ENTANGLEMENT AND superdense coding WITH LINEAR OPTICS
收藏 引用
INTERNATIONAL JOURNAL OF QUANTUM INFORMATION 2011年 第7-8期9卷 1737-1744页
作者: Pavicic, Mladen Univ Zagreb Fac Civil Engn Chair Phys Zagreb 41000 Croatia
We discuss a scheme for a full superdense coding of entangled photon states employing only linear optics elements. By using the mixed basis consisting of four states that are unambiguously distinguishable by a standar... 详细信息

Quantum information processing through a genuine five-qubit entangled state in cavity QED
收藏 引用
QUANTUM INFORMATION PROCESSING 2010年 第5期9卷 643-662页
作者: Qiu, Liang China Univ Min & Technol Dept Phys Xuzhou 221116 Peoples R China
The utility of a five-qubit entangled state for quantum teleportation, quantum state sharing and superdense coding is investigated. The state can be utilized for perfect teleportation and quantum state sharing of an a... 详细信息

Near-Capacity Code Design for Entanglement-Assisted Classical Communication over Quantum Depolarizing Channels
收藏 引用
IEEE TRANSACTIONS ON COMMUNICATIONS 2013年 第12期61卷 4801-4807页
作者: Babar, Zunaira Ng, Soon Xin Hanzo, Lajos Univ Southampton Sch Elect & Comp Sci Commun Signal Proc & Control Grp Southampton SO17 1BJ Hants England Univ Southampton Sch Elect & Comp Sci Southampton SO17 1BJ Hants England
We have conceived a near-capacity code design for entanglement-assisted classical communication over the quantum depolarizing channel. The proposed system relies on efficient near-capacity classical code designs for a... 详细信息

Limits on the ability of quantum states to convey classical messages
收藏 引用
JOURNAL OF THE ACM 2006年 第1期53卷 184-206页
作者: Nayak, A Salzman, J Univ Waterloo Dept Combinator & Optimizat Waterloo ON N2L 3G1 Canada Perimeter Inst Theoret Phys Waterloo ON Canada Stanford Univ Dept Stat Stanford CA 94305 USA
We revisit the problem of conveying classical messages by transmitting quantum states, and derive new, optimal bounds on the number of quantum bits required for this task. Much of the previous work on this problem, an... 详细信息
