Separable states to distribute entanglement
Jeonghoon Park, Soojoon Lee
It was shown that two distant particles can be entangled by sending a third particle never entangled with the other two [T. S. Cubitt et al., Phys. Rev. Lett. 91, 037902 (2003)]. I…
Constraint on teleportation over multipartite pure states
Jeong San Kim, Jaewoo Joo, Soojoon Lee
We first define a quantity exhibiting the usefulness of bipartite quantum states for teleportation, called the quantum teleportation capability, and then investigate its restricted…
Distribution and dynamics of entanglement in high-dimensional quantum systems using convex-roof extended negativity
Soojoon Lee, Jeong San Kim, Barry C. Sanders
We develop theories of entanglement distribution and of entanglement dynamics for qudit systems, which incorporate previous qubit formulations. Using convex-roof extended negativit…
Bound on distributed entanglement
Jeong San Kim, Soojoon Lee
Using the convex-roof extended negativity and the negativity of assistance as quantifications of bipartite entanglement, we consider the possible remotely-distributed entanglement.…
