论文摘要
论文中介绍了基于空腔量子电动力学（QED）的大型有效载荷量子造影协议，该方案有效地使用了空腔QED中原子的进化定律。该协议构建了隐藏的通道以使用一个GHz状态与Hadamard操作一起在腔Q中的一个GHz状态和一个Bell状态之间交换纠缠邮件来传输秘密消息。量子隐志方案对腔衰减和热场不敏感。协议中详细分析了对窃听的能力，不可智能和安全性。事实证明，该协议不仅具有良好的不可识别性，而且还具有良好的安全性，可以防止窃听。此外，其隐藏通道的能力达到了五个位，比大多数以前的量子隐志方案大。
A large payload quantum steganography protocol based on cavity quantum electrodynamics (QED) is presented in the paper, which effectively uses the evolution law of atom in cavity QED. The protocol builds up hidden channel to transmit secret messages using entanglement swapping between one GHZ state and one Bell state in cavity QED together with the Hadamard operation. The quantum steganography protocol is insensitive to cavity decay and thermal field. The capacity, imperceptibility and security against eavesdropping are analyzed in detail in the protocol. It turns out that the protocol not only has good imperceptibility but also possesses good security against eavesdropping. In addition, its capacity of hidden channel achieves five bits, larger than most of those previous quantum steganography protocols.
