In this video, D-Wave Systems Founder Eric Ladizinsky presents: The Coming Quantum Computing Revolution.
“Despite the incredible power of today’s supercomputers, there are many complex computing problems that can’t be addressed by conventional systems. Our need to better understand everything, from the universe to our own DNA, leads us to seek new approaches to answer the most difficult questions. While we are only at the beginning of this journey, quantum computing has the potential to help solve some of the most complex technical, commercial, scientific, and national defense problems that organizations face. We expect that quantum computing will lead to breakthroughs in science, engineering, modeling and simulation, financial analysis, optimization, logistics, and national defense applications.”

A Quantum Computing-Dominated World Is Coming In Less Than 10 Years, Says CEO Of Acronis
Posted by Karen Hurst in categories: quantum physics, security, solar power, supercomputing, sustainability
I told folks this; I see another one from Google has joined the QC less than 10 year club. My guess is more likely less than 7 years.
A seminal moment in the quantum technology field just happened: Google’s team of scientists have simulated a hydrogen molecule from its quantum computers, a breakthrough that suggests it could “simulate even larger chemical systems,” writes one of Google Quantum’s engineers, Ryan Rabbush. The search engine’s achievement underscores the technology’s potential as Rabbush posits it can “revolutionize the design of solar cells, industrial catalysts, batteries, flexible electronics, medicines, materials and more.”
As advances in such supercomputers continue, investment and research in this field gathers greater momentum as Google, Alibaba, Baidu, Amazon and other tech giants and governments too are racing to develop this technology. Recently, the European Commission allocated €1 billion to research, incubate and invest in quantum technologies. Meanwhile Google last month made headlines about testing its quantum security to shield its Chrome browser.

China rockets to top of supercomputing charts with homegrown tech
Posted by Karen Hurst in categories: biotech/medical, supercomputing
Lookout world Chine Tech is rising and nothing or no one will stop it now. The real question is how soon with the world’s tech valley hub be in China? The US has enjoyed for many decades being the world’s top technology center. However, China for the past 20+ years has been executing their world footprint in owning the title as the top global economic power. In the past we have seen them take over consumer goods manufacturing, pharma (especially generic drugs), and the latest is tech. Wonder what is next?
TOKYO — China has jumped to the front ranks of the supercomputing powers, with its Sunway TaihuLight, powered by domestically developed chips, recently recognized as the fastest computer in the world.
In its debut on the Top500 list of the world’s fastest supercomputers in June, the Sunway TaihuLight overwhelmed such rivals as the Tianhe-2, a Chinese supercomputer powered by Intel chips that has claimed the No. 1 spot on the past six Top500 lists. Furthermore, it was the first time for China to surpass the U.S. in the total number of systems on the list.

Quantum computing is getting closer
Posted by Karen Hurst in categories: encryption, information science, quantum physics, supercomputing
Electronic computer technology has moved from valves to transistors to progressively more complex integrated circuits and processor designs, with each change bringing higher levels of performance. Now the advent of quantum computers promises a huge step increase in processor performance to solve certain types of problems.
Quantum computers are much faster than the world’s fastest supercomputers for some applications. In 1994 Peter Shor, an applied mathematician at Bell Laboratories, gave the encryption world a shock when he demonstrated an algorithm showing that quantum computers could threaten conventional prime number based encryption methods.
If an adversary conducts successful espionage raids on encrypted information stored in present technology computer installations, possibly through a compromised or issue-motivated individual who transfers it to portable media, it could become vulnerable to decryption by that rival’s quantum computers.

Oxide-confined leaky vertical-cavity surface-emitting lasers for single-mode operation
Posted by Karen Hurst in category: supercomputing
Lateral photonic integration of oxide-confined leaky vertical-cavity surface-emitting lasers enables their application in data communications and sensing.
Vertical-cavity surface-emitting lasers (VCSELs) that operate at 850nm and are based on oxide-confined apertures are widely used in optical interconnects in data centers, supercomputers, wireless backbone networks, and consumer applications.1 As the processor productivity in these applications increases, it is necessary to continuously improve performance and scale transmission speeds accordingly. In recent years, developers have produced a generation of devices capable of transmitting 40Gb/s at moderate current densities,2, 3 and they have recently demonstrated 54Gb/s non-return-to-zero transmission through 2.2km of multimode fiber.4 Now, 108Gb/s per wavelength transmission can be realized over 100–300m of multimode fiber through the use of advanced modulation formats: discrete multi-tone,5 multiCAP,6 and PAM4.

Getting light in shape with metamaterials
Posted by Karen Hurst in categories: nanotechnology, quantum physics, supercomputing
A team built a specialized, layered structure with tiny metallic cavities that improves the light conversion efficiency by orders of magnitude.
Artist’s rendering of an incident laser beam (top of the figure) illuminating an array of nanoscale gold resonators on the surface of a “quantum well” semiconductor (slab in figure). (A quantum well is a thin layer that can restrict the movement of electrons to that layer.) The incoming laser beam interacts with the array and the quantum wells and is converted into two new laser beams with different wavelengths. Changing the size, shape, and arrangement of the resonators can be used for beam focusing, beam steering, or control of the beam’s angular momentum. (Image: Sandia National Laboratories)

Moving beyond semiconductors for next-generation electric switches
Posted by Karen Hurst in categories: energy, mathematics, mobile phones, quantum physics, supercomputing
Computers use switches to perform calculations. A complex film with “quantum wells”—regions that allow electron motion in only two dimensions—can be used to make efficient switches for high-speed computers. For the first time, this oxide film exhibited a phenomenon, called resonant tunneling, in which electrons move between quantum wells at a specific voltage. This behavior allowed an extremely large ratio (about 100,000:1) between two states, which can be used in an electronic device as an ON/OFF switch to perform mathematical calculations (Nature Communications, “Resonant tunneling in a quantum oxide superlattice”).
Efficient control of electron motion can be used to reduce the power requirements of computers. “Quantum wells” (QW) are regions that allow electron motion in only two dimensions. The lines (bottom) in the schematic show the probability of finding electrons in the structure. The structure is a complex oxide (top) with columns (stacked blue dots corresponding to an added element) where the electrons are free to move in only two dimensions. This is a special type of quantum well called a two-dimensional electron gas (2DEG). (Image: Ho Nyung Lee, Oak Ridge National Laboratory)
