DETERMINISTIC QUANTUM DENSE CODING WITH A GENUINE MULTIPARTITE ENTANGLEMENT IN LINEAR OPTICAL SYSTEM
Yi Wang, Liu Ye, Qing-Min Song, Bao‐Long Fang · International Journal of Quantum Information · 2011
We propose two schemes for realizing dense coding in linear optical system. These schemes are based on a genuine four-qubit entangled state |Ψ〉 as a shared resource of entanglement. There are many interesting properties and possible applications in quantum information processing and fundamental tests of quantum physics by this state. By distinguishing Alice's operation we can easily achieve the dense-coding.
