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.

Metal nanowire networks.repres.nt a promis.ng candidate for the rapid fabrication of trans.arent electrodes.with high trans.is.ion and low s.eet-res.s.ance values.at very low depos.tion temperatures. A commonly encountered challenge in the formation of conductive nanowire electrodes.is.es.ablis.ing high-quality electronic contact between nanowires.to facilitate long-range current trans.ort through the network. A new s.s.em involving nanowire ligand removal and replacement with a s.miconducting s.l-gel tin oxide matrix has.enabled the fabrication of high-performance trans.arent electrodes.at dramatically reduced temperatures.with minimal need for pos.-depos.tion treatment.

In this.context, we applied the radial water jet drilling(RJD) technology to drill five horizontal holes.into a quarry wall of the Gildehaus.quarry clos. to Bad Bntheim, Germany. For tes.ing the s.ate-of-the-art jetting technology, a jetting experiment was.performed to inves.igate the influence of geological heterogeneity on the jetting performance and the hole geometry, the influence of nozzle geometry and jetting pres.ure on the rate of penetration, and the pos.ibility of localis.ng the jetting nozzle utilizing acous.ic activity. It is.obs.rved that the jetted holes.can inters.ct fractures.under varying angles. and the jetted holes.do not follow a s.raight path when jetting at ambient s.rface condition. Cuttings.from the jetting proces. retrieved from the holes.can be us.d to es.imate the res.rvoir rock permeability. Within the quarry, we did not obs.rve a change in the rate of penetration due to jetting pres.ure *** monitoring was.partially s.cces.ful in es.imating the nozzle location. Although the experiments.were performed at ambient s.rface conditions. the res.lts.can give recommendations.for a downhole application in deep wells.
