Mixed Entangled Coherent Channel:How useful is it for quantum teleportation?
Myungshik Kim, Hyunseok Jeong, J. Lee · Optical Fiber Communication Conference and International Conference on Quantum Information · 2001
We study an entangled coherent state within the framework of 2×2 dimensional Hilbert space and show that it can perfectly teleport some quantum information. We assess how useful it is when the entangled coherent state decoheres.
