Quantum Computing – Our Update

It is interesting to check out the future of technology. In an age of continuous innovation and development, when the discovery these days will lose its shine tomorrow, it is hard to identify innovations that will certainly change our future.

Engineering and technical developments are everyone’s concern, as they will certainly not be restricted to market, university class, and R&D laboratories. Instead, they will certainly make a remarkable distinction in our everyday lives. Here I will try to recognize some of the technologies that will transform our lives and our values in the coming years.

Photonic crystals are a quickly advancing technology first developed in the 1990’s. By engineering regular structures in an optical material, light will certainly react to the pattern as though it is passing through a crystal. Giving analysts far greater control over light, photonic crystals can be utilized to slow light to variable speeds at constantly shrinking costs with greater precision and less bulk. In truth, Professor Benjamin Eggleton’s research group has already shown a technique utilizing a photonic crystal structure crafted by a University of St. The Andrews team led by Professor Thomas F. Krauss for use over a broad bandwidth yields a sixteen fold boost in processing speeds over a traditional silicon chip, or 640 gigabits a second.

This Could Lead To Other Ideas

Unlike present PCs, quantum computers will have switches that can be in an on or off state at the same time. The system that will certainly make this possible is referred to as superposition, and the switches are referred to as quantum bits. The system will certainly make quantum computers run really quick. A fundamental quantum computer is likely to be functional by 2020.

Researchers are in the midst of creating a substance that can take a specific shape to carry out a certain job. The substance is known as Claytronics, and it consists of atoms. Individual atoms are programmed to move in three dimensions and position themselves so that they assume different shapes. This technology is most likely to have many applications varying from medical use to 3D physical renderings. It may take around two decades become a reality.

Techies are dealing with a job that would make our PCs able to include tens to hundreds of parallel working cores. The device will have the capability to process big amounts of information. To produce this technology, Intel is exploring the possibility of using nanotechnology and permitting billions of transistors.

Replay is one of the most advanced lifelike robotics ever produced. Reply, an android, is covered with a substance which is extremely similar to human skin. Sensing units put inside the robotic control its motions and enable it to respond to its environment. Remarkably, the robot can flutter its eyelids and duplicate breathing. fine runs finest in a static condition.

To further advance the computing world, techies have to create a hybrid CPU that is silicon based however includes organic parts also. The most appealing progress in details processing worries a microchip that places organic neurons onto a network of silicon or other materials. Future computers will be able to bridge the silicon and organic rounds to make use of processors that integrate both of these aspects.

The ‘spray-on’ nanocomputer would consist of particles that can be sprayed onto a patient. It would keep an eye on the client’s medical condition and communicate wirelessly with other machines.

Provider Ethernet is a business service/access technology. It can work as a transport method for both company and residential service. Ethernet will dominate the metro space in the future and will slowly displace SONET/SDH over the next 10 to 20 years.

Development sustains life. Techies can not manage to forget that technological improvement will certainly remain insufficient in the absence of contributions from all branches of knowledge and will not flourish if it does not benefit society.

Quantum Computing Uncovered

Quantum computers sound like a good idea that’s too good to be true. It sounds straight out of science fiction, a nerd’s dream, something akin to flying cars and cold fusion. There seems to be no way to actually build one of these magnificent devices.

The revolution of quantum physics may soon be about to pay off with the emergence of quantum computers, a term that has been bandied about for some years now. The promise of super fast computers, performing certain calculations billions of times quicker than any silicon-based computer and which that may even surpass the human brain in raw computing power, may not be too far away. Late last year another turning point in the race to prepare the first practical quantum computer was made when a team at the University of Bristol’s Centre for Quantum Photonics developed a microchip which manipulates and measures entanglement and mixture, two quantum phenomena which are essential principles in quantum computing.

The major potential applications of quantum computing are in cryptography and communications; however the potential for developing the first artificial intelligence is now within the reach of reality.

Hot Discussion: Quantum Computing

Quantum computing is, of course, a set of algorithms and processes that use quantum physics to process and store information. Unlike normal computing which only uses quantum mechanics just for hardware; quantum computers use it for everything from the CPU to memory to storage to programming. This quantum nature makes them the ultimate gaming machines. They would possess the power and responsiveness of a thousand or so super computers, but only necessary to take the form of your average smart phone. These computers would be so quickly that they would be in a position to run a real 24/7 holodeck, without any issues, in your basement. Physicists and mathematicians have been working on the algorithms for years, but there is still to be any advancement that would move quantum computing from theory to reality, until now that is.

moving on from that thought…

Recently, there has been much activity in the hunt for quantum computing that make me ponder the future. Here are five of such developments that may make science fiction become science fact.


Now that we’ve got a way to treat and store data quantumly, we require a way to read and write the data. We turn to the City College of New York and the University of California Berkeley where light was employed to encode information provided in the spins of atoms, for this. Combine this process with the salt transistors and nanotube memory and you’re a working quantum computer.

Now that we have our quantum computing processors, memory, and wires, we need a lattice to bring them all together. What better lattice to use than one specially made for them! Scientists at the University of California at Santa Barbara have discovered a way to grow computer parts through genetic modified bone cells. These cells can make anything we need from our nanotube wires to processing chips containing our salt, and growing them reduces the chances for error and other mishaps. We just have to be comfortable with having living computers on our desks.

So, there you have it. Everything seems to be filing in to place. All we need is for one enterprising individual to bring it all together. We now have everything we need to construct our first quantum computers. Let’s rejoice in the possibilities. You know I am.

Quantum Computing?

These machines use qubits rather than binary bits. A quantum computer makes use of principles of quantum mechanics, notably quantum interference in the most common design models, rather than conventional physics, with a view to operate. Just to illustrate the difference in processing between your home PC and something quantum, a 30-qubit system will run at the real world equivalent of a conventional unit running at 10 teraflops. Since home users have got access to processing in the gigaflop range at the time, it’s a huge jump in power. Maybe Crysis will finally run on Ultra.

It would appear that quantum computers are in reality, a reality. They are very hard to maintain, construct and understand. Unless you’re one of the geniuses who participate in the project, that is. Mostly theoretical at this stage, there have been major advances in the area of the quantum computing. In March 2000, scientists at the Los Alamos National Laboratory announced that they had constructed a 7-qubit quantum computer inside a drop a liquid. The liquid in question was either alanine (used to analyze quantum state decay) or the tongue busting trichloroethylene (used for quantum error correction) and the state of the qubits in issue is read by nuclear magnetic resonance or NMR. This is a method of indirectly measuring the state of a qubit.

The problem with measuring a qubit directly is that an accurate reading will drop a qubit out of superposition (should it be in that state) and turn your quantum computer into a conventional one.

The methods used in quantum computing, with a view to create results are much too lengthy to fully explain almost everywhere outside their scientific literature and the systems being created also vary, making a broad assessment impossible. Very much in their infancy, there are strides forward being made. From 2000 and Los Alamos’s 7-qubit machine there have been; another 7-qubit machine demonstrated by IBM and Stanford University; the preparation of the first qubit using ion traps in 2005 and most recently a 16-qubit quantum computer that was demonstrated by D-Wave Systems in late 2007. This computer was able to solve Sudoku puzzles and other problems that were demonstrated rather than just being a theoretical concept.

What About….

D-Wave Systems in particular are raring to have a working model of a quantum computer on the market as soon as possible. Their planned system won’t be a fully functional one but will rather be what one quantum algorithm designer calls ‘special purpose noisy piece of hardware’ that could take up the job of running physical simulations that are impossible on conventional silicon technology.

All won’t be roses when quantum computers finally hit the scene. First of all, they require a whole new kind of programming. If you were to program a quantum computer using the algorithms your current computer uses, it would act just like your current computer and process information the same way. But if you use algorithms designed to capitalize on the quantum computer’s full capabilities, amazing things start happening.

One of those amazing things is pattern recognition and lightning-fast calculation and processing. Scientists at AT&T Bell Labs devised an algorithm for factoring very large numbers. This problem is so difficult that it is the mathematics upon which modern encryption technology is based. Loaded on a computer such as the one you are on now, it would take about until such time as the universe has existed to break a typical encryption. But loaded onto a quantum computer, taking advantage of the ‘both’ nature of qubits, the encryption would be broken in seconds. This means that no digital data would ever be safe, because the infinite computing power to break any kind of encryption code would exist.

Looking forward toward the future of computing quantum computing has the potential to far outstrip anything that a home user could have imagined. Such processing power could even be put to use creating a true life simulation, a form of virtual reality indistinguishable from reality itself.
