Practical resources and measurements for lossy optical quantum metrology
Changhun Oh, Su-Yong Lee, Hyunchul Nha +1
We study the sensitivity of phase estimation in a lossy Mach-Zehnder interferometer (MZI) using two general, and practical, resources generated by a laser and a nonlinear optical m…

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…
