Symmetry in Quantum Computing, Quantum Information and Quantum Communication

Dear Colleagues,

Symmetry and its breaking exist widely in nature, attracting both Mathematicians and Physicists. In Physics, symmetries are applied to reveal conservation laws, study group theory, etc. Now, symmetry plays an important role in quantum information science. The concept of symmetry in quantum computing, quantum information, and quantum communication underscores the interconnectedness of these fields and highlights the importance of maintaining balance and coherence in quantum systems and processes.

Scientists design new quantum algorithms using both unitary and non-unitary operators that are related to systems with Hermitian and various non-Hermitian symmetries. Quantum simulation of typical non-Hermitian systems that are closely related to open and dissipative systems, including PT-, anti-PT, anyonic-PT symmetric systems, pseudo-Hermitian systems, etc., enables scientists to investigate these novel systems and properties using current quantum computers, such as fast evolution, state discriminations, highly efficient energy storage based on quantum, quantum statistics and thermal dynamics, etc. In quantum communication and cryptography, both symmetric and asymmetric cryptography are focused on for public security. Overall, this holistic view of symmetry contributes to the advancement and optimization of quantum science and technologies for various applications and industries.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) quantum information, quantum computing, quantum simulation, quantum communication, quantum algorithm design with unitary and nonunitary operators, quantum cryptography and cybersecurity, open and dissipative quantum systems, non-Hermitian quantum systems with different symmetries (PT symmetry, anti-PT symmetry, anyonic-PT symmetry, pseudo-Hermitian, etc.), quantum-based new energy storage and quantum battery, quantum thermal dynamics and quantum statistics, and quantum computers for all real-world applications.

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. Symmetry is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
