Quantum Dense Coding with Atomic Qubits

Physical Review Letters, 2004
We report the implementation of quantum dense coding on individual atomic qubits with the use of two trapped 9Be+ ions. The protocol is implemented with a complete Bell measurement that distinguishes the four operations used to encode two bits of classical information.

Orbital Angular Momentum Multiplexed Quantum Dense Coding

Physical Review Letters, 2021
To beat the channel capacity limit of conventional quantum dense coding (QDC) with fixed quantum resources, we experimentally implement the orbital angular momentum (OAM) multiplexed QDC (MQDC) in a continuous variable system based on a four-wave mixing process.

Dense Coding in Experimental Quantum Communication

Physical Review Letters, 1996
Classically, sending more than one bit of information requires manipulation of more than one two-state particle. We demonstrate experimentally that one can transmit one of three messages, i.e., 1 ``trit'' $\ensuremath{\approx}1.58\mathrm{bit}$, by manipulating only one of two entangled particles. The increased channel capacity is proven by transmitting

Relating quantum discord with the quantum dense coding capacity

Journal of Experimental and Theoretical Physics, 2014
We establish the relations between quantum discord and the quantum dense coding capacity in (n + 1)-particle quantum states. A necessary condition for the vanishing discord monogamy score is given. We also find that the loss of quantum dense coding capacity due to decoherence is bounded below by the sum of quantum discord.

Quantum private comparison based on quantum dense coding

Science China Information Sciences, 2016
A serious problem in cloud computing is privacy information protection. This study proposes a new private comparison protocol using Einstein-Podolsky-Rosen (EPR) pairs. This protocol allows two parties to secretly compare their classical information.

Quantum Dense Coding Without Joint Measurement

Communications in Theoretical Physics, 2009
We propose two schemes for quantum dense coding without Bell states measurement. One is deterministic, the other is probabilistic. In the deterministic scheme, the initial entangled state will be not destructed. In the probabilistic scheme, the initial unknown nonmaximal entangled state will be transformed into a maximal entangled one.
