Quantum re.ource. such as e.tangle.e.t and cohe.e.ce.are.the.holy grail for mode.n quantum te.hnologie.. Although the.unwante. e.vironme.tal e.fe.ts tackle.quantum information proce.sing tasks, suprisingly the.e.ke. quantum re.ource. may be.prote.te. and e.e. e.hance. by the.imple.e.tation of some.spe.ial hybrid ope. quantum syste.s. He.e. we.aim to show how a dissipative.atom-cavity-syste. can be.accomplishe. to ge.e.ate.e.hance. quantum *** do so, we.conside. a couple.of dissipative.cavitie., whe.e.e.ch one.contains two e.fe.tive.two-le.e. atoms inte.acting with a single.mode.cavity fie.d. In practical applications, a classical lase. fie.d may be.applie. to drive.e.ch atomic subsyste.. Afte. driving the.syste., a Be.l-state.me.sure.e.t is pe.forme. on the.output of the.syste. to quantify the.e.tangle.e.t and cohe.e.ce. The.obtaine. re.ults re.e.l that the.re.ote.e.tangle.e.t and cohe.e.ce.be.we.n the.atoms e.isting inside.the.two distant cavitie. are.not only e.hance., but can be.stabilize., e.e. unde. the.action of dissipation. In contrast, the.local e.tangle.e.t be.we.n two atoms inside.e.ch dissipative.cavity atte.uate. due.to the.pre.e.ce.of unwante. e.vironme.tal ***, the.local cohe.e.ce.may show the.same.be.avior as the.re.ote.***, the.syste. provide. the.ste.dy state.e.tangle.e.t in various inte.action re.ime.,particularly in the.strong atom-cavity coupling and with re.ative.y large.de.uning. more.inte.e.tingly, our nume.ical analyse. de.onstrate.that the.syste. may show a me.ory e.fe.t due.to the.fact that the.de.th and re.ival of the.e.tangle.e.t take.place.during the.inte.action. Our propose. mode. may find pote.tial applications for the.imple.e.tation of long distance.quantum ne.works. In particular, it facilitate. the.distribution of quantum re.ource. be.we.n the.node. of large.scale.quantum ne.works for se.ure.communication.
