Performance of Entanglement-assisted Quantum LDPC Codes Constructed From Finite Geometries (2009)
Hsieh, Min-Hsiu, Yen, Wen-Tai, Hsu, Li-Yi
We investigate the performance of entanglement-assisted quantum low-density parity-check (LDPC) codes constructed from finite geometries. Though the entanglement-assisted formalism provides a...
Some quantum error correction codewords are undetermined by their parts (2008)
Yen, Wen-Tai, Hsu, Li-Yi, Hsieh, Min-Hsiu
We investigate the two-level, multi-partite quantum states with their non-injective reduced density matrices. As pointed out by Walck and Lyon, the undetermined states are stabilizer states \cite{4}....
Deterministic Dense Coding and Faithful Teleportation with Multipartite Graph States (2008)
Huang, Ching-Yu, Yu, I-Ching, Lin, Feng-Li, Hsu, Li-Yi
We proposed novel schemes to perform the deterministic dense coding and faithful teleportation with multipartite graph states. We also find the sufficient and necessary condition of a viable graph...
Entanglement detection via condition of quantum correlation (2007)
Li, Che-Ming, Hsu, Li-Yi, Chen, Yueh-Nan, Chuu, Der-San, Brandes, Tobias
We develop a novel necessary condition of quantum correlation. It is utilized to construct $d$-level bipartite Bell-type inequality which is strongly resistant to noise and requires only analyses of...
Correlation criteria for Bell type inequalities and entanglement detection (2006)
Li, Che-Ming, Hsu, Li-Yi, Lin, Wei-Yang, Chen, Yueh-Nan, Chuu, Der-San, Brandes, Tobias
We provide a novel criterion for identifying quantum correlation, which allows us to find connections between Bell type inequalities, entanglement detection, and correlation. We utilize the criterion...
Minimum-error discrimination between symmetric mixed quantum states (2003)
We provide a solution of finding optimal measurement strategy for distinguishing between symmetric mixed quantum states. It is assumed that the matrix elements of at least one of the symmetric...
Optimal Guessing Strategies in a Quantum Card Game (2002)
Three different quantum cards which are non-orthogonal quantum bits are sent to two different players, Alice and Bob, randomly. Alice receives one of the three cards, and Bob receives the remaining...
