摘要：
A scheme for controlled dense coding via cavity decay is proposed.In the scheme,two degenerate groundstates of six-level atoms are used as the storage qubits and the leaky photons act as flying qubits.The system isrobust against atomic spontaneous emissions and decoherence of cavity field.And the successful probability is nearly1 with quantum nondemolition parity detectors and photon detectors.The scheme may be realized based on currenttechnologies.
