Building "Skynet" quantum computing to build future cloud computing

Remember the omnipotent "Skynet" in Terminator? A new High-tech technology can be combined with the popular "cloud computing" on the web, making cloud computing more secure and faster, while simplifying http://www.aliyun.com/zixun/ Aggregation/13748.html "> infrastructure is a more efficient data center for cloud computing.

This High-tech technology is quantum computing--quantum computing is a new calculation based on quantum mechanics theory, different from the traditional binary calculation, it is by positioning the quantum, and then using the change of quantum information bits to encode information, processing speed far more than the traditional computer computing model, known as the potential of electronic computing unit.

Quantum overlap and the principle of association have produced tremendous computational power, a 2-bit register in a normal computer can store only one of the 4 binary digits (00, 01, 10, 11) at a time, while the 2-bit quantum bit (qubit) registers in a quantum computer can store these four numbers simultaneously. Because each qubit can represent two values. If there are more qubits, the computational power increases exponentially.

The concept of quantum computing was first developed by IBM's scientist R. Landauer and C. Bennett was presented in the 70 's. They mainly discuss the relationship between the computational process such as free energy, information (informations) and reversibility (reversibility).

At the same time, scientists report that quantum computing can be extended to "cloud" services-such as "Google services" will become faster and more secure. Olivier Pfist (Olivier Pfister), a professor of experimental atomic, molecular and optical physics at Virginia State University, says quantum algorithms can multiply computational speeds and are useful for database searching, identifying, solving complex arithmetic problems, and cracking cryptographic protocols. The data is encrypted by quantum, and the data cannot be read, let alone destroy the data. Only use a matching quantum cipher to open the data.

However, in order to realize quantum computing, there are some obstacles the first control question is how you can create a system with a large number of quantum information bits, control the quantum, and the second is to position the quantum, and how do you overcome the "scatter", which means that the quantum is constantly changing and how we should position it, To make quantum repeaters and quantum memory.

The first hurdle is clear: quantum systems are tiny. The challenge is to gain fine-grained control of the atomic level, controlling thousands of atoms. The removal is a more annoying problem. Philippe Stamp, director of the Pacific Institute of Theoretical Physics, physics and Astronomy at Columbia University, says that before we learn to control the dispersion, all the world's algorithms will not use quantum computers.

Through quantum encryption, the user can encrypt each qubit in the information and then send it to a remote data center, because there is a lot of encrypted information in the transmitted information, there will be countless random steps, in the completion of heavy calculation at the same time, to ensure the full security of cloud computing.

Switzerland has confirmed the feasibility of long-distance quantum ciphers in 2007 and has put them into use in its own network. Researchers at the University of Cork recently found that they can send quantum information in fiber to families around the world through broadband transmission. But the most important problem remains the establishment of quantum computers. In most cases, quantum computers exist only in limited laboratories and feel far away from our world.

D-wave, a Canadian quantum computing firm, officially released the world's first quantum computer, "D-wave one," in May 2011, although it can only handle some of the optimized tasks that are far from the traditional silicon processors in common tasks, But the quantum computer dream is a big step closer to us.

Scientists at the IBM Research department say they have made significant progress in quantum computing, and engineers are now ready to start developing fully functional quantum computers. This technological breakthrough allows scientists to reduce data error rates in initial calculations while maintaining the integrity of quantum mechanical properties in quantum bits (qubits).

The creation of a quantum computer means that the data processing capacity will be many times higher than the current conventional processor, says Mark Ketchen, physical information director at the IBM TJ Watson Research Center at the York Yorktown Heights, N.Y., USA. For example, the best multi-core processor today can encrypt or decrypt 150-bit passwords. However, if you want to decrypt a 1000-digit password, you need the world's computing resources to do it. Theoretically, however, it takes only a few hours to solve the problem on a quantum computer.

With the development of technology, the successful development of quantum computers will further simplify the infrastructure, lower the cost of infrastructure, and speed up the data center, and provide the impetus for the development of cloud computing. Remember Skynet in Terminator, maybe one day the global data center will reach that height with the help of quantum computing.
