Einstein-Podolsky-Rosen Entanglement of Narrowband Photons from Cold Atoms
Jong-Chan Lee, Kwang-Kyoon Park, Tian-Ming Zhao +1
Einstein-Podolsky-Rosen (EPR) entanglement introduced in 1935 deals with two particles that are entangled in their positions and momenta. Here we report the first experimental demo…
Coherent and Dynamic Beam Splitting based on Light Storage in Cold Atoms
Kwang-Kyoon Park, Tian-Ming Zhao, Jong-Chan Lee +2
We demonstrate a coherent and dynamic beam splitter based on light storage in cold atoms. An input weak laser pulse is first stored in a cold atom ensemble via electromagnetically-…
Quantum discord protection from amplitude damping decoherence
Jiwon Yune, Kang-Hee Hong, Hyang-Tag Lim +6
Entanglement is known to be an essential resource for many quantum information processes. However, it is now known that some quantum features may be acheived with quantum discord,…
Scheme for directly observing the non-commutativity of the position and the momentum operators with interference
Jong-Chan Lee, Yong-Su Kim, Young-Sik Ra +2
Although non-commutativity of a certain set of quantum operators (e.g., creation/annihilation operators and Pauli spin operators) has been shown experimentally in recent years, the…
Experimental implementation of a fully controllable depolarizing quantum operation
Youn-Chang Jeong, Jong-Chan Lee, Yoon-Ho Kim
The depolarizing quantum operation plays an important role in studying the quantum noise effect and implementing general quantum operations. In this work, we report a scheme which…
Experimental demonstration of decoherence suppression via quantum measurement reversal
Jong-Chan Lee, Youn-Chang Jeong, Yong-Su Kim +1
Taming decoherence is essential in realizing quantum computation and quantum communication. Here we experimentally demonstrate that decoherence due to amplitude damping can be supp…
