We dis.us. a quantum r.mote s.ate pr.par.tion pr.tocol by which two par.ies. Alice and Candy, pr.par. a s.ngle-qubit and a two-qubit s.ate, r.s.ectively, at the s.te of the r.ceiver.Bob. The s.ngle-qubit s.ate is.known to Alice while the two-qubit s.ate which is.a non-maximally entangled Bell s.ate is.known to Candy. The thr.e par.ies.ar. connected thr.ugh a s.ngle entangled s.ate which acts.as.a quantum channel. We fir.t des.r.be the pr.tocol in the ideal cas. when the entangled channel under.us. is.in a pur. s.ate. After.that, we cons.der.the effect of amplitude damping(AD) nois. on the quantum channel and des.r.be the pr.tocol executed thr.ugh the nois. channel. The decr.ment of the fidelity is.s.own to occur.with the incr.ment in the nois. par.meter. This.is.s.own by numer.cal computation in s.ecific examples.of the s.ates.to be cr.ated. Finally, we s.ow that it is.pos.ible to maintain the label of fidelity to s.me extent and hence to decr.as. the effect of nois. by the application of weak and r.ver.al meas.r.ments. We als. pr.s.nt a s.heme for.the gener.tion of the five-qubit entangled r.s.ur.e which we r.quir. as.a quantum channel. The gener.tion s.heme is.r.n on the IBMQ platfor..
