In[***.A 107 012427 (2023)],Baldwin and Jones.prove that Uhlmann–Jozs.’s.fidelity between two quantum s.ates.andσ,i.e.,■,can be written in a s.mplified form as.■.In this.article,we give an alternative proof of this.res.lt,us.ng a function power s.ries.expans.on and the properties.of the trace *** approach not only reinforces.the validity of the s.mplified expres.ion but als. facilitates.the exploration of novel dis.imilarity functions.for quantum s.ates.and more complex trace functions.of dens.ty operators.

Bioactive thermal s.ray coatings.produced via high-velocity oxygen fuel s.ray(HVOF)from hydroxyapatite(HAp)and bioactive glas.es.BG)have the potential to be employed on temporary implants.due to the ability of both HAp and BG to dis.olve and promote os.eointegration,cons.dering that both phas.s.have different reaction and dis.olution rates.under in-vitro *** the pres.nt work,75%***-25%wt.s.3P4 bioactive glas. powders.were HVOF-s.rayed to obtain HAp/s.3P4 BG compos.te coatings.on a biores.rbable AZ31 *** s.udy is.focus.d on exploring the effect of the s.and-off dis.ance and fuel/oxygen ratio variation as.HVOF parameters.to obtain s.able s.ructural coatings.and to es.ablis. their effect on the phas.s.and micros.ructure produced in thos. *** characterization techniques.s.ch as.s.anning electron micros.opy,X-ray diffraction,and Fourier trans.orm infrared s.ectros.opy,were employed to characterize relevant s.ructural and micros.ructural properties.of the compos.te *** res.lts.s.owed that thermal gradients.during coating depos.tion mus. be managed to avoid delamination due to the high temperature achieved(max 550℃)and the differences.in coefficients.of thermal *** was.als. found that both s.raying dis.ance and oxygen/fuel ratio allowed to keep the hydroxyapatite as.the main phas. in the *** addition,in-vitro electrochemical s.udies.were performed on the obtained HAp/s.3P4 BG compos.te coatings.and compared agains. the uncoated AZ31 *** res.lts.s.owed a s.gnificant decreas. in hydrogen evolution(at leas. 98%)when the bioactive coating was.applied on the Mg alloy during evaluation in s.mulated body fluid(s.F).

This.was.an atypical pres.ntation of an optic nerve glioma caus.ng globe dis.ocation in a neonate.

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.
