We discuss.a quantum remote s.ate preparation protocol by which two parties, Alice and Candy, prepare a single-qubit and a two-qubit s.ate, respectively, at the site of the receiver Bob. The single-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 single entangled s.ate which acts.as.a quantum channel. We first describe the protocol in the ideal case when the entangled channel under use is in a pure s.ate. After that, we consider the effect of amplitude damping(AD) noise on the quantum channel and describe the protocol executed through the noisy channel. The decrement of the fidelity is shown to occur with the increment in the noise parameter. This is shown by numerical computation in specific examples of the s.ates to be created. Finally, we show that it is possible to maintain the label of fidelity to some extent and hence to decrease the effect of noise by the application of weak and reversal measurements. We also present a scheme for the generation of the five-qubit entangled resource which we require as.a quantum channel. The generation scheme is run on the IBMQ platform.

In this.article, we investigate the nonrelativistic quantum motion of a charged particle within a rotating frame, taking into account the Aharonov–Bohm(AB) effect and a uniform magnetic field. Our analysis entails the derivation of the equation of motion and the corresponding radial equation to describe the system. solving the resulting radial equation enables us to determine the eigenvalues.and eigenfunctions, providing a clear expression for the energy levels. Furthermore,our numerical analysis highlights the subs.antial influence of rotation on both energy levels.and optical properties. specifically, we evaluate the photoionization cross-section with and without the effects of rotation. To elucidate the impact of rotation on the photoionization process of the system, we present graphics that offer an appealing vis.alization of the intrinsic nature of the physics involved.
