Error Detection and Correction: An Introduction
In most communication system whether wired or wireless convolutional encoders are used and AWGN introduces errors during transmission. Various error correcting and controlling mechanisms are present. In this paper all mechanisms are studied and best mechanism on the basis of accuracy, complexity and power consumption is selected. There should be trade off between complexity of hardware and powe...
متن کاملAn Introduction to Quantum Error Correction
Quantum states are very delicate, so it is likely some sort of quantum error correction will be necessary to build reliable quantum computers. The theory of quantum error-correcting codes has some close ties to and some striking differences from the theory of classical error-correcting codes. Many quantum codes can be described in terms of the stabilizer of the codewords. The stabilizer is a fi...
متن کاملAn introduction to quantum error correction
Communication at high speeds, long distances, and in unknown environments often requires combatting noise that may affect or destroy data before it has reached its intended destination. When designing robust, practical communication systems, it is important to take such effects into account and engineer a system to be as immune to noise as possible. Classical communications often relies upon va...

with |α| + |β| = 1. The physical state of n particles is described by a vector in the Hilbert space H⊗n, which consists of all complex linear combinations of products |x1〉⊗|x2〉⊗· · ·⊗|xn〉, where |xi〉 ranges over the two basis vectors of the i-th copy of the Hilbert space H. Typically one uses the convention xi ∈ {0, 1} and the basis vectors of the 2-dimensional complex vector spaceH⊗n are writt...
