TECHNOLOGY REVIEW: QUANTUM COMPUTERS
Recently, with the advancement in technology and up gradations in the digital computers, there has been a new term that has been into discussion which is the Quantum Computers. Quantum computers are those which make use of the quantum model for performing operations on the input data. It is a form of mechanical model. It helps in faster processing of the data and other operations as compare d to the digital computers.
Quantum computers utilises the power of molecules through super imposition of different states. It follows the system of qubits which may be representing value of zero, one or any other states and there is superposition of these states over each other in the form of two pairs or four pairs. It uses algorithms which would provide limited probability of the terms used.
Overview of technology
Quantum computing was thought to be a concept that would require years of research for development and application. Initially, it was in the planning phase, but now, it has transitioned to development and application phase with new technologies emerging across the globe to utilize its potential and boost the computing system. It is the solution of the need for high speed and fast processing computers that would be performing operations quicker than the current digital computers.
It would provide the users with a more secure technique of encryption where it outperforms the existing encryption techniques and tends to have better levels of confidentiality in handling the information and processing it.
Quantum computers has been a matter of discussion since the last decade and there are many researches currently being carried out on the development of such technology. The advantages of using quantum computers has been mentioned by many researchers and scholars. Few researchers have described the effectiveness of transmitting the information and processing it through quantum computers. It requires development of such quantum properties which can be used for processing and storing information in a faster way than the current digital computers (O’Brien, Ladd, Jelezko, & Laflamme, 2010).
Quantum computers provide protection from errors which would have developed due to unfavourable and uncontrollable surroundings. The recovery process is also very rapid as compared to other systems (Preskill, 1998). The speed of the quantum computers has been described and liked by many researchers. It can provide rapid speed and transform anything very quickly. This is due to the quantum algorithm model that it uses (Grover, 1998).
The quality of coherence in the operations of quantum computers has been evaluated and analysed by many researchers. They have stated the external and internal conditions that would help in the working of Quantum computers and the validity of its logic will be observed (Unruh, 1995). Few researchers have developed and evaluated the possibility of integrating the quantum computers and circuits in silicon (Tucker & Shen, 2000). The concept of the quantum computers is stated to be on the basis of reversible logic. There are many logical steps involved in its functioning (Reversible logic and quantum computers, 1985).
The qubits that are used in these reverse logic process serve to be the base for transferring of information and other such operations in Quantum computers. They are molecules and atoms with different frequencies that can use quantum physics model (TejadaJ & Hernandez, 2012). There are various strengths of using the above mentioned qubit method for quantum computing. They help in tremendously increasing the speed of processes and easy accessibility to information can be obtained (Bennett, Bernstein, & Brassard, 2006). There are limited researches and works developed on the application of quantum computers due to its complicated design and difficult working concept (Lloyd, 1993). The future of the quantum computers has been estimated to be very enlightening where they would be used very frequently. It involves a controlled behaviour on the quantum mechanics (Rabitz, Motzkus, & Kompa, 2000).
Application and benefits
There are various applications of quantum computers where it can be sued for the processing and storing of information which is currently done in digital computers. They can be used for developing the base for a super computer. Its application is being researched in different fields. It has the following benefits (Bennett, Bernstein, & Brassard, 2006):
• Easy to store large amount of information
• Can solve a complex problem very easily
• Provides fast computing recalling and storing of memory.
Potential security risks and security issues
The only threat that the Quantum Computer technology face is the maintaining the quantum mechanics model in different complex and typical situations. The difficult and complex design involved in its development serves to be the reason for limited application of Quantum Computers (Lloyd, 1993).
It supports the pillars of information security. It provides protection of the data through use of quantum algorithm model. It has easy and speedy detection of data. It prevents the information from being carried over by any unknown sources. These are the pillars of information security which are fulfilled by Quantum Computers.
There are five pillars of Information Assurance which are to be observed for its application in Quantum computers. It provides confidentiality of the information to be retained from any other means. It provides the integrity of the operations and functions. It has high levels of authentication identifying process and this would provide the required information assurance to the users.
It can be seen from various researches by technical scholars and scientists that quantum computers tends to solve the problems that are witnessed currently in using other systems. It requires a lot of extensive research and applicability in quantum computers to use them on a commercial scale and make it available to everyone. It is one of the most sought after emerging technology in the world which would provide solutions to high speed requirements of the people.
