Quantum Computation, Communication and Cryptography

Dear Colleagues,

The subject area of applications involving quantum mechanics beyond the limits of classical physics has grown tremendously in the past decade, particularly regarding the theory and application of quantum entanglement and the superposition of quantum states. The representation of quantum states as quantum bits (qubits) as well as the transport and processing of quantum information has also become a leading area of research. In this Special Issue, the focus is on quantum computation, communications, cryptography, and the integration of those items. Articles focusing on theory as well as experimental results are encouraged. Topics of interest include, but are not limited to, the following topics. Authors are encouraged to combine topics of interest in a single paper where appropriate.

1. Quantum Computing:
   1. Architectures of new quantum computers;
   2. Benchmarks of quantum computers;
   3. Assessing the theoretical limits of quantum computers and computing;
   4. The nexus of artificial intelligence and quantum computing;
   5. Biologically inspired quantum computing;
   6. Interfaces between the quantum computing world and the classical computing world;
   7. Photonic quantum computing;

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. Entropy 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 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.
