In this paper, we introduce a novel controlled quantum communication protocol utilizing a quantum random walk involving one sender, one receiver, and multiple controllers. Inspired by classical random walk theory, quantum random walk serves as the foundation of our proposed protocol. With this protocol, we demonstrate the ability to transfer any n- dimensional quantum state to any party facilitated by any m number of controllers. Furthermore, any of the (m+1) individuals has the freedom to accept the role of the receiver. Rigorous testing of the protocol’s performance is conducted through quantum state tomography. We have run different variations of the circuits in IBMQ QASM simulator. Additionally, we explore the effectiveness of a weak measurement-based protocol designed to mitigate amplitude-damping noise’s detrimental effects on quantum states. By analyzing fidelity versus amplitude damping noise-strength plots for scenarios with and without the weak measurement protocol, we provide valuable insights into its protective capabilities across various levels of noise. These find- ings illuminate the protocol’s potential applications in quantum information processing

“…The seamless integration of these elements underscores the broad-reaching impact of quantum teleportation on diverse areas of quantum technology. Expanding on the landscape of point-to-point teleportation, numerous schemes have emerged, employing diverse entangled channels encompassing states such as Bell states [9][10][11], GHZ states [12][13][14], W states [15][16][17], cluster states [18][19][20] and hybrid states [21]. Simultaneously, the domain of experimental quantum teleportation has experienced rapid evolution, achieving realizations across a spectrum of physical systems.…”

The transmission of quantum states over extended distances is constrained by photon losses, rulingout direct amplification akin to classical telecommunications due to the non-cloning theorem. Overcomingthis challenge involves implementing quantum repeater protocols that leverage entanglement swapping tocreate long-distance entanglement from shorter distances. A novel multi-hop quantum teleportation scheme,blending concepts from quantum repeaters and teleportation, is under exploration. It aims to transferarbitrary two-qubit states between two distant parties, even in the absence of a direct quantum channel.Intermediate nodes, connected via a four-qubit entangled cluster state as quantum channels, are introducedbased on a more general routing protocol. Bell measurements are independently conducted by the sourcenode (Alice) and all intermediate nodes, with simultaneous transmission of measurement results, significantlyreducing time consumption. Determining the quantum state from Bell measurement results requires onlythe destination node (Bob) for a simple unitary transformation. Moreover, this protocol holds promise forimplementation on the IBM Quantum Experience platform once the requisite quantum circuits are designed.This overview encompasses both the theoretical and experimental status of the proposed scheme, withexperimental findings incorporated into quantum state tomography to verify the accuracy of the transmitted quantum state.

“…Bennett et al [6] proposed the first quantum teleportation protocol based on the Einstein-Podolsky-Rosen (EPR) pairs for teleporting an unknown photon state. Subsequently, many point-to-point teleportation schemes have been proposed, where various states are utilised as the entangled channels, such as Bell states [7][8][9], GHZ states [10][11][12], W states [13][14][15] and cluster states [16][17][18]. Meanwhile, experimental quantum teleportation has also been rapidly developed.…”

The combination of quantum communication technology and wireless networks brings a flexible and secure communication method that adapts to a more complex and open network environment. A new multi‐hop teleportation scheme is investigated for transferring arbitrary unknown multi‐qudit states between two distant parties. Based on a more general quantum routing protocol, intermediate nodes are introduced and linked with each other via d‐level entangled Greenberger‐Horne‐Zeilinger states as quantum channels. In this multi‐hop teleportation protocol, the source node and all the intermediate nodes can perform the entanglement measurement and transmit the measurement results simultaneously, thus reducing the time consumption largely. Furthermore, a general matrix formula is derived between the measurement results and the receiver's state, which enables the receiver to restore the unknown state efficiently. Compared with previous multi‐hop teleportation protocols, the teleportation protocol of arbitrary unknown multi‐qudit states of the authors can transfer more information, and it demonstrates lower computational complexity and higher flexibility.
