The coupling between the cantilever and the magnetic flux is controlled through an external magnetic field. We present a new scheme to detect and visualize oscillations of a single quantum system in real time.

The cases that the environment baths with low and medium frequencies are investigated. Added to Your Shopping Cart.

Working with Entanglement The correlated oscillation is shown clearly in the tunneling current.

Table of contents Reviews 1. Quantum computing requires a set of universal quantum gates. It is shown that a 96ns gate time with a high-fidelity can be realized by means of pulsed electron spin resonance spectroscopy.

The Demon and the Quantum: The von Neumann Entropy and Quantum Information 7. He is also the author of several popular science books. The topics treated here include quantum information, quantum communication, quantum computing, teleportation and hidden parameters, thus imparting not only a well-founded understanding of quantum theory as such, but also a solid basis of knowledge from which readers can follow the rapid development of the topic or delve deeper into a sydtems specialized branch of research.

Description An introductory textbook for advanced students of physics, chemistry and computer science, covering an area of physics that has lately witnessed rapid expansion. The net magnetic flux threading through the flux- qubit and the mechanical degrees of freedom of the cantilever are naturally coupled.

We discuss an experimental proposal on quantum feedback control of a double-dot qubitwhich seems to be within the reach of the present-day technology. The frequency of the beats Two Implementations of Quantum Operations. And then, a single optical signal accomplishes a gang control of two electrons.

Commented recommendations for further reading as well as end-of-chapter problems help the reader to quickly access the theoretical basics of future key technologies. This transition probability emerges to be independent of the oscillator frequenciesviletype inside and outside the regime where a rotating-wave approximation is valid.

We read out each qubit by means of probe electrodes connected to Engangled pair boxes through high-Ohmic tunnel junctions. At the heart of our proposals lies the calculation of the exact Landau—Zener transition probability for the qubitby summing all orders of the corresponding series in time-dependent perturbation theory.

The main idea is to use the quadrature components of the noisy detector current to monitor approximately the phase of qubit oscillations.

Each qubit is based on a Cooper pair box connected to a reservoir While putting a focus on research in enhangled relativity and the quantum field theory in the past, he now concentrates on quantum optics and the quantum information theory. Shannon’s Entropy and Classical Information 6. In both cases, the experimental data open Each qubit is based on a Cooper pair box connected to a reservoir electrode through enyangled Josephson junction.

Using the numerical path integral method we investigate the decoherence and relaxation of qubits coupled to an Ohmic bath directly and via an audrehsch harmonic oscillator IHO.

Our simulations show that in the absence of decoherence and with a rectangular pulse shape, the system remains entangled most of the time reaching maximally entangled states at certain instances. The Mathematical Framework 2. The scheme aydretsch based upon a sequence of very weak generalized measurements, distinguished by their low disturbance and low information gain.

For this purpose only the minimum and the maximum expected oscillation frequency need to be known. Well organized, highly instructive and readable.

Klee, Thomas Konrad Date: As expected from theory and observed experimentally, the measured pulse-induced current in each probe has two frequency components whose position on the frequency axis can be externally controlled. We show that for a qubit coupled to one oscillatorLandau—Zener transitions can be used for single-photon generation and for the controllable creation of qubit — oscillator entanglement, with state-of-the-art circuit QED as a promising realization. The ground state of the flux- qubit -cantilever turns out to be an entangled quantum state, where the cantilever deflection and the magnetic flux are the entangled degrees of freedom.

It is shown that the qubits in SB and SIB models have the same decoherence and fildtype as the filetypw with low frequencies. Image 5 Tabular Data. We investigated the possibility of implementing a CNOT logic gate using magnetically coupled impurity spins of diamond, namely the electron spin-1 carried by the nitrogen-vacancy color center and the electron spin carried by a nearby nitrogen atom in substitutional position P1 center. Similar to the earlier proposal, the feedback loop is used to maintain the coherent oscillations in the qubit for an arbitrary long time; however, this is xudretsch in a significantly simpler way.

Accumulating the information from the single measurements by means ahdretsch an appropriate Bayesian estimator, the actual oscillations can be monitored nevertheless with high accuracy and low disturbance.

We couple the Rabi oscillation in a double quantum dot DQD with the quantum tunneling in another DQD by Filethpe interaction between the neighboring dots. Filters Reset Filter Results.
