Proof Beyond a Reasonable Doubt That Majorana Fermions Exist
Posted by Shailesh Prasad in categories: computing, cosmology, particle physics, quantum physics
Not only could they transform quantum computing, they’re a candidate for dark matter.
A team of Chinese physicists from Shanghai’s Jiaotong University have proof beyond a reasonable doubt of the existence of the Majorana fermion — a special particle that could potentially revolutionize quantum computing.
“The search for this particle is for condensed-matter physicists what the Higgs boson search was for high-energy particle physicists,” said Leonid Rokhinson, an associate professor of physics at Purdue University, who was the first to detect the signature of the fermion in 2012 but was not involved in this study, in a 2012 press release. “It is a very peculiar object because it is a fermion yet it is its own antiparticle with zero mass and zero charge.”

Quantum technologies to revolutionise 21st century — Nobel Laureates discuss at Lindau
Posted by Karen Hurst in categories: computing, economics, quantum physics
Nice read.
Is quantum technology the future of the 21st century? On the occasion of the 66th Lindau Nobel Laureate Meeting, this is the key question to be explored today in a panel discussion with the Nobel Laureates Serge Haroche, Gerardus ’t Hooft, William Phillips and David Wineland. In the following interview, Council Member Professor Rainer Blatt, internationally renowned quantum physicist, recipient of numerous honours, and Scientific Co-Chairman of the 66th Lindau Meeting, talks about what we can expect from the “second quantum revolution”.
Blatt has no doubt: quantum technologies are driving forward a technological revolution, the future impact of which is still unclear. Nothing stands in the way of these technologies becoming the engine of innovations in science, economics and society in the 21st century. Early laboratory prototypes have shown just how vast the potential of quantum technologies is. Specific applications are expected in the fields of metrology, computing and simulations. However, substantial funding is required to advance from the development stage.

However, substantial funding is required to advance from the development stage.
Professor Blatt, the first quantum revolution laid the physical foundations for trailblazing developments such as computer chips, lasers, magnetic resonance imaging and modern communications technology. In the Quantum Manifest published in mid-May, researchers now talk about the advent of a second quantum revolution. What exactly does this mean?

Rising Applications of Quantum Dots in Healthcare Industry to Drive Global Quantum Dots Market
Posted by Karen Hurst in categories: health, nanotechnology, quantum physics, security, solar power, sustainability
Q-Dot demand in Healthcare is predicted to be high.
http://embedded-computing.com/news/rising-quantum-dots-market/#
Quantum Dots Market is driven by increasing demand for energy efficient displays and lighting solutions, North America accounted for largest quantum dots market share, use of quantum dots in solar cells and VLSI design is expected to open new possibilities for quantum dots market.
Quantum dots are semiconducting nanoparticles that range from 1nm to 10nm diameter in size and demonstrate quantum mechanical properties. The peculiarity of quantum dots is that they have ability to unite their semiconductor properties with those of nanomaterials. In addition, tunable nanocrystal size and superior optical properties have made quantum dots attractive semiconducting material for variety of applications in the field of healthcare, optoelectronics, solar energy, and security among others.

Will quantum computing be BlackBerry’s Waterloo?
Posted by Karen Hurst in categories: computing, internet, mobile phones, quantum physics, security
Definitely could see QC being Blackberry’s achilles heal.
WATERLOO — Advances in quantum computing could present a huge challenge to BlackBerry’s biggest competitive advantage — its vaunted security software that has never been hacked.
This seldom talked-about subject was raised recently by John Thompson, the associate vice-president for research at the University of Waterloo. Thompson was listening to a presentation by Mike Wilson, a senior vice-president and chief evangelist for BlackBerry, at a medical technology conference in Kitchener about a month ago.

Atomic-scale simulations predict how to use nanoparticles to increase hydrogen production
Posted by Karen Hurst in categories: computing, particle physics, quantum physics
Awesome!
What if industrial waste water could become fuel? With affordable, long-lasting catalysts, water could be split to produce hydrogen that could be used to power fuel cells or combustion engines.
By conducting complex simulations, scientists showed that adding lithium to aluminum nanoparticles results in orders-of-magnitude faster water-splitting reactions and higher hydrogen production rates compared to pure aluminum nanoparticles. The lithium allowed all the aluminum atoms to react, which increased yields (Nano Letters, “Hydrogen-on-demand using metallic alloy nanoparticles in water”).

No need in supercomputers
Posted by Karen Hurst in categories: business, cybercrime/malcode, information science, particle physics, quantum physics, robotics/AI, singularity, supercomputing
Great that they didn’t have to use a super computer to do their prescribed, lab controlled experiments. However, to limit QC to a super computer and experimental computations only is a big mistake; I cannot stress this enough. QC is a new digital infrastructure that changes our communications, cyber security, and will eventually (in the years to come) provide consumers/ businesses/ and governments with the performance they will need for AI, Biocomputing, and Singularity.
A group of physicists from the Skobeltsyn Institute of Nuclear Physics, the Lomonosov Moscow State University, has learned to use personal computer for calculations of complex equations of quantum mechanics, usually solved with help of supercomputers. This PC does the job much faster. An article about the results of the work has been published in the journal Computer Physics Communications.
Senior researchers Vladimir Pomerantcev and Olga Rubtsova, working under the guidance of Professor Vladimir Kukulin (SINP MSU) were able to use on an ordinary desktop PC with GPU to solve complicated integral equations of quantum mechanics — previously solved only with the powerful, expensive supercomputers. According to Vladimir Kukulin, personal computer does the job much faster: in 15 minutes it is doing the work requiring normally 2–3 days of the supercomputer time.
