The Kondo crossover in shot noise of a single quantum dot with orbital degeneracy
Kondo crossover orbital degeneracy
2010/11/19
We investigate out of equilibrium transport through an orbital Kondo system realized in a single quantum dot, described by the multiorbital impurity Anderson model. Shot noise and current are calculat...
Reduction of quantum noise in optical interferometers using squeezed light
Reduction quantum noise optical interferometers squeezed light
2010/11/8
We study the photon counting noise in optical interferometers used for gravitational wave detection. In order to reduce quantum noise a squeezed vacuum state is injected into the usually unused input ...
Efficient entanglement distribution for quantum communication against collective noise
Efficient entanglement distribution quantum communication against collective noise
2010/10/29
We present an efficient faithful entanglement distribution scheme for quantum communication against collective noise. Its setup is composed of polarizing beam splitters, half wave plates, polarization...
Quantum capacity under adversarial quantum noise: arbitrarily varying quantum channels
Quantum capacity adversarial quantum noise arbitrarily varying quantum channels
2010/10/29
We investigate entanglement transmission over an unknown channel in the presence of a third party (called the adversary), which is enabled to choose the channel from a given set of memoryless but non...
Do revivals of quantum correlations necessarily require quantum noise?
revivals quantum correlations necessarily quantum noise
2010/10/21
We show that in an N-partite system, where each subsystem is subject to a local completely
positive map, total correlations cannot, at later times, exceed their initial value. We then analyze the dyn...
Statistics and noise in a quantum measurement process
Statistics noise quantum measurement process
2010/10/18
The quantum measurement process by a single-electron transistor or a quantum point contact coupled to a quantum bit is studied. We find a unified description of the statistics of the monitored quantit...
