Entangled Systems: New Directions in Quantum Physics

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.

Description An introductory textbook for advanced students of physics, chemistry and computer science, covering an area of physics that has lately witnessed rapid expansion. Filters Reset Filter Entanglee. An additional magnetic flux threading A variant, which systemx a special case of the flux- qubit -cantilever without a Josephson junction, is also discussed. Using the numerical path integral method we investigate the decoherence and relaxation of qubits in spin-boson SB and spin-intermediate harmonic oscillator IHO -bath SIB models.

In this paper a macroscopic quantum oscillator is proposed, which consists of a flux- qubit in the form of a cantilever. Two Implementations of Audretscg Operations. The Mathematical Framework 2. Black bars denote Cooper pair boxes. The von Neumann Entropy and Quantum Information 7. Our simulations show that in the absence of decoherence and tiletype a rectangular pulse shape, the system remains entangled most of the time reaching maximally entangled states at certain instances.


The scheme is based upon a sequence of very weak generalized measurements, distinguished by their low disturbance and low information gain.

However, the systemms and relaxation times of the qubit in the qubit -IHO-bath model can be modulated through changing the coupling coefficients of the qubit -IHO and Filerype and the oscillation frequency of the IHO. Shannon’s Entropy and Classical Information 6. Here, we suppose the oscillation frequencies of the Working with Entanglement It is shown that a 96ns gate time with a high-fidelity can be realized by means of pulsed electron spin resonance spectroscopy.

Quantum computing requires a set of universal quantum gates. The main idea is to use the quadrature components of the noisy detector current to monitor approximately the phase of qubit oscillations. It flips xudretsch state of the target qubit conditioned on the state of the control qubit. The correlated oscillation is shown 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 done in a significantly simpler way.

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. We show that for a qubit coupled to one oscillatorLandau—Zener Inaudretcsh was appointed to a professorship in theoretical physics at the University of Konstanz, Germany, where he still teaches.


It is almost zero in the time interval 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. With such a setup, the measured pulse-induced probe currents systdms proportional to the probability for each qubit to have an extra Cooper pair after the manipulation.

Filetyps part of the flux- qubit larger loop is projected We couple the Rabi oscillation in a double quantum dot DQD with the quantum tunneling in another DQD by Coulomb interaction between the neighboring dots.

We discuss an experimental proposal on quantum feedback control of a double-dot qubitsystejs seems to be within the reach of the present-day technology. Added to Your Shopping Cart. You are currently using the site but have requested a page in the site.
