Quantum key distribution by teleportation and unextendible product operator bases

Abstract

Quantum teleportation and quantum key distribution (QKD) both play a key role in the application of quantum information processing. They have been widely realized in experiments in the past decades. We construct a multipartite QKD protocol using teleportation by a Greenberger-Horne-Zeilinger entangled state. The latter is a frequently studied family entangled states in theory and experiments. Our protocol shows the security because the loss of any particles does not lead to the loss of information the sender wants to send to the receiver. Further, the classical messages cost in the protocol occur only among some particles. We also apply the unextendible product operator basis (UPOB) by performing them on high dimensional states, which are then teleported to the receiver. We stress that UPOBs are related to quantum nonlocality, which is associated with the local indistinguishability of orthogonal states. Hence our paper may contribute to the novel understanding of quantum nonlocality, as well as related quantum-information tasks such as state and operation discrimination.

A Secure Quantum Key Distribution Protocol Using Two-Particle Transmission

Pratapaditya Bej, Vinod Jayakeerthi

The evolution of Quantum Key Distribution (QKD) relies on innovative methods to enhance its security and efficiency. Unextendible Product Bases (UPBs) hold promise in quantum cryptography due to their inherent indistinguishability, yet they are underutilized in QKD protocols. This work introduces a protocol utilizing UPBs to establish quantum keys between distant parties. Specifically, we propose a protocol utilizing a $3\times 3$ tile UPB, where Alice sequentially transmits subsystem states to Bob through quantum channels. The protocol's security is underpinned by the no-cloning theorem, prohibiting the cloning of orthogonal states. We analyze potential attacks, including intercept-resend and detector blinding attacks when quantum channels are noiseless, and discuss the challenges posed by the indistinguishability of our protocol for eavesdroppers, thereby enhancing QKD security.

Revolutionizing Quantum Communication through Quantum Teleportation Techniques

Sanchi Agarwal, Ayon Somaddar, Neeru Bala

Quantum Key Distribution protocols have been essential for the purpose of creating secure channels for long-distance transmission of quantum information. On the basis of ideas of quantum teleportation, this paper presents a novel quantum communication protocol utilizing the quantum entanglement and classical communication channels. Also, this paper aims to increase key generation rate and distance, achieve longer communication distances and higher key production compared to traditional QKD methods, improve resilience against eavesdropping and optimize system performance. Quantum teleportation ensures the secure transfer of quantum states without exposing them to potential eavesdropping or interception, offering a higher level of security compared to traditional qubit-based protocols. This involves a thorough investigation of the Qiskit circuit implementations, operational procedures, and mathematical underpinnings of the protocol. Also, a thorough study of the protocol’s performance with respected to some of the existing protocols like BB84, E91 and others using various metrics like QBER, key generation rate, adversarial resilience and. This project advances Quantum Key Distribution systems and established the foundation for secure quantum communication networks.

ENCRYPTION-BASED NETWORKING QUANTUM TELEPORTATION WITH TRIPLET GREENBERGER–HORNE–ZEILINGER STATES

Ying Guo, Guihua Zeng

An encryption-based networking quantum teleportation scheme is proposed for the secure quantum communication network based on the novel networking quantum key distribution (NQKD) with the Greenberger–Horne–Zeilinger (GHZ) state. The security is exactly guaranteed via the entanglement of the GHZ quantum system. In the process of quantum teleportation, the server Charlie prepares the GHZ states and the users exploit the four local unitary operations corresponding to the keys shared aforehand to encrypt/decrpt for the initial messages. One legal user can communicate with another on the network securely as they may perform a quantum privacy application on the encrypted quantum states transmitted in quantum channel. Its intrinsic efficiency is high as almost all the instances are useful and each GHZ state can carry two different encrypted single-qubit states. To reconstruct these transmitted messages, the users exploit Bell measurement and perform local operations with respect to the shared keys in NQKD, which will improve its security in a noise quantum channel.

Quantum key distribution by quantum energy teleportation

Shlomi Dolev, Kazuki Ikeda, Yaron Oz

Quantum energy teleportation (QET) is a process that leverages quantum entanglement and local operations to transfer energy between two spatially separated locations without physically transporting particles or energy carriers. We construct a QET-based quantum key distribution (QKD) protocol and analyze its security and robustness to noise in both the classical and the quantum channels. We generalize the construction to an $N$-party information sharing protocol, possessing a feature that dishonest participants can be detected.

An efficient quantum key distribution protocol with orthogonal product states

Yu‐Guang Yang, Wen Qiao-yan

An efficient quantum key distribution (QKD) protocol with orthogonal product states in the 3 ⊗ 3 Hilbert space is presented. The sender, Alice, disorders the orthogonal product state sequence and sends it to Bob. After Alice has published the matching information of the particle sequence, Bob recovers the correct correspondences and makes an orthogonal measurement on the orthogonal product states to obtain the information sent by Alice. Finally, security analysis is also made.

Efficient discrimination schemes for unextendible product bases with strong quantum nonlocality

Qiqi Feng, Huaqi Zhou, Limin Gao

Entanglement is a central resource in quantum information science, and it is therefore important to design local discrimination protocols that minimize entanglement cost. In this paper, we propose several entanglement-assisted discrimination schemes for the local discrimination of a representative strongly nonlocal unextendible product basis (UPB) in a \(3\otimes 3\otimes 3\) system. By exploiting the structure of the UPB and the properties of maximally entangled resources, we generalize the protocols to a family of strongly nonlocal UPBs in \(d\otimes d\otimes d\) systems. In particular, we show that these UPBs can be perfectly distinguished using two bipartite maximally entangled states, distributed between different pairs of parties, without employing quantum teleportation. We further compare the total supplied and average consumed entanglement under a clearly specified accounting convention. The results demonstrate that avoiding teleportation can reduce the required entanglement in suitable resource-allocation scenarios and clarify the operational role of low-dimensional maximally entangled resources.
