Quantum Computers are evolving for more than a decade and they are closer to reality. The field of quantum computing is too big to be described in one paper, but the real motivation for the quantum computers is its architecture. Firstly it is believed that classical computers can’t use the quantum algorithms and operations secondly the programs running on the quantum computers can’t run on traditional computer which is due to architecture and system. The quantum computer architecture is the key to build a quantum computer. The quantum computers are more complex than traditional computers. This research paper will discuss the quantum computer architecture.

Excerpt from the Book
III. HISTORY OF QUANTUM COMPUTING
The most sophisticated quantum computers till 2007 did not go beyond 16 QBITS, so a useful quantum computer is far away, but in recent years there is an improvement in quantum theory and quantum computing.
A single Qubit in each alanine molecules in liquid form having three nuclear spins is used by Alamos and MIT researchers in 1998.
Los Alamos National Laboratory scientists confirmed In 2000 March that they have developed a 7-qubit quantum computer having a single drop of liquid.
Shor’s algorithm was implemented on quantum computer by the scientists from IBM and Stanford University in 2001 and it is used to find the prime factors. A 7 QBIT QC is used to get the factors of 15, and the computer successfully calculated the factors.
In 2005 the scientists from QOQI institute (University of Innsbruck) confirmed that they successfully created first Qubyte by using ion traps.
A 12-qubit system was controlled by a group of scientists from University of Waterloo and Massachusetts in 2006. It is also learned that with the increase in Qubits the system becomes more complex.
Several pattern matching problems were solved by the quantum computer developed by the Canadian company D-Wave.
