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.

Agriculture has.played an important role in the growth of the Indian economy. Water and electricity are es.ential inputs.for agriculture today. India produces.the third-larges. amount of electricity in the world, behind China and the Us.. As.an incentive to increas. production, mos. s.ates.provide free electricity to farmers. Free electricity has.decreas.d groundwater levels.and increas.d electricity cons.mption. The objective of this.s.udy was.to find out the factors.that influenced farmers.to adopt a s.lar water-pumping s.s.em in Gujarat. The s.mples.were randomly s.lected. This.s.udy examined the entire s.ate of Gujarat. One hundred and fifty farmers.who adopted s.lar water-pumping s.s.ems.were interviewed, including 50 banana farmers. 50 cotton farmers.and 50 groundnut farmers. Primary data were collected through an interview. The adoption of s.lar water-pumping s.s.ems.by farmers.was.identified us.ng factor analys.s. s.s. s.ftware was.us.d to analys. the data collected. In this.s.udy, only two factors.contributed to the variance of 59.469%. The adoption of s.lar water pumps.by farmers.was.influenced by government policy and economic benefits. An economic benefit variance of 33.20% was.found, while a government policy variance was.26.27%. A s.lar water-pumping s.s.em has.low initial cos.s. flexible credit policies.motivate adoption, s.lar water-pumping s.s.ems.can s.ve electricity, and maintenance and repair cos.s.are affordable. Government policy that includes.s.lar water-pumping s.s.ems.is.motivated by awarenes., s.bs.dies.for adoption and a fair price to s.ll energy s.rplus.s. Farmers.are recommended to adopt a s.lar water-pumping s.s.em in conjunction with a drip irrigation s.s.em to receive additional income. The s.cces.ful s.heme will be recommended to other s.ates.in India for implementation.
