IBM Scientists Measure Heat-Transfer through Single Atoms

Posted by in categories: computing, nanotechnology, particle physics, quantum physics

Published today, using a technique which looks like trampoline, IBM scientists have measured the thermal conductance of metallic quantum point contacts made of gold down to the single-atom level at room temperature for the first time.

As everything scales to the nanoscale, heat – more precisely, the loss of it – becomes an issue in device reliability. To address this, last year, IBM scientists in Zurich and students from ETH Zurich published and patented a technique to measure the temperature of these nano-sized objects at and below 10 nanometer – a remarkable achievement. They called the novel technique scanning probe thermometry (video) and it provided engineers, for the first time, with the ability to map heat loss across a chip, and, more importantly, map heat loss down to the single device level and to map temperature distributions.

Collaboration Prepares DTU for Quantum Future

Posted by in categories: business, computing, encryption, quantum physics

I actually had a person recently state quantum was a fad; boy were they ever wrong.

During the next ten years, quantum technologies will become part of and revolutionize our everyday lives in the form of computers, sensors, encryption, and much more—and in a way that can be difficult for us to comprehend.

Businesses will also boost both their research and development activities in this area.

This New Liquid Crystal Can Triple the Sharpness of Tv and Computer Screens

Posted by in categories: computing, electronics

Scientists have invented a new type of liquid crystal that allows tv and computer manufacturers to pack three times as many pixels into the same area of screen, while reducing the amount of power required to run the device.

This new type of blue-phase liquid crystal is so effective because it bypasses the colour filters used in current screen technology. This change alone reduces the amount of energy lost during light transmission by more than 40 percent.

“Today’s Apple Retina displays have a resolution density of about 500 pixels per inch,” says one of the team, physicist Shin-Tson Wu from University of Central Florida.

Scientists Chasing the Dream of Quantum Computing

Posted by in categories: computing, finance, neuroscience, quantum physics

The bottom-line why folks are investing so much in QC is frankly because it means you will be behind everyone else who has adopted a superior infrastructure. As a consumer, if I can use my private information to secure a loan or access my medical information without fear of exposure of my information as well as performance of my online media and other online services are 100 times faster than any known network service to date; it doesn’t take a brain surgeon to know what I will do,

And, banks, trading houses, etc. know this.

Thanks to the collaborative effort of an international team of scientists led by Professor Winfried Hensinger of the University of Sussex in UK, the world may have gotten one step closer to building the most powerful computer ever — a large-scale quantum computer capable of solving ultra-complex problems that will take a regular computer billions of years to solve.

Race is on among tech firms to build a computing ‘oracle’

Posted by in categories: computing, quantum physics

For most people to understand Quantum and its importance and potential for various areas of our lives; means pushing away everything that you have known about technology & natural sciences (biology, geology, environmental, etc.). Those of us who have been doing research and development in quantum have had to rethink/ rewire our thoughts and ideas about what is possible and what is not possible in medicine, technology, etc.

Once you begin understanding this concept then you begin to understand more the impact and possibilities of a quantum enriched world.

In ancient times, it would have been called an oracle – a source of instant insight on the most perplexing problems. Now, scientists are closing in on making a device capable of such feats.

Scientists Simulate a New Material That Could Be Even Weirder Than Graphene

Posted by in categories: computing, nanotechnology, particle physics

We all love graphene — the one-atom-thick sheets of carbon aren’t just super flexible, harder than diamond, and stronger than steel, they’ve also recently become superconductors in their own right.

But it’s not the only over-achieving nanomaterial out there. Researchers have just simulated a stretched out, one-dimensional (1D) chain of boron, predicting that the material could have even weirder properties than graphene.

Protecting quantum computing networks against hacking threats

Posted by in categories: computing, quantum physics, security

Wish these guys a lot of luck; however, they need to hurry up soon as China is already had a head start with QC.

As we saw during the 2016 US election, protecting traditional computer systems, which use zeros and ones, from hackers is not a perfect science. Now consider the complex world of quantum computing, where bits of information can simultaneously hold multiple states beyond zero and one, and the potential threats become even trickier to tackle. Even so, researchers at the University of Ottawa have uncovered clues that could help administrators protect quantum computing networks from external attacks.

“Our team has built the first high-dimensional quantum cloning machine capable of performing quantum hacking to intercept a secure quantum message,” said University of Ottawa Department of Physics professor Ebrahim Karimi, who holds the Canada Research Chair in Structured Light. “Once we were able to analyze the results, we discovered some very important clues to help protect quantum computing networks against potential hacking threats.”

Quantum RAM: Modelling the big questions with the very small

Posted by in categories: climatology, computing, finance, quantum physics, singularity, sustainability

Nice write up. What is interesting is that most folks still have not fully understood the magnitude of quantum and how as well as why we will see it as the fundamental ingredient to all things and will be key in our efforts around singularity.

When it comes to studying transportation systems, stock markets and the weather, quantum mechanics is probably the last thing to come to mind. However, scientists at Australia’s Griffith University and Singapore’s Nanyang Technological University have just performed a ‘proof of principle’ experiment showing that when it comes to simulating such complex processes in the macroscopic world quantum mechanics can provide an unexpected advantage.

Griffith’s Professor Geoff Pryde, who led the project, says that such processes could be simulated using a “quantum hard drive”, much smaller than the required for conventional simulations.

The next step in nanotechnology

Posted by in categories: computing, nanotechnology

Nearly every other year the transistors that power silicon computer chip shrink in size by half and double in performance, enabling our devices to become more mobile and accessible. But what happens when these components can’t get any smaller? George Tulevski researches the unseen and untapped world of nanomaterials. His current work: developing chemical processes to compel billions of carbon nanotubes to assemble themselves into the patterns needed to build circuits, much the same way natural organisms build intricate, diverse and elegant structures. Could they hold the secret to the next generation of computing?
