▶ "Design of a Superconducting Quantum Computer" - Talk by John Martinis

Superconducting quantum computing is now at an important crossroad, where "proof of concept" experiments involving small numbers of qubits can be transitioned to more challenging and systematic approaches that could actually lead to building a quantum computer. Our optimism is based on two recent developments: a new hardware architecture for error detection based on "surface codes" [1], and recent improvements in the coherence of superconducting qubits [2]. I will explain how the surface code is a major advance for quantum computing, as it allows one to use qubits with realistic fidelities, and has a connection architecture that is compatible with integrated circuit technology. Additionally, the surface code allows quantum error detection to be understood using simple principles. I will also discuss how the hardware characteristics of superconducting qubits map into this architecture, and review recent results that suggest gate errors can be reduced to below that needed for the error detection threshold.

Dark matter looks more and more likely after new gamma-ray analysis

Dark matter looks more and more likely after new gamma-ray analysis | Pahndeepah Perceptions | Scoop.it
Scientists describe as 'extremely interesting' new analysis that makes case for gamma rays tracing back to Wimp particles

 

Not long after the Fermi Gamma-ray SpaceTelescope took to the sky in 2008, astrophysicists noticed that it was picking up a steady rain of gamma rays pouring outward from the center of the Milky Way galaxy.

 

This high-energy radiation was consistent with the detritus of annihilating dark matter, the unidentified particles that constitute 84% of the matter in the universe and that fizzle upon contact with each other, spewing other particles as they go. If the gamma rays did in fact come from dark matter, they would reveal its identity, resolving one of the biggest mysteries in physics. But some argued that the gamma rays could have originated from another source.

 

Now a new analysis of the signal claims to rule out all other plausible explanations and makes the case that the gamma rays trace back to a type of particle that has long been considered the leading dark matter candidate – a weakly interacting massive particle, or Wimp. Meanwhile, a more tentative X-ray signal reported in two other new studies suggests the existence of yet another kind of dark matter particle called a sterile neutrino.

 

In the new gamma-ray analysis, which appeared February 27 on the scientific preprint site arXiv.org, Dan Hooper and his collaborators used more than five years' worth of the cleanest Fermi data to generate a high-resolution map of the gamma-ray excess extending from the center of the galaxy outward at least 10 angular degrees, or 5,000 light-years, in all directions.

 

"The results are extremely interesting," said Kevork Abazajian, an associate professor of physics and astronomy at the University of California, Irvine. "The most remarkable part of the analysis is that the signal follows the shape of the dark matter profile out to 10 degrees," he said, explaining that it would be "very difficult to impossible" for other sources to mimic this predicted dark matter distribution over such a broad range.

 

The findings do not constitute a discovery of dark matter, the scientists said, but they prepare the way for an upcoming test described by many researchers as a "smoking gun": If the gamma-ray excess comes from annihilating Wimps, and not conventional astrophysical objects, then the signal will also be seen emanating from dwarf galaxies that orbit the Milky Way – diffuse objects that are rich in dark matter but not in other high-energy photon sources such as pulsars, rotating neutron stars that have been floated as alternative explanations for the excess.

The more we know about this place we call "the universe" the more likely we'll be able to understand ourselves and to put our minds to ease about a great many of our pressing questions.

 

The more we know about this place, the more likely it will be that we're able to alleviate suffering, misery and, hopefully, bring a greater quality of life and sense of peace to all of our minds.

 

Assuming that each of our particular minds are willing and able to accept the truths of this world in the first place.

 

Think about it.

Keith Wayne Brown's insight:
"...The journey of the celebrity artist or entrepreneur is today the most culturally significant journey people make from low status and high vulnerability to the reverse. Artists and entrepreneurs who become rich and famous are our best guides to the dangerous way that former outcasts can become champions of an all-encompassing economic and political system run by elites who promise total health, total safety, and total control. This tension between outcast and overlord is at the heart of our sweeping change into a tech-driven, spiritually infused economy. The fate of free enterprise—and freedom itself—hangs in the balance..."

How long before an article appears in Slate telling people all across America that they’re making toast all wrong? How long before the backlash sets in?'

Fish appear to be absent from the ocean's greatest depths due to biochemistry

Fish appear to be absent from the ocean's greatest depths due to biochemistry | Pahndeepah Perceptions | Scoop.it
The ability of deep sea fish to plumb new depths may be constrained by biochemistry, new research by an international team has found.

 

Fish appear to be absent from the ocean's greatest depths, the trenches from 8,400–11,000 m. The reason is unknown, but hydrostatic pressure is suspected. We propose that the answer is the need for high levels of trimethylamine oxide (TMAO, common in many marine animals), a potent stabilizer capable of counteracting the destabilization of proteins by pressure. TMAO is known to increase with depth in bony fishes (teleosts) down to 4,900 m. By capturing the world's second-deepest known fish, the hadal snailfish Notoliparis kermadecensis from 7,000 m, we find that they have the highest recorded TMAO contents, which, moreover, yield an extrapolated maximum for fish at about 8,200 m. This is previously unidentified evidence that biochemistry may constrain depth for a large taxonomic group.

Perfect memory, enhanced vision, an expert golf swing: The future of brain implants

Perfect memory, enhanced vision, an expert golf swing: The future of brain implants | Pahndeepah Perceptions | Scoop.it
How soon can we expect to see brain implants for perfect memory, enhanced vision, hypernormal focus or an expert golf swing? We're closer than you might think.

 

What would you give for a retinal chip that let you see in the dark or for a next-generation cochlear implant that let you hear any conversation in a noisy restaurant, no matter how loud? Or for a memory chip, wired directly into your brain's hippocampus, that gave you perfect recall of everything you read? Or for an implanted interface with the Internet that automatically translated a clearly articulated silent thought ("the French sun king") into an online search that digested the relevant Wikipedia page and projected a summary directly into your brain?

 

Science fiction? Perhaps not for very much longer. Brain implants today are where laser eye surgery was several decades ago. They are not risk-free and make sense only for a narrowly defined set of patients—but they are a sign of things to come.

 

Unlike pacemakers, dental crowns or implantable insulin pumps, neuroprosthetics—devices that restore or supplement the mind's capacities with electronics inserted directly into the nervous system—change how we perceive the world and move through it. For better or worse, these devices become part of who we are.

 

Neuroprosthetics aren't new. They have been around commercially for three decades, in the form of the cochlear implants used in the ears (the outer reaches of the nervous system) of more than 300,000 hearing-impaired people around the world. Last year, the Food and Drug Administration approved the first retinal implant, made by the company Second Sight.

Both technologies exploit the same principle: An external device, either a microphone or a video camera, captures sounds or images and processes them, using the results to drive a set of electrodes that stimulate either the auditory or the optic nerve, approximating the naturally occurring output from the ear or the eye.

Elysia chlorotica, a solar-powered sea slug is an energy-efficient gene thief

Elysia chlorotica, a solar-powered sea slug is an energy-efficient gene thief | Pahndeepah Perceptions | Scoop.it

Elysia chlorotica is a “solar-powered” marine sea slug that sequesters and retains photosynthetically active chloroplasts from the algae it eats and, remarkably, has incorporated algal genes into its own genetic code. It is emerald green in color often with small red or white markings, has a slender shape typical of members of its genus, and parapodia (lateral "wings") that fold over its body in life. This sea slug is unique among animals to possess photosynthesis-specific genes and is an extraordinary example of symbiosis between an alga and mollusc as well as a genetic chimera of these two organisms.

 

To obtain algal chloroplasts Elysia chlorotica slugs use their radula (tooth) to pierce a filament of the alga Vaucheria litorea and suck out its contents. The ingested algal cytoplasm and nuclei move through the gut but algal chloroplasts are trapped and concentrated in vacuoles along branches of the digestive tract. While inside an algal cell, functional chloroplasts use proteins encoded by their own genes as well as others encoded by genes within the algal nucleus. Within a sea slug, however, isolated chloroplasts can not receive proteins from the algal genome. Remarkably, these chloroplasts remain functional anyway because the slug genome includes the algal genes necessary for plastid function. Elysia chlorotica probably gained these algal genes through lateral (or horizontal) gene transfer. One possible vector is a virus that infects the sea slug and carried pieces of algal DNA (Pierce et al., 2003).
