device that can be thought as a gun. The second screen has a surface that can record or detect any wave or particle that manages to pass through the slits and strike the screen. As will be seen, sometime the researcher will open just one slit and other times both slits. The experiment is conducted in stages in order to contrast waves from particles. In the first stage a series of bullets (particles) will be fired toward the barrier with one slit open. As expected a vertical pattern of bullet

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

REFEREE REPORT MANUSCRIPT # SREP-16-20322 PAPER DESCRIPTION In the paper titled “The dynamical behaviors of complementary correlations under decoherence channels”, Du et.al have investigated the relationship between complementary correlations (CC) and the entanglement over noisy channels. In particular, for bipartite qubit systems, it has been shown that there exists an optimal threshold to which CC has to be compared in order to determine the dynamical behavior of entanglement. Furthermore, authors

Quantum Computing Less than 100 years ago, beginnings of the “new quantum theory” began. Only about 55 years after the new quantum theory began to emerge the idea that quantum phenomena can be used to perform computations. The idea being for a quantum computer was that classical computers would take an extremely long time to perform huge calculations, when a simple quantum system perform these same calculations all the time. One property that quantum computers have been observed to have was the

While periods of human thought are invariably brief, lasting only seconds at most, consciousness maintains a continuous flow, uninterrupted by any shift in thought. This is evident in the persistence of a unary self when conceptualized at a single moment in time and over a period of time. The agent responsible for synchronicity is the claustrum, located on the underside of the neocortex. Although the exact function of the claustrum remains to be verified, connectivity studies have shown that it plays

are intractable (w.r.t. resources). In order to tackle these problems, a super-Turing computational model has been devised and named as the quantum computer [1]. Quantum computation is based on the laws of quantum mechanics and can outperform classical computation in terms of complexity. The power comes from quantum parallelism that is achieved through quantum superposition [2] and entanglement [3]. Computability is unchanged so intractable problems are still unsolvable, but the exponential increase

Using a different setup than a standard linear optical system, [SOURCE]Choi et al. are able to use trapped ions as qubits in an optical quantum computer. As a direct result, unique possibilities for addressing scalability issues are discovered. Since trapped ions already have fundamentally low levels of coherent error, suppression of that error in a scaled quantum computer requires significantly less error correction. Also, the group demonstrates an architecture in which more than two entangled qubits

In the 21st, in our science classes, we are taught to believe that our world is actually made up of particles as the smallest constituents of matter. We are told that particles behave like waves because it makes no sense to teach that a particle moves faster than the speed of light, that particles can cause interference with one another, among other ridiculous things that we just never imagine a particle to do. What we are not told is that we never had to think about the smallest elements of matter

n the early 20th century it was discovered that particle such as the electron could be in two locations simultaneously . The behaviour of these particles is governed by quantum mechanics, a set of outlandish physical laws. Laws that allow these particles to be in an infinite number of states at a time, allowing them to be be in an infinite number of locations with an infinite range of characteristics simultaneously. However, can this observed behaviour be applied to actual people? It seems strange

fundamental and yet unintuitive concepts in quantum mechanics. Maximally entangled two-qubit states, often called Bell states, where shown to violate classical (local) correlation properties [33, 34] and are an essential building block for quantum communication and distributed quantum computation. Unfortunately, such entangled states are also difficult to generate and sustain as interaction with a noisy environment typically leads to rapid loss of their unique quantum properties. In the context of QSC, such
