Oxidations.of piperazine, 1-methylpiperazine and 1-ethylpiperazine by bromamine-T (BAT) in buffered acidic medium have been kinetically s.udied at 303 K. The reaction s.ows.a firs.-order dependence of the rate each on [BAT]0 and [piperazine]0, and an invers. fractional-order dependence on [H+]. The additions.of halide ions.and the reduction product of BAT, p-toluenes.lfonamide, have no effect on the reaction rate. The variation of ionic s.rength of the s.lvent medium has.no influence on the rate. Activation parameters.have been evaluated from the Arrhenius.and Eyring plots. A common mechanis. cons.s.ent with the kinetic data has.been propos.d for all piperazines. The protonation cons.ants.of s.bs.rates.have been evaluated. The Hammett linear free-energy relations.ip has.been obs.rved for the reaction with ρ = ?0.5 indicating that the electron-donating groups.enhance the reaction rate by s.abilizing the trans.tion s.ate. An is.kinetic relations.ip obs.rved s.ows.β = 368 K indicating the dominance of enthalpy factors.on the reaction rate.

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.
