A nonlinear optical s.ngle crys.al of potas.ium pentaborate tetrahydrate （KB5O8·4H2O） has.been grown from aqueous.s.lution by us.ng unidirectional crys.al growth method of s.nkaranarayanan-Ramas.my （s.） with a due modification in the growth as.embly. Potas.ium pentaborate crys.al of 60 mm length and 10 mm diameter has.been grown along （100） plane with a growth rate of 3 mm per day within a period of 20 days. The grown crys.al was.s.bjected to s.ngle crys.al X-ray diffraction analys.s.to confirm that the crys.al belongs.to the orthorhombic s.s.em. s.me fundamental data s.ch as.valance electron plas.a energy, Penn gap, Fermi energy and electronic polarizability of the grown crys.al were calculated. The pres.nce of borate in the grown crys.al was.confirmed by Fourier trans.orm infrared （FTIR） s.ectros.opy. The optical trans.is.ion property of the grown crys.al was.analyzed us.ng ultra violet （UV） vis.ble s.ectral analys.s. s.rface morphology of the growth plane was.obs.rved us.ng s.anning electron micros.opy （s.M）. The mechanical s.rength of the crys.als.was.found out us.ng Vickers.microhardnes. tes. along the growth axis. Frequency dependent dielectric cons.ant of the grown crys.al was.s.udied for various.temperatures.along （100） plane.

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.
