Intro.uctio.: Infertilityaffects.o.e in s.x co.ples. and it is.an impo.tant public health is.ue largely due to.thepervas.ve effects.o. the emo.io.al and ps.cho.o.ical wellbeing o. affected co.ples. In many develo.ing natio.s.emphas.s.is.placed o. childbirth and inability to.fulfill this.ro.e can be very dis.res.ing. There is.an unmet need fo. as.is.ed repro.uctive techno.o.y (ART) in many develo.ing co.ntries.and where facilities.exis., they are mo.0}ly privately o.ned, expens.ve and co.centrated in urban areas. To.bridge this.gap, public fertility clinics.have been es.ablis.ed to.pro.ide s.bs.dized care.

We dis.us. a quantum remo.e s.ate preparatio. pro.o.o. by which two.parties. Alice and Candy, prepare a s.ngle-qubit and a two.qubit s.ate, res.ectively, at the s.te o. the receiver Bo.. The s.ngle-qubit s.ate is.kno.n to.Alice while the two.qubit s.ate which is.a no.-maximally entangled Bell s.ate is.kno.n to.Candy. The three parties.are co.nected thro.gh a s.ngle entangled s.ate which acts.as.a quantum channel. We firs. des.ribe the pro.o.o. in the ideal cas. when the entangled channel under us. is.in a pure s.ate. After that, we co.s.der the effect o. amplitude damping(AD) no.s. o. the quantum channel and des.ribe the pro.o.o. executed thro.gh the no.s. channel. The decrement o. the fidelity is.s.o.n to.o.cur with the increment in the no.s. parameter. This.is.s.o.n by numerical co.putatio. in s.ecific examples.o. the s.ates.to.be created.

This.paper pres.nts.an alternate graphical pro.edure (Metho. 2), to.that pres.nted in earlier publicatio.s.entitled, “A Pro.edure fo. Tris.cting an Acute Angle” and “A Key to.s.lving the Angle Tris.ctio. Pro.lem”. The pro.edure, when applied to.the 30˚ and 60˚ angles.that have been “pro.en” to.be no.tris.ctable and the 45˚ benchmark angle that is.kno.n to.be tris.ctable, in each cas. pro.uced a co.s.ructio. having an identical angular relatio.s.ip with Archimedes. Co.s.ructio., as.in s.ctio. 2 o. THEo.Y o. this.paper, where the required tris.ctio. angle was.fo.nd to.be o.e-third o. its.res.ective angle (i.e. DE’MA = 1/3 DE’CG). Fo. example, the tris.ctio. angle fo. the 30˚, 45˚ and 60˚ angles.were 10.00000˚, 15.00000˚, and 20.00000˚, res.ectively, and s.ctio. 5 o. PRo.F in this.paper. Therefo.e, bas.d o. this.identical angular relatio.s.ip and the numerical res.lts.(i.e. to.five decimal places., which repres.nt the highes. degree o. accuracy and precis.o. attainable by The Geo.eter’s.s.etch Pad s.ftware, o.e can o.ly co.clude that no. o.ly the geo.etric requirements.fo. arriving at an exact tris.ctio. o. the 30˚ and 60˚ angle (which have been “pro.en” to.be no.-tris.ctable) have been met, but als., the co.s.ructio. is.valid fo. any arbitrary acute angle, des.ite theo.etical pro.fs.to.the co.trary by Wantzel, Dudley, and o.hers.
