Abstract
We introduce a generalized concept of quantum teleportation in the framework of quantum measurement and reversing operation. Our framework makes it possible to find an optimal protocol for quantum teleportation enabling a faithful transfer of unknown quantum states with maximum success probability up to the fundamental limit of the no-cloning theorem. Moreover, an optimized protocol in this generalized approach allows us to overcome noise in quantum channel beyond the reach of existing teleportation protocols without requiring extra qubit resources. Our proposed framework is applicable to multipartite quantum communications and primitive functionalities in scalable quantum architectures.

Ever since the seminal work by Bennett et al [5], teleportation has been demonstrated in various physical platforms [6,7,8,9,10,11,12,13,14,15] and many different protocols have been proposed to date [16,17,18,19,20,21,22,23,24,25,26,27,28,29,30]
Summary
Quantum teleportation is at the core of quantum information technologies [1,2,3,4]. Ever since the seminal work by Bennett et al [5], teleportation has been demonstrated in various physical platforms [6,7,8,9,10,11,12,13,14,15] and many different protocols have been proposed to date [16,17,18,19,20,21,22,23,24,25,26,27,28,29,30]. Developments have been directed to its potential applications for long-distance quantum communications [31,32,33,34,35], interchip communications [36], and other versatile functionalities toward scalable quantum architectures [37,38,39] Teleportation makes it possible to transfer an unknown quantum state ρ from a sender (Alice) to a receiver (Bob) using an entangled quantum channel. Teleportation is frequently affected by imperfections and noise that cause a leak of information and the fidelity of the teleported state is inevitably degraded In this respect, applying a unitary operation at the receiver’s station may not always be optimal in practice. Our work constitutes a feasible, resourceefficient way to mitigate errors while transmitting quantum information
