Entanglement in Mesoscopic Structures: Role of Projection
A. V. Lebedev, G. Blatter, C. W. J. Beenakker +1
We present a theoretical analysis of the appearance of entanglement in non-interacting mesoscopic structures. Our setup involves two oppositely polarized sources injecting electron…
Relation between entanglement measures and Bell inequalities for three qubits
C. Emary, C. W. J. Beenakker
For two qubits in a pure state there exists a one-to-one relation between the entanglement measure (the concurrence ) and the maximal violation of a Bell inequ…
Quantum-to-classical crossover of mesoscopic conductance fluctuations
J. Tworzydlo, A. Tajic, C. W. J. Beenakker
We calculate the system-size-over-wave-length () dependence of sample-to-sample conductance fluctuations, using the open kicked rotator to model chaotic scattering in a ballisti…
Dephasing of entangled electron-hole pairs in a degenerate electron gas
J. L. van Velsen, M. Kindermann, C. W. J. Beenakker
A tunnel barrier in a degenerate electron gas was recently discovered as a source of entangled electron-hole pairs. Here, we investigate the loss of entanglement by dephasing. We c…
Feedback of the electromagnetic environment on current and voltage fluctuations out of equilibrium
M. Kindermann, Yu. V. Nazarov, C. W. J. Beenakker
A theory is presented for low-frequency current and voltage correlators of a mesoscopic conductor embedded in a macroscopic electromagnetic environment. This Keldysh field theory e…
Quasiclassical fluctuations of the superconductor proximity gap in a chaotic system
M. C. Goorden, Ph. Jacquod, C. W. J. Beenakker
We calculate the sample-to-sample fluctuations in the excitation gap of a chaotic dynamical system coupled by a narrow lead to a superconductor. Quantum fluctuations on the order o…
