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...
Security of quantum key distribution with state-dependent imperfections
quantum key distribution state-dependent imperfection security
2010/10/18
In practical quantum key distribution (QKD) system, the state prepara-tion and measurement are imperfect comparing with the ideal BB84 proto-col, which are always state-dependent in practical realizat...
Angular dependence and mode distribution of acoustic phonon emission by hot 2D electrons in GaAs/AlGaAs heterojunctions and quantum wells
2D electron gas transverse acoustic
