Might-power-the-next-generation-of-quantum-computing-4455118/
Scientists have developed a way to mass-produce tiny diamond crystals shaped like needles and threads, which may power next generation of quantum computing. Physicists from the Lomonosov Moscow State University in Russia have described structural peculiarities of micrometre-sized diamond crystals in needle and thread-like shapes, and their interrelation with luminescence features and field electron emission efficiency.
Technological applications of diamonds significantly outweigh their popularity as jewelry, and are increasingly widespread in industry. This is a motivation for researchers busy with elaboration of new diamond synthesis techniques.
Researchers grow needle- and thread-like diamonds
Excellent breakthrough for technology’s future.
Example of diamond crystallites of different shapes, obtained with the help of the technology, worked out in the Lomonosov Moscow State University. There are electron microscopy images of diamond films’ fragments after their oxidation in the air. The material left after the oxidation is represented by needle-like diamond monocrystals of pyramid shape. Credit: Alexander Obraztsov.
Physicists from the Lomonosov Moscow State University have obtained micrometer-sized diamond crystals in the form of a regular pyramid. In cooperation with co-workers from other Russian and foreign research centers, they have also studied the luminescence and electron emission properties of these diamond crystals. The research results have been published in a series of articles in journals including Scientific Reports.
The researchers have described structural peculiarities of micrometer-sized diamond crystals in needle- and thread-like shapes, and their interrelation with luminescence features and field electron emission efficiency. The luminescence properties of such thread-like diamond crystals could be useful in different types of sensors, quantum optical devices, and also for quantum computing.
Quantum Computing and why we need to replace the Internet
More believers; loving it!

As we continue to conduct more of our transactions online, consumers, companies and governments put their faith in encryption to protect their private and sensitive data. Once quantum computing becomes a reality, our current encryption methods will quickly become obsolete as quantum computers will be able to easily crack them.
With companies and governments investing heavily in quantum computing, it seems that a fully functioning quantum computer will become a reality in the not too distant future. A machine like that would have no problem cracking the encryption methods used across the Internet today.
Quantum computers will make today’s internet insecure. Therefore, we should consider replacing the current infrastructure now according to Dr. Vadim Makarov. He heads the Quantum Hacking Lab at the Institute for Quantum Computing at the University of Waterloo in Canada.
Elon Musk gets closer to worldwide internet dream (and all for the same price)
Entrepreneur’s Space X agency files request for $10bn project with the FCC and says internet speeds globally will reach 1Gb/s.
The man who wants to take humans to Mars also wants to connect the whole of planet Earth and bring digital equality across the globe.
Elon Musk’s Space X spacial agency has requested to the US Federal Communications Commission (FCC) authorisation to launch 4,425 satellites which would be used to provide connectivity to the more than 7.2 billion humans on Earth.
Organ-on-chips platform has promise for quicker, cheaper pharmaceutical research
Research from Linda Griffith’s laboratory group at MIT will be presented at SPIE Photonics West 2017.
The traditional path for most drugs is to start in a petri dish containing a single cell tissue culture, move to small animals such as rodents then on to primates, and finally on to clinical trials in humans. Along the path, every step could encounter results that deem the drug a failure and not suitable for the desired outcome.
Microsoft patents Holodeck-style projection room
The HoloLens field of view issue has been preoccupying Microsoft for some time, and they have been exploring a number of solutions, which tend to show up in their patent filings.
As Microsoft writes:
This discussion relates to complementary augmented reality. An augmented reality experience can include both real world and computer-generated content. For example, head-mounted displays (HMDs) (e.g., HMD devices), such as optically see-through (OST) augmented reality glasses (e.g., OST displays), are capable of overlaying computer-generated spatially-registered content onto a real world scene.
Biology’s ‘breadboard’
Nice; using gene regulatory protein from yeast as a method for reducing the work required for making cell-specific perturbations.
The human brain, the most complex object in the universe, has 86 billion neurons with trillions of yet-unmapped connections. Understanding how it generates behavior is a problem that has beguiled humankind for millennia, and is critical for developing effective therapies for the psychiatric disorders that incur heavy costs on individuals and on society. The roundworm C elegans, measuring a mere 1 millimeter, is a powerful model system for understanding how nervous systems produce behaviors. Unlike the human brain, it has only 302 neurons, and has completely mapped neural wiring of 6,000 connections, making it the closest thing to a computer circuit board in biology. Despite its relative simplicity, the roundworm exhibits behaviors ranging from simple reflexes to the more complex, such as searching for food when hungry, learning to avoid food that previously made it ill, and social behavior.
Understanding how this dramatically simpler nervous system works will give insights into how our vastly more complex brains function and is the subject of a paper published on December 26, 2016, in Nature Methods.
Quantum Computing Update: Coherent Electron-Photon Coupling Achieved, May Help Build Scalable Devices
Over 6 months ago we reported the electron-photon coupling discovery which makes scalable QC possibly. This article provides some additional content around the experiment.
The silicon-based device, created by researchers at Princeton University, could eventually help build viable and robust quantum computers.
