Abstract
The classical information capacity of dense coding through quantum channels was presented using the arbitrary mixed states of two qubits. The enhancement of encoding and transmission of classical bits of information were studied by shared entanglement between sender and receiver. The maximum classical channel capacity for states that are not maximally entangled was also discussed.
