A multi-sender-controlled quantum teleportation scheme is proposed to teleport several secret quan- tum states from different senders to a distance receiver based on only one Einstein-Podolsky-Rosen (EPR) pair with controlled-NOT (CNOT) gates. In the present scheme, several secret single-qubit quantum states are encoded into a multi-qubit entangled quantum state. Two communication modes, i.e., the detecting mode and the message mode, are employed so that the eavesdropping can be detected easily and the teleported message may be recovered efficiently. It has an advantage over teleporting several different quantum states for one scheme run with more efficiency than the previous quantum teleportation schemes. PACS numbers: 03.67.Dd, 03.65.Ud

We describe a novel multi-particle, multi-degree entangled system in which one particle is entangled to other particles in different degrees of freedom. It allows efficient teleportation of a higher dimensional quantum state. We give a new protocol for quantum key distribution using this state and describe possible experimental realizations of the proposed QKD as well as the teleportation protocols.

This paper proposes a novel quantum teleportation protocol leveraging multi-variable quantum entanglement. The core of the protocol relies on the strong correlations inherent in multi-dimensional entangled states to achieve high-efficiency and secure quantum teleportation. We demonstrate a framework for constructing such a protocol and analyze its potential advantages over traditional approaches. The key contribution lies in expanding the theoretical foundation of quantum teleportation, offering a new strategy for quantum communication and information processing. The protocol utilizes a series of Bell state measurements and classical communication to transfer the quantum state from one location to another, relying heavily on pre-shared multi-variable entangled pairs. We outline the mathematical formalism underpinning the protocol, including the description of the entangled states, the Bell state measurements, and the necessary classical information exchange. The protocol aims to enhance the transmission efficiency and bolster the security of quantum teleportation by exploiting the complexity and robustness afforded by multi-variable entanglement.
