A Review on Quantum Computers with Emphasize on Linear Optics Quantum Computing

Recently researchers have been explored quantum phenomena's for computation purpose and demonstrated important computational algorithms such as integer factorization using Shor's algorithm, unsorted date base search using Grover's algorithm, quantum cryptography, teleportation and many more. Many approaches have been investigated for implementing quantum algorithm physically. In this review quantum computer implementation techniques are introduced with an emphasize on linear optics quantum computing.
