Summary: This study aims to design a highly nonlinear substitution-permutation network using the blotch symmetry of quantum spin states on the Galois field GF(2(8)). The efficiency of the proposed methodology was evaluated using common and advanced measures for performance, randomness, and cryptanalytics. The outcomes validate the effectiveness of the generated nonlinear confusion components for block ciphers and their higher cryptographic strength compared to state-of-the-art techniques.

Summary: In this study, a class of two-level multi-particle GHZ states is introduced, and entanglement swapping between Bell states and GHZ states in qubit systems is investigated. Formulas for entanglement swapping in any number of qubit systems are provided, along with a series of detailed entanglement swapping schemes. Applications of these schemes in quantum information processing are illustrated through proposed quantum protocols for quantum key distribution, quantum secret sharing, and quantum private comparison.

Summary: Ghost imaging is an indirectly optical imaging technique that allows acquiring sharp images of unknown objects hidden in harsh environments. In this study, a novel ghost communication approach is proposed based on computational ghost imaging and image segmentation. The approach conceals a part of the encrypted image information in an illuminating speckle pattern and encodes the other part into an intensity vector using a bucket detector. Experimental verification reveals the feasibility of the proposal, vulnerability to eavesdropping, and resistance to noise attacks. The results show that the security can be significantly enhanced by introducing the encrypted speckle in the proposed ghost communication approach.

Summary: Quantum technology, particularly quantum machine learning, offers substantial advantages over conventional methods in terms of efficiency and effectiveness. By conducting experiments with quantum processors, we have demonstrated the exponential advantage of quantum machines in predicting physical properties, performing quantum principal component analysis, and learning about physical dynamics. The resources required for achieving this advantage are also relatively modest in some cases.

Summary: Blind quantum computation (BQC) allows users with limited quantum abilities to complete tasks with the aid of a remote quantum server while keeping their information hidden. This paper introduces a new BQC model where users only need to implement single-qubit gates. A specific protocol is proposed to demonstrate the feasibility of this model and answer the question of whether a verified BQC protocol using only single-qubit gates can be designed.

Summary: Quantum entanglement is crucial for the development of quantum computation, communications, and technology. The controlled SWAP test is shown to be efficient for detecting entanglement of pure states and distinguishing entanglement classes, with the concurrence of two-qubit states related to the test's output probabilities. A multipartite measure of entanglement is proposed, and the average number of copies of the test state required to detect entanglement decreases for larger systems, remaining robust to small errors.

Summary: Digital communication has revolutionized the modern era, making communication easier but also opening up opportunities for adversarial attacks. While the BB84 quantum secret-key sharing protocol is resistant to eavesdropping attacks, it faces challenges such as vulnerability to impersonation attacks and slow secret-key distribution. To address these challenges, a new protocol combining image-based CAPTCHA and BB84 is proposed, which is secure against impersonation attacks and more efficient in terms of communicated qubits.
