How To Get Better At Quantum Computing: Make A Game Of It

Posted by in categories: computing, entertainment, internet, quantum physics

Creative approach and I like it. I advise IT leaders, developers, architects, etc. to start learning as much as they can about Quantum Technology because technology in the next 6 to 7 years will begin the accelerated adoption of this technology and at that point it will be too late for folks in tech to catch up. Now is the time to learn and keep track of the progression of this technology as well as understand where and how this technology can be leveraged earlier in various areas of the infrastructure, devices, and even in industry.


Researchers gave internet users games that simulate quantum physics experiments, and internet users gave the researchers more elegant solutions.

Long-range secure quantum communication system developed

Posted by in categories: business, encryption, finance, information science, quantum physics, security

Scientists from ITMO University in Saint Petersburg, Russia have enabled the longer distance (250 Kilos) of secured data transmission occur via Quantum. Nice; and should be a wake up call to the US as well on advancing their efforts more.


A group of scientists from ITMO University in Saint Petersburg, Russia has developed a novel approach to the construction of quantum communication systems for secure data exchange. The experimental device based on the results of the research is capable of transmitting single-photon quantum signals across distances of 250 kilometers or more, which is on par with other cutting edge analogues. The research paper was published in the Optics Express journal.

Information security is becoming more and more of a critical issue not only for large companies, banks and defense enterprises, but even for small businesses and individual users. However, the data encryption algorithms we currently use for protecting our data are imperfect — in the long-term, their logic can be cracked. Regardless of how complex and intricate the algorithm is, getting round it is just the matter of time.

Three-way battles in the quantum world

Posted by in categories: cybercrime/malcode, particle physics, quantum physics, robotics/AI

One thing about Quntum; nothing ever stays consistent. Why it’s loved & hated by Cyber Security enthusiasts as well as AI engineers.


When water in a pot is slowly heated to the boil, an exciting duel of energies takes place inside the liquid. On the one hand there is the interaction energy that wants to keep the water molecules together because of their mutual attraction. On the other hand, however, the motional energy, which increases due to heating, tries to separate the molecules. Below the boiling point the interaction energy prevails, but as soon as the motional energy wins the water boils and turns into water vapour. This process is also known as a phase transition. In this scenario the interaction only involves water molecules that are in immediate proximity to one another.

Advances in quantum communication will come from investment in hybrid technologies explain Stefano Pirandola and Samuel L

Posted by in categories: computing, internet, quantum physics

The question is what does Stefano Pirandola and Samuel L. Braunstein consider “hybrid” when it comes to QC? In much of the Quantum research today only shows us things like “synthetic diamonds”, etc. are added to stablize data storage and transmissions not much else.

Supercomputers Aid in Quantum Materials Research

Lov’n Quantum Espresso


Researchers use specialized software such as Quantum ESPRESSO and a variety of HPC software in conducting quantum materials research. Quantum ESPRESSO is an integrated suite of computer codes for electronic-structure calculations and materials modeling, based on density-functional theory, plane waves and pseudo potentials. Quantum ESPRESSO is coordinated by the Quantum ESPRESSO Foundation and has a growing world-wide user community in academic and industrial research. Its intensive use of dense mathematical routines makes it an ideal candidate for many-core architectures, such as the Intel Xeon Phi coprocessor.

The Intel Parallel Computing Centers at Cineca and Lawrence Berkeley National Lab (LBNL) along with the National Energy Research Scientific Computing Center (NERSC) are at the forefront in using HPC software and modifying Quantum ESPRESSO (QE) code to take advantage of Intel Xeon processors and Intel Xeon Phi coprocessors used in quantum materials research. In addition to Quantum ESPRESSO, the teams use tools such as Intel compilers, libraries, Intel VTune and OpenMP in their work. The goal is to incorporate the changes they make to Quantum ESPRESSO into the public version of the code so that scientists can gain from the modification they have made to improve code optimization and parallelization without requiring researchers to manually modify legacy code.

Can optical technology solve the high performance computing energy conundrum?

Posted by in categories: energy, quantum physics, supercomputing

Another pre-Quantum Computing interim solution for super computing. So, we have this as well as Nvidia’s GPU. Wonder who else?


In summer 2015, US president Barack Obama signed an order intended to provide the country with an exascale supercomputer by 2025. The machine would be 30 times more powerful than today’s leading system: China’s Tianhe-2. Based on extrapolations of existing electronic technology, such a machine would draw close to 0.5GW – the entire output of a typical nuclear plant. It brings into question the sustainability of continuing down the same path for gains in computing.

One way to reduce the energy cost would be to move to optical interconnect. In his keynote at OFC in March 2016, Professor Yasuhiko Arakawa of University of Tokyo said high performance computing (HPC) will need optical chip to chip communication to provide the data bandwidth for future supercomputers. But digital processing itself presents a problem as designers try to deal with issues such as dark silicon – the need to disable large portions of a multibillion transistor processor at any one time to prevent it from overheating. Photonics may have an answer there as well.

The Ultimate Debate – Interconnect Offloading Versus Onloading

Posted by in categories: computing, quantum physics

When I read articles like this one; I wonder if folks really fully understand the full impact of what Quantum brings to all things in our current daily lives.


The high performance computing market is going through a technology transition – the Co-Design transition. As has already been discussed in many articles, this transition has emerged in order to solve the performance bottlenecks of today’s infrastructures and applications, performance bottlenecks that were created by multi-core CPUs and the existing CPU-centric system architecture.

How are multi-core CPUs the source for today’s performance bottlenecks? In order to understand that, we need to go back in time to the era of single-core CPUs. Back then, performance gains came from increases in CPU frequency and from the reduction of networking functions (network adapter and switches). Each new generation of product brought faster CPUs and lower-latency network adapters and switches, and that combination was the main performance factor. But this could not continue forever. The CPU frequency could not be increased any more due to power limitations, and instead of increasing the speed of the application process, we began using more CPU cores in parallel, thereby executing more processes at the same time. This enabled us to continue improving application performance, not by running faster, but by running more at the same time.
