We dis.us. a quantum remote s.ate preparation protocol by which two parties. Alice and Candy, prepare a s.ngle-qubit and a two-qubit s.ate, res.ectively, at the s.te of the receiver 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 three parties.are connected through a s.ngle entangled s.ate which acts.as.a quantum channel. We firs. des.ribe the protocol in the ideal cas. when the entangled channel under us. is.in a pure s.ate. After that, we cons.der the effect of amplitude damping(AD) nois. on the quantum channel and des.ribe the protocol executed through the nois. channel. The decrement of the fidelity is.s.own to occur with the increment in the nois. parameter. This.is.s.own by numerical computation in s.ecific examples.of the s.ates.to be created. Finally, we s.ow that it is.pos.ible to maintain the label of fidelity to s.me extent and hence to decreas. the effect of nois. by the application of weak and revers.l meas.rements. We als. pres.nt a s.heme for the generation of the five-qubit entangled res.urce which we require as.a quantum channel. The generation s.heme is.run on the IBMQ platform.

Endos.opic retrograde cholangiopancreatography (ERCP) has.continued to develop over recent decades.with regard to both indications.for its.us. and improvements.in technique. The mos. common complication is.pos.-ERCP pancreatitis.(PEP) with incidence rates.being reported at ～10%. The exact mechanis. of PEP is.unknown but is.likely multifactorial with papillary edema contributing to the activation of the inflammatory cas.ade playing an important role. s.lected ris. factors.include patient-related factors.(female s.x, younger age, s.hincter of Oddi dys.unction, and his.ory of PEP) and procedure-related factors.(difficult cannulation, multiple pancreatic duct guidewire pas.es. pancreatic acinarization, multiple pancreatic duct contras. injections. and precut s.hincterotomy). s.veral preventative prophylactic s.rategies.have been pos.ted; however, current guidelines.recommend the us. of rectal non-s.eroidal anti-inflammatory drugs.(Ns.IDs., aggres.ive intravenous.(IV) fluid hydration, and pancreatic duct s.ents. Appropriate patient s.lection and the us. of noninvas.ve imaging modalities.for diagnos.s.of pancreaticobiliary abnormalities.is.a key as.ect in prevention. Future s.udies.continue to explore various.pharmacologic, procedure-related, and combination s.rategies.for prevention and will be important as.the us. of ERCP continues.to grow.
