    In this work, we apply a two-dimensional correlation spectroscopy technique which employs double-quantum-coherence to investigate many-body effects in a semiconductor quantum well. The signal is detected along the direction k 1 + k 2 − k 3, where k 1, k 2 and k 3 are the pulse wave vectors in chronological : Lijun Yang, Shaul Mukamel.

      The processing of quantum information based on the electron spin degree of freedom1,2 requires fast and coherent manipulation of local spins. One approach is to provide spatially selective tuning. Quantum Coherence Correlation and Decoherence in Semiconductor Nanostructures Toshihide Takagahara Limited preview - Frontiers of Nano-Optoelectronic Systems.

    Decoherence is there a key issue since electrical circuits are more prone to decoherence than microscopic objects such as atoms. We introduce the different families of solid state qubits, which are either based on single particle states in semiconductor nanostructures, or on global quantum states of superconducting Josephson by: 1. A. Models of einselection 1. Decoherence of a single qubit 2. The classical domain and quantum halo 3. Einselection and controlled shifts B. Einselection as the selective loss of information 1. Conditional state, entropy, and purity 2. Mutual information and discord C. Decoherence, entanglement, dephasing, and noise

Quantum Coherence Correlation and Decoherence in Semiconductor NanostructuresPages Chapter 5 - Higher-order Coulomb correlation effects in semiconductorsAuthor: S.R. Bolton. Spatial coherence. In some systems, such as water waves or optics, wave-like states can extend over one or two dimensions.

Spatial coherence describes the ability for two points in space, x 1 and x 2, in the extent of a wave to interfere, when averaged over precisely, the spatial coherence is the cross-correlation between two points in a wave for all times. Coherence, Correlation, and Control in Nanostructures Conventional electronic devices typically rely only on charge transport.

However, in small semiconductor structures of order nanometers in size (quantum dots), fully quantum mechanical properties such as quantum phase and spin can become important.

$\begingroup$ @XinWang Yes, the notion of decoherence means that the coherence is destroyed. Here coherence is quite associated to the notion that you mention, a constant phase difference between two things. In quantum mechanics we say that we have a coherent superposition of two states, $\psi_1$ and $\psi_2$ when the global state is $\Psi = A(\psi_1 +.

als. Quantum interference becomes more important as the dimensionality of the conductor is reduced. Quasi-one dimensionality can readily be achieved in a 2DEG by lateral confinement.

Semiconductor nanostructures are unique in offering the possibility of studying quantum transport in an arti-ficial potential landscape. This is the regime of. This book presents the physics of semiconductor nanostructures with emphasis on their electronic transport properties.

At its heart are five Author: Thomas Ihn. In which sense quantum decoherence is the "loss" of quantum coherence.

Why are these two concepts so important in quantum mechanics, computation, and information. It may also be helpful to mention concrete examples of situations where these concepts come into play in these three fields.

If I understood correctly, quantum decoherence is a. in decoherence relate decoherence in the system to noise and fluctuations in the environment. Applying the consistent history scheme to correlations of histories, we formulated a new way to describe decoherence and quantum to classical transition for a closed system, where the coarse-grainingis determined by the by: 5.

Abstract. The prospect of developing magnetic qubits is discussed. The first part of the article makes suggestions on how to achieve the coherent quantum superposition of spin states in small ferromagnetic clusters, weakly uncompensated antiferromagnetic clusters, and Author: Eugene M.

Toshihide Takagahara, Quantum Coherence Correlation and Decoherence in Semiconductor Nanostructures, page The significant Q-spoiling observed is in part due to the refractive loss in the contact area between the QW sample and the sphere since the QW sample has an index of refraction greater than that of the fused silica microsphere.This textbook describes the physics of semiconductor nanostructures with emphasis on their electronic transport properties.

At its heart are five fundamental transport phenomena: quantized conductance, tunnelling transport, the Aharonov-Bohm effect, the quantum Hall effect, and the Coulomb blockade effect.Decoherence is the term used to describe the destruction of phase relations in the state of a quantum mechanical system, as a result of a dynamical process.

According to the Superposition Principle, any two state vectors in a Hilbert space of a quantum mechanical system, can be linearly added together to form.
