Quantum Neural Network

1.1 Introduction and Background

The eld of articial 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 specic problems.

The network can be trained to do various tasks like pattern recognition,

data classication,function approximation etc. ANNs are widely used in the

elds of computer vision and speech recognition.

1.1.1 Architecture of an Articial Neural Network

1.1.2 Backpropagation

Learning is the way we acquire knowledge about the world around us, and it

is through this process of knowledge acquisition, that the environment alters

our behavioural responses. Similarly, in articial neural networks, learning

rules are used, to modify the behaviour of the network in response to the

external stimuli (inputs).

For multilayered feedforward networks, a commonly used algorithm for

weight adjustment is the backpropagation algorithm. There is some math

involved in the derivation of the formula which can be referred to from [4].

The nal form of the formula looks like:

wij = jyi

Where,

wij is the weight between the neurons i; j

j is the local gradient of the jth neuron

and, yi is the output of the ithneuron

1.3.3 Training and Performance

The training of the network can be carried out using the backpropagation

algorithm. Because of the unavailability of quantum hardware, the network

cannot be tested but we can simulate the network on a classical computer.

1.4 Summary and Discussion

Provide a summary and discuss what you have understood. summarize the

main points and also mention if have found some subtopics dicult.

## Physics Of Physics : Quantum Theory Essay examples

- Quantum theory explains the world of physics that attempts to understand the nature and behavior of matter and energy at a subatomic level (Rouse, Margaret). Its applications can be found in objects used in everyday life, such as lasers, CDs, DVDs, digital cameras, photocopiers, and more. An atom is an object containing positive and negative charged particles with more than 99.9% of its mass, produced from the protons and neutrons, packed into a small nucleus. This nucleus, located in the center of the atom, is orbited by electrons, point particles that are even smaller in size.... [tags: Quantum mechanics, Electron, Photon, Light]

## Quantum Physics : Quantum Mechanics Essay

- In the world of subatomic particles, the rules that normally apply to objects that are visible by the human eye are totally disregarded. Subatomic particles behavior can be attempted to be explained by a term called quantum mechanics. Quantum mechanics gives the probability of where a particle will be located at, such as point A or point B. It describes atoms or particles, really anything at that level or smaller in a similar way in which relativity describes the laws of how much larger objects behave....

## Quantum Physics Essay examples

- Quantum mechanics is the study of the behavior of energy and matter at the atomic, molecular and nuclear levels and sometimes even microscopic levels. The first initial information on quantum mechanics was first discovered in the early 20th century by a pioneering scientist Max Planck, because of this early knowledge of quantum energy it led to the first invention of the transistor. Scientist Max Planck discovered an equation that explained the results of these tests. The equation is as follows, E=Nhf, with E=energy, N=integer, h=constant, f=frequency....

## Quantum Computers Essay

- introduction A quantum computer is one which exploits quantum-mechanical interactions in order to function; this behavior, found in nature, possesses incredible potential to manipulate data in ways unattainable by machines today. The harnessing and organization of this power, however, poses no small difficulty to those who quest after it. Subsequently, the concept of quantum computing, birthed in the early 80's by physicist Richard Feynman, has existed largely in the realm of theory. Miraculous algorithms which potentially would take a billionth of the time required for classical computers to perform certain mathematical feats, and are implementable only on quantum computers, as such ha...

## Quantum Computers Essay

- Missing figures With today's technology we are able to squeeze millions of micron wide logic gates and wires onto the surface of silicon chips. It is only a matter of time until we come to a point at which the gates themselves will be made up of a mere handful of atoms. At this scale, matter obeys the rules of quantum mechanics. If computers are to become smaller and more powerful in the future, quantum technology must replace or reinforce what we have today. Quantum computers aren't limited by the binary nature of the classical physical world.... [tags: quantum physics computer]
