to information as its modus operandi.

It is quantum mechanics which appears to connect the Universe as a whole to consciousness. A whole, which is more than the sum of its parts and irreducible to mere assumptions deriving from the anatomizing dissection into mental confabulations. Drawing from the holographic principle, perceptroniums and noocentrism, Alex provides crucial keys to unlock the mystery of consciousness to show us how our local consciousness can arise from a non-local cosmic consciousness network.

Carefully building his fortress of arguments, Alex gathers his building bricks from various areas of scientific exploration, ranging from the role of language and tools in the development of our consciousness, the physics of time and epigenetics. Traditional Darwinism and reductive materialism become so challenged, that we become bound to agree with Terence McKenna’s statement that “object fetishism is completely bankrupt.” All these threads are then skillfully woven into the irresistible attractor and only logical conclusion, or Digital Pantheism and Omega Point Cosmology. And with this thus synthesized Apotheosis, Vikoulov brings the architecture of his chef-d’oeuvre to full fruition.

Neuroscience research shows we reorganize our memory based on how we will use it later

A recent international scientific study published in the journal PLOS ONE has shown that the way the brain stores temporary information is different depending on the use one might give to that information in the future.

The research analysed the brain activity of 14 participants through functional magnetic resonance imaging while they were performing simple visual memory tasks on a computer screen. Differences in their brain activity patterns were found between participants who had to answer by communicating verbally or by pressing a button.

The memory that is under study is designated “working memory” and is used at all times. It is the type of memory that allows us to memorise a phone number or a license plate and use that information after (or not). This information is used and processed and, if it proves to be important, stored in the long-term memory.

Nanostructures with a unique property

Nanoscale vortices known as skyrmions can be created in many magnetic materials. For the first time, researchers at PSI have managed to create and identify antiferromagnetic skyrmions with a unique property: critical elements inside them are arranged in opposing directions. Scientists have succeeded in visualizing this phenomenon using neutron scattering. Their discovery is a major step towards developing potential new applications, such as more efficient computers. The results of the research are published today in the journal Nature.

Whether a material is magnetic depends on the spins of its atoms. The best way to think of spins is as minute bar magnets. In a where the atoms have fixed positions in a lattice, these spins can be arranged in criss-cross fashion or aligned all in parallel like the spears of a Roman legion, depending on the individual material and its state.

Under certain conditions it is possible to generate tiny vortices within the corps of spins. These are known as skyrmions. Scientists are particularly interested in skyrmions as a key component in future technologies, such as more efficient data storage and transfer. For example, they could be used as memory bits: a could represent the digital one, and its absence a digital zero. As skyrmions are significantly smaller than the bits used in conventional storage media, data density is much higher and potentially also more energy efficient, while read and write operations would be faster as well. Skyrmions could therefore be useful both in classical data processing and in cutting-edge quantum computing.

A Quantum Molecular Assembler

Researchers have created a molecule in a single, precisely characterized quantum state by merging two carefully prepared atoms.

Researchers have demonstrated a quantum molecular assembler—a device that takes individual atoms as inputs and merges them into a molecule in a desired quantum state. The team used lasers to trap and cool one sodium (Na) atom and one cesium (Cs) atom, bring them together, and merge them into an NaCs molecule in a specific quantum state. Such a quantum-controlled molecule is a promising building block for quantum computers and could help researchers study the quantum details of chemical reactions.

Quantum Enhanced Atomic Force Microscopy: Squeezed Light Reduces Noise

Researchers at the Department of Energy’s Oak Ridge National Laboratory used quantum optics to advance state-of-the-art microscopy and illuminate a path to detecting material properties with greater sensitivity than is possible with traditional tools.

“We showed how to use squeezed light – a workhorse of quantum information science – as a practical resource for microscopy,” said Ben Lawrie of ORNL’s Materials Science and Technology Division, who led the research with Raphael Pooser of ORNL’s Computational Sciences and Engineering Division. “We measured the displacement of an atomic force microscope microcantilever with sensitivity better than the standard quantum limit.”

Unlike today’s classical microscopes, Pooser and Lawrie’s quantum microscope requires quantum theory to describe its sensitivity. The nonlinear amplifiers in ORNL’s microscope generate a special quantum light source known as squeezed light.

Human genetics: A look in the mirror

Who are we? Where did we come from? How did we get here? Throughout the ages, humans have sought answers to these questions, pursuing wisdom through religion, philosophy, and eventually science. Evolutionary analyses published by Genome Biology and Evolution (GBE) allow us to peer into the mirror and better understand ourselves as a species, bringing us closer than ever to uncovering the answers to these long-held questions. GBE’s latest virtual issue on human genetics highlights some of the most exciting research published in the journal within the last year and a half, demonstrating the wide variety of evolutionary approaches to this avenue of research as well as a number of fascinating insights into our own biology.

Taking over a decade to complete, the original Human Genome Project cost nearly $3 billion and involved the collective effort of hundreds of scientists. Since then, advances in sequencing technology have resulted in an explosion in and genomics research, with an estimated one million human genomes sequenced to date. While this wealth of data has the potential to answer some of our most fundamental questions, unlocking its mysteries has necessitated the invention of new analytic and computational methods and the integration of techniques and ideas from diverse biological sciences, including physiology, anatomy, medicine, , bioinformatics, and computational, molecular, and evolutionary biology.

A key area of investigation involves identifying ways in which humans differ from other primates—in other words, what makes us human? Several studies published over the last 18 months suggest that part of the answer may be found in transcriptional regulation and changes in gene expression. Edsall et al. (2019) evaluated differences in chromatin accessibility, which impacts access of the transcriptional machinery to the DNA, across five primates including humans. They found high levels of differentiation across species, as well as classes of sites that differed based on selection, genomic location, and cell type specificity. More specifically, Swain-Lenz et al. (2019) found that differences in chromatin accessibility near genes involved in lipid metabolism may provide a mechanistic explanation for the higher levels of body fat observed in humans compared to other primates.
