Complete security analysis of {quantum key distribution} based on unified model of sequential discrimination strategy
Min Namkung, Younghun Kwon
The quantum key distribution for multiparty is one of the essential subjects of study. Especially, without using entangled states, performing the quantum key distribution for multi…
Enhanced Optimal Quantum Communication by Generalized Phase Shift Keying Coherent Signal
Min Namkung, Jeong San Kim
It is well known that the maximal success probability of the binary quantum communication can be improved by using a sub-Poissonian non-standard coherent state as an information ca…
Indirect Measurement for Optimal Quantum Communication Enhanced by Binary Non-standard Coherent States
Min Namkung, Jeong San Kim
It is well known that the Helstrom bound can be improved by generalizing the form of a coherent state. Thus, designing a quantum measurement achieving the improved Helstrom bound i…
Revisiting Quantum discord for two-qubit X states: Error bound to Analytical formula
Min Namkung, Jinho Chang, Jaehee Shin +1
In this article, we investigate the error bound of quantum discord, obtained by the analytic formula of Ali et al.[Phys. Rev. A 81(2010), 042105] in case of general X states and by…
