摘要: We propose a scheme to generate three-quhit three-level singlet state in cavity QED, by placing three A-type SQUIDs single mode cavity. In this scheme, we make use of the interaction between and filed, classical pulses. The fields are vacuum during whole operation processes creating entanglement, there is no quantum information transformation fields. Because advantage SQUID-cavity system, quality factor greatly relaxed.
