Quantum Secure Multiparty Computation and Communication: from Mathematical Foundations to Modern Applications

Dear Colleagues,

With the rapid advancement of quantum computing and distributed communication technologies, secure multiparty computation and communication protocols have become increasingly important in both theoretical research and real-world applications. Quantum secure multiparty computation protocols extend classical secure computation paradigms by leveraging quantum mechanical principles such as superposition, entanglement and the no-cloning theorem, enabling multiple participants to collaboratively compute functions or exchange information while preserving privacy, correctness and resistance against increasingly powerful adversaries. These developments are expected to play a crucial role in next-generation secure communication infrastructures, distributed intelligence, cloud computing, blockchain systems and quantum networks.

At the same time, the design and deployment of quantum secure communication and multiparty applications introduce substantial mathematical, computational and physical challenges. Ensuring the correctness, privacy, fairness and robustness of these protocols under realistic quantum adversarial models requires rigorous theoretical foundations and systematic verification methodologies. Mathematical tools from cryptography, information theory, linear algebra, complexity theory and quantum mechanics, together with formal methods for protocol verification and security analysis, provide essential frameworks for understanding and validating these emerging systems.

This Special Issue aims to bring together cutting-edge research on quantum secure multiparty computation and communication, spanning fundamental mathematical theories to practical implementations and modern applications. We welcome original contributions addressing novel cryptographic constructions, quantum communication protocols, formal security models, verification techniques, implementation frameworks and interdisciplinary applications. Topics of interest include, but are not limited to, quantum privacy-preserving computation, quantum secret sharing, distributed quantum cryptography, quantum communication networks, quantum authentication and signatures, privacy-preserving quantum protocols, post-quantum and hybrid secure communication systems, formal verification of quantum communication protocols, quantum blockchain security, quantum-assisted federated learning and security analysis under realistic quantum attack models.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Mathematics is an international peer-reviewed open access semimonthly journal published by MDPI.
