Exponential sensitivity to dephasing of electrical conduction through a quantum dot
J. Tworzydlo, A. Tajic, H. Schomerus +2
According to random-matrix theory, interference effects in the conductance of a ballistic chaotic quantum dot should vanish when the dephasing time b…
Andreev billiards
C. W. J. Beenakker
This is a review of recent advances in our understanding of how Andreev reflection at a superconductor modifies the excitation spectrum of a quantum dot. The emphasis is on two-dim…
Coherent backscattering from a quantum dot is insensitive to the Ehrenfest time
A. Tajic, J. Tworzydlo, C. W. J. Beenakker
This paper was withdrawn by the authors. The purpose of this paper was to provide conclusive evidence for the Ehrenfest-time-independence of weak localization, by means of a comput…
Weak localization of the open kicked rotator
J. Tworzydlo, A. Tajic, C. W. J. Beenakker
We present a numerical calculation of the weak localization peak in the magnetoconductance for a stroboscopic model of a chaotic quantum dot. The magnitude of the peak is close to…
Transition from pure-state to mixed-state entanglement by random scattering
J. L. van Velsen, C. W. J. Beenakker
We calculate the effect of polarization-dependent scattering by disorder on the degree of polarization-entanglement of two beams of radiation. Multi-mode detection converts an init…
Charge detection enables free-electron quantum computation
C. W. J. Beenakker, D. P. DiVincenzo, C. Emary +1
It is known that a quantum computer operating on electron-spin qubits with single-electron Hamiltonians and assisted by single-spin measurements can be simulated efficiently on a c…
