| Summary: | A scheme is proposed to generate maximally entangled states of two <inline-formula> <math display="inline"> <semantics> <mi mathvariant="sans-serif">Λ</mi> </semantics> </math> </inline-formula>-type atoms trapped in separate overdamped optical cavities using quantum-jump-based feedback. This proposal can stabilize not only the singlet state, but also the other three triplet states by alternating the detuning parameter and relative phase of the classical fields. Meanwhile it is convenient to manipulate atoms, and much more robust against spontaneous emission of atoms. The parameters related to the potential experiment are analyzed comprehensively and it is confirmed that the quantum feedback technology is a significant tool for entanglement production with a high fidelity.
