Trends in Computer ArchitectureSince the presentation of the first computer, the search for computer computer architecture that is faster, smaller, and more efficient has been a constant goal of the computer industry. The first computers were large, heavy machines composed of thousands of senselessness electron tubes. The development of the transistor created the next evolution in computer architecture, the microchip. This is the architecture used in the current generation of computers. Like its vacuum tube predecessor, this architecture of utilizing transistors, squeeze out only go so far. Moores rectitude predicts that the number of components on a chip doubles every 18-24 months. At this rate each switch will eventually become the size of an atom. When this happens the laws of quantum mechanics must be used. A new evolution in computer architecture will need to be developed to share the rum laws of quantum mechanics. This architecture is already being developed and is call ed a quantum computer.Quantum computers extend in a rather distinctive way. Instead of using tralatitious bits, they use quantum bits, or qubits. These qubits are particles that can take on the unique states required for quantum computing. The best way to understand how a quantum computer work is by example. A basic example is to take a demo composed of 2 bits. Using a classic register, these two bits can have a lever of 0,1,2, or 3. Now using a quantum register with two qubits, the register can have a value of 0, 1, 2 and 3 all at ...
