Chiral-mediated entanglement in an Aharonov-Bohm ring

Mostrar otras versiones (1)

We study the orbital entanglement in a biased Aharonov-Bohm ring connected in a four-terminal setup. We find that the concurrence achieves a maximum when the magnetic flux Φ B coincides with an integer number of a half flux quantum Φ 0/2. We show that this behavior is a consequence of the existence...

520 3 |a We study the orbital entanglement in a biased Aharonov-Bohm ring connected in a four-terminal setup. We find that the concurrence achieves a maximum when the magnetic flux Φ B coincides with an integer number of a half flux quantum Φ 0/2. We show that this behavior is a consequence of the existence of degenerate states of the ring having opposite chirality. We also analyze the behavior of the noise as a function of Φ and discuss the reliability of this quantity as evidence of entanglement. © 2012 American Physical Society.  |l eng
