Quantum Computing – things that need to be considered for our future Quantum Computing World

Posted by in categories: computing, finance, internet, mobile phones, quantum physics, robotics/AI, space, virtual reality, wearables

Sharing my recent posting that I did on Linkedin Pulse. I will admit that I purposely delayed this article in concerns of creating a panic; however, with the progress that has been occuring across the globe and in some cases accelerated the maturity of this technology; I believe it is time for governments, industries, etc. to start thinking about their own broader strategic plans around Quantum as well as how they will address any impacts.


Quantum Computing is making great progress in so many areas such as chips, network/ Internet, etc. each month. And, many industries such as financials, telecom, tech, and public sector namely defense and space, etc. have made big investments in this technology as well as have developed some interesting partnerships such as Wall Street. Everything looks so promising and exciting for our future when we look at the various ways how Quantum Computing can change our lives around AI, improving the medical technologies, how we interact with devices (wearables, VR, etc.), and even how we travel will advance through this technology. The future looks extremely rosy and bright; right?.

I believe it can be with Quantum; however, in every major shift/ disruption in technology, there is always a transformation progression that has to naturally occur thru stages. And, Quantum is no different; however, the disruption that Quantum will bring is going to be on a much more massive scale than what we have seen in the past. The reason why is Quantum is truly going to impact and improve every area of technology not just in devices, or a platform, AI, VR, etc.; I mean everything in technology will be changed and improved by Quantum over time.

Researchers gauge quantum properties of nanotubes, essential for next-gen electronics

Posted by in categories: computing, electronics, materials, nanotechnology, quantum physics

Loving the progress around Quantum.


Today, a group of scientists — John A. Rogers, Eric Seabron, Scott MacLaren and Xu Xie from the University of Illinois at Urbana-Champaign; Slava V. Rotkin from Lehigh University; and, William L. Wilson from Harvard University — are reporting on the discovery of an important method for measuring the properties of nanotube materials using a microwave probe. Their findings have been published in ACS Nano in an article called: “Scanning Probe Microwave Reflectivity of Aligned Single-Walled Carbon Nanotubes: Imaging of Electronic Structure and Quantum Behavior at the Nanoscale.”

The researchers studied single-walled carbon nanotubes. These are 1-dimensional, wire-like nanomaterials that have electronic properties that make them excellent candidates for next generation electronics technologies. In fact, the first prototype of a nanotube computer has already been built by researchers at Stanford University. The IBM T.J. Watson Research Center is currently developing nanotube transistors for commercial use.

Researchers discover new fundamental quantum mechanical property

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

Too cool.


Nanotechnologists at the University of Twente research institute MESA+ have discovered a new fundamental property of electrical currents in very small metal circuits. They show how electrons can spread out over the circuit like waves and cause interference effects at places where no electrical current is driven. The geometry of the circuit plays a key role in this so called nonlocal effect. The interference is a direct consequence of the quantum mechanical wave character of electrons and the specific geometry of the circuit. For designers of quantum computers, it is an effect to take account of. The results are published in the British journal Scientific Reports.

Interference is a common phenomenon in nature and occurs when one or more propagating waves interact coherently. Interference of sound, light or water waves is well known, but also the carriers of electrical current — electrons — can interfere. It shows that electrons need to be considered as waves as well, at least in nanoscale circuits at extremely low temperatures: a canonical example of the quantum mechanical wave-particle duality.

Science Documentary: DNA Hard Drives, Quantum Computing, Moore’s Law

Posted by in categories: computing, education, materials, nanotechnology, particle physics, quantum physics, science, security

DNA is similar to a hard drive or storage device, in that contains the memory of each cell of every living, and has the instructions on how to make that cell. DNA is four molecules combined in any order to make a chain of one larger molecule. And if you can read that chain of four molecules, then you have a sequence of characters, like a digital code. Over the years the price of sequencing a human genome has dropped significantly, much to the delight of scientists. And since DNA is a sequence of four letters, and if we can manipulate DNA, we could insert a message and use DNA as the storage device.

At this point in time, we are at the height of the information age. And computers have had an enormous impact on all of our lives. Any information is able to be represented as a collection of bits. And with Moore’s law, which states that computing power doubles every 18 months, our ability to manipulate and store these bits has continued to grow and grow. Moore’s law has been driven by scientists being able to make transistors and integrated circuits continuously smaller and smaller, but there eventually comes a point we reach in which these transistors and integrated circuits cannot be made any smaller than they already are, since some are already at the size of a single atom. This inevitably leads us into the quantum world. Quantum mechanics has rules which are, in many ways, hard for us to truly comprehend, yet are nevertheless tested. Quantum computing looks to make use of these strange rules of quantum physics, and process information in a totally different way. Quantum computing looks to replace the classical bits which are either a 0 or a 1, with quantum bits, or qubits, which can be both a 0 and a 1 at the same time. This ability to be two different things at the same time is referred to as a superposition. 200 qubits hold more bits of information than there are particles in the universe. A useful quantum computer will require thousands or even millions of physical qubits. Anything such as an atom can serve as a quantum bit for making a quantum computer, then you can use a superconducting circuit to build two artificial atoms. So at this point in time we have a few working quantum transistors, but scientists are working on developing the quantum integrated circuit. Quantum error correction is the biggest problem encountered in development of the quantum computer. Quantum computer science is a field that right now is in its very early stages, since scientists have yet been able to develop any quantum hardware.

The Secret to Everyday Time Travel Is Simple, Insane

Posted by in categories: particle physics, quantum physics, time travel

Since you first started learning about the world, you’ve known that cause leads to effect. Everything that’s ever happened to or near you has reiterated this point, making it seem like a fundamental law of nature. It isn’t.

It is, in fact, possible for an event to occur before its causal factors have manifested or happened. This isn’t how appliances work — you don’t have to worry about will have having left the oven on — but it is how particle physics works. It’s also the key to explaining how time travel, under the laws of quantum physics, could operate.

DARPA Backs Atoms-to-Products Milestone

Posted by in categories: engineering, materials, nanotechnology, particle physics, quantum physics

DARPA funds the Atoms-to-Products program that aims to maintain quantum nanoscale properties at the millimeter scale of microchips.

The main goal of the atoms-to-products program is to create technology and processes needed to create nanometer-scale pieces, with dimensions almost the size of atoms, into components and materials only millimeter scale in size. And to spur developments in the program DARPA has now posed the challenge to 10 laboratories across the nation.

To get the full benefits of nanoscale engineering at the millimeter scale, the organization has partnered with Intelligent Materials Solutions. “Our initial project will be to control infrared light by assembling nanoscale particles into finished components that are one million times larger,” explains Adam Gross, the team leader working closely with Christopher Roper to bring the Atoms-to Products project to fruition.

Wormholes are just quantum entangled black holes, says new research

Posted by in categories: cosmology, particle physics, quantum physics

Interesting, but older…


Two separate research groups, one of which is from MIT, have presented evidence that wormholes — tunnels that may allow us to travel through time and space — are “powered” by quantum entanglement. Furthermore, one of the research groups also postulates the reverse — that quantum entangled particles are connected by miniature wormholes.

A wormhole, or Einstein-Rosen bridge to give its formal name, is a hypothetical feature of spacetime that exists in four dimensions, and somehow connects to another wormhole that’s located elsewhere in both space and time. The theory, essentially, is that a wormhole is a tunnel that isn’t restricted by the normal limitations of 3D Cartesian space and the speed of light, allowing you to travel from one point in space and time, to another point in space and time — theoretically allowing you to traverse huge portions of the universe, and travel in time.

Researchers Have Succesfully Written Quantum Code On A Silicon Chip For The First Time

Posted by in categories: computing, quantum physics

Researchers from the University Of New South Wales(UNSW) in Australia have successfully demonstrated that they can write and control the quantum version of computer code on a silicon microchip. Computers, at the moment, use binary language to operate, 0 and 1. Together, these two bits generate code words that can be used to program complex commands. But in quantum computing language there’s also the option for bits to be in superposition, what this actually means is that they can be 1 and 0 at the very exact same time. This unlocks a massively more powerful programming language, but until now scientists haven’t been able to figure out how to write it.
