Quantum manipulation in a Josephson LED
arXiv:0911.5100 · doi:10.1088/0957-4484/21/27/274004
Abstract
We access the suitability of the recently proposed Josephson LED for quantum manipulation purposes. We show that the device can both be used for on-demand production of entangled photon pairs and operated as a two-qubit gate. Besides, one can entangle particle spin with photon polarization and/or measure the spin by measuring the polarization.
