Greenberger-Horne-Zeilinger Nonlocality in Arbitrary Even Dimensions
Jinhyoung Lee, Seung-Woo Lee, M. S. Kim
We generalize Greenberger-Horne-Zeilinger (GHZ) nonlocality to every even-dimensional and odd-partite system. For the purpose we employ concurrent observables that are incompatible…
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…
Quantum Secure Communication with W States
Jaewoo Joo, Jinhyoung Lee, Jingak Jang +1
A W state is pair-wisely entangled, belonging to the different class from Greenberger, Horne, and Zeilinger (GHZ) state. We show that the W state enables three variant protocols, t…
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…
Probabilistic nonlocal gate operation via imperfect entanglement
Jingak Jang, Jinhyoung Lee, M. S. Kim +1
Nonlocal gate operation is based on sharing an ancillary pair of qubits in perfect entanglement. When the ancillary pair are partially entangled, the efficiency of the gate operati…
