摘要：
Despite the mathematical decisive argument on the seperability of mixed states in NMR at room temperature, NMR experiment has been extensively used for demonstrations of even non-local quantum algorithms. The corresponding inconsistency between the mathematical argument and the NMR quantum processing is studied and an experimental approach is proposed for detecting the existence of entanglement by implementing the superdense coding algorithm, whereas no pseudo-purification is used in this approach.
