Quantum Computing and Networking

Dear Colleagues,

Quantum computers such as IBM Q, Google Sycamore, and D-WAVE Advantage are built based on the phenomena of quantum superposition, quantum entanglement, and quantum tunneling. They perform computation on the basis of quantum bits or qubits. In contrast, traditional or classical computers perform computation on the basis of bits. A bit is either 0 or 1, but a qubit exists in a superposition of both 0 and 1, and only when measured does it clearly reveal the 0 or 1 state. Since the computing power of a quantum computer increases exponentially with the number of qubits, it has a computing power that cannot be surpassed by a classical computer, which is called quantum supremacy.

Based on technologies such as quantum-entanglement generation, quantum-entanglement swap, and quantum teleportation, quantum computers and classical computers are even interconnected to form quantum networks offering functionalities that classical networks cannot offer. For example, with quantum networking and quantum key distribution mechanisms, information can be transmitted or teleported between computers to achieve unhackable unconditional security. Furthermore, quantum computers can be clustered together to perform distributed quantum computation by accumulating their qubits together.

This Special Issue solicits submissions of papers related to quantum computing and quantum networking. The topics include but are not limited to quantum algorithms, quantum annealing algorithms, quantum-inspired algorithms, distributed quantum algorithms, quantum machine learning, quantum neural networks, quantum key distribution, quantum network routing, quantum network communication, and quantum network protocol designs, and quantum Internet of Things (QIoT).

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.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 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.
