Entanglement of Gaussian states using beam splitter
Rabia Tahira, Manzoor Ikram, Hyunchul Nha +1
We study an experimental scheme to generate Gaussian two-mode entangled states via beam splitter. Specifically, we consider a nonclassical Gaussian state (squeezed state) and a the…
Hanbury Brown-Twiss effect and thermal light ghost imaging
Li-Gang Wang, Sajid Qamar, Shi-Yao Zhu +1
We show that the essential physics of the Hanbury Brown-Twiss (HBT) and the thermal light ghost imaging experiments is the same, i.e., due to the intensity fluctuations of the ther…
Quantum Zeno and Anti-Zeno Effect without Rotating Wave Approximation
H. Zheng, S. Y. Zhu
The effect of the anti-rotating terms on the short-time evolution and the quantum Zeno (QZE) and anti-Zeno (AQZE) effects is studied for a two-level system coupled to a bosonic env…
Uncertainty inequalities as entanglement criteria for negative partial-transpose states
Hyunchul Nha, M. Suhail Zubairy
In this Letter, we show that the fulfillment of uncertainty relations is a sufficient criterion for a quantum-mechanically permissible state. We specifically construct two pseudo-s…
Proposal for direct measurement of concurrence via visibility in a cavity QED system
Sang Min Lee, Se-Wan Ji, Hai-Woong Lee +1
An experimental scheme is proposed that allows direct measurement of the concurrence of a two-qubit cavity system. It is based on the cavity-QED technology using atoms as flying qu…
