Chapter 1 Quantum Neural Network 1.1 Introduction and Background The eld of articial neural networks (ANNs) draws its inspiration from the working of human brain and the way brain processes information. An ANN is a directed graph with highly interconnected nodes called neurons.Each edge of the graph has a weight associated with it to model the synaptic eciency. The training process involves updating the weights of the network in such a way that the network learns to solve the problem. The neurons in the network work together to solve specic problems. The network can be trained to do various tasks like pattern recognition, data classication,function approximation etc. ANNs are widely used in the elds of computer vision†¦show more content†¦This has been demonstrated by many quantum 1.2. QUANTUM MECHANICS AND ANN 3 Figure 1.2: Quantum analogies for dierent concepts of articial neural networks algorithms such as Grovers search algorithm, Shors factorisation algorithm etc. We can use this property and our knowledge of classical neural net- works to create a new computing paradigm called quantum neural networks (QNNs). There are many ways of using building a QNN. Figure 1.2 has been taken from [2], which shows various approaches to achieving For the purpose of this chapter will will consider only the Menneer and Narayanan model. This model is based on the parallel universe interpreta- tion of Quantum mechanics. 1.2.1 The parallel universe interpretation The parallel universe interpretation or the many world interpretation of quantum mechanics was proposed by Hugh Everett in the year 1957 [3]. 4 CHAPTER 1. QUANTUM NEURAL NETWORK It says that there exists an innite number of coexisting universes and each possible outcome of an event occurs in a parallel universe. According to the theory superposition states of a wavefunction lies in dierent universes and the quantum system interacts with itself in dierent universes. Any act of measurement sees the state only in one universe. This interpretation can help in better understanding of the eld of quan- tum information. 1.3 Quantum Neural Network We will try toShow MoreRelatedEssay On Better Glass Edu867 Words   |  4 PagesThere are several projects for this research opportunity. I am part of a project called Better Glass Edu, a project specifically for the first year researchers to get acclimated to the terms of and usage of a neural network using machine learning algorithms.

In the 40s and 50s, a number of researchers explored the connection between neurology, information theory, and cybernetics. Some of them built machines that used electronic networks to exhibit rudimentary intelligence, such as W. Grey Walters turtles and the Johns Hopkins Beast. Many of these researchers gathered for meetings of the Teleological Society at Princeton and the Ratio Club in England.
