Security against the Invisible Photon Attack for the Quantum Key Distribution with Blind Polarization Bases
Won-Ho Kye, M. S. Kim
In this paper, we briefly show how the quantum key distribution with blind polarization bases [Kye et al., Phys. Rev. Lett. 95, 040501 (2005)] can be made secure against the invisi…
Completely-Positive Non-Markovian Decoherence
Jinhyoung Lee, Inbo Kim, Helen McAneney +2
We propose an effective Hamiltonian approach to investigate decoherence of a quantum system in a non-Markovian reservoir, naturally imposing the complete positivity on the reduced…
On the transfer of entanglement from a two-mode squeezed state to a pair of qubits
M. Paternostro, W. Son, M. S. Kim
There have recently been interests in transferring entanglement between two quantum systems in different Hilbert spaces. In particular, the study of entanglement transfer from a co…
Is quantum entanglement invariant in special relativity?
D. Ahn, H. J. Lee, S. W. Hwang +1
Quantum entanglements are of fundamental importance in quantum physics ranging from the quantum information processing to the physics of black hole. Here, we show that the quantum…
A scheme for direct observation of entanglement for Gaussian continuous variables
M. S. Kim, Jinhyoung Lee
We suggest an experimentally realizable scheme to test entanglement of a mixed Gaussian continuous variable state. We find that the entanglement condition is simplified for the fam…
Purification of entangled coherent states
H. Jeong, M. S. Kim
We suggest an entanglement purification scheme for mixed entangled coherent states using 50-50 beam splitters and photodetectors. This scheme is directly applicable for mixed entan…
