Quantum dense coding via cavity decay
Zheng‐Yuan Xue, You-Min Yi, Zhuo‐Liang Cao · Journal of Modern Optics · 2006
We investigate a scheme for implementing quantum dense coding via cavity decay and linear optics devices. Our scheme combines two distinct advantages: the atomic qubit serves as a stationary bit and the photonic qubit as a flying bit, thus it is suitable for long distant quantum communication.
