我们提出了一种控制产生纠缠单光子波包序列的腔qed方案。一个光子通过一个活跃的介质（比如原子）在一个腔内产生，并在腔外衰减成连续的辐射模式（比如耦合到光纤上）。以这种方式产生的后续波包表现为独立的逻辑量子位。这和产生最大纠缠的多量子位态的可能性在量子通信中提出了许多应用。
We propose a cavity-QED scheme for the controlled generation of sequences of entangled single-photon wavepackets. A photon is created inside a cavity via an active medium, such as an atom, and decays into the continuum of radiation modes outside the cavity(coupled, for example to an optical fiber). Subsequent wavepackets generated in this way behave as independent logical qubits. This and the possibility of producing maximally entangled multi-qubit states suggest many applications in quantum communication.
