Minimal control power of controlled dense coding and genuine tripartite entanglement
Changhun Oh, Hoyong Kim, Kabgyun Jeong +1
We investigate minimal control power (MCP) for controlled dense coding defined by the channel capacity. We obtain MCPs for extended three-qubit Greenberger-Horne-Zeilinger (GHZ) st…

Two different types of optical hybrid qubits for teleportation in a lossy environment
Hoyong Kim, Seung-Woo Lee, Hyunseok Jeong
We investigate the performance of quantum teleportation under a lossy environment using two different types of optical hybrid qubits. One is the hybrid of the vacuum and single-pho…

Transfer of different types of optical qubits over a lossy environment
Hoyong Kim, Jinwoo Park, Hyunseok Jeong
We compare three different types of optical qubits for information transfer via quantum teleportation and direction transmission under photon losses. The three types of qubits are…
