Special Issue "Quantum Information: Fragility and the Challenges of Fault Tolerance"
Deadline for manuscript submissions: closed (31 October 2019).
Interests: superconducting qubits; quantum computing; quantum simulation; quantum neural networks; biological networks; quantum effects in biology
The recent advances in scaling up quantum processors into the range of 50–100 qubits make quantum error correction (QEC) and fault tolerance urgent practical issues in order to achieve quantum advantage or even quantum supremacy. Interesting developments in regular QEC include new classes of codes, either in the qubit setting (topological, non-abelian, holographic…) or with continuous variables, such as Gottesman-Kitaev-Preskill (GKP) or cat-codes. However, universal fault-tolerant quantum computation based on QEC is not yet within reach. The near-term challenge is rather to make optimal use of available hardware and software resources. This requires developing useful characterization tools, typically involving the number, connectivity, and coherence of physical qubits, the available gate set, and the number of operations that can be run in parallel. On the software side, machine learning (ML) may be used for optimizing gate sequences, minimizing circuit depths, optimizing variational schemes. Other challenges involve new types of architectures, like dynamical complex systems based on (brain-inspired) adaptive quantum networks.

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 papers will be 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 100 words) can be sent to the Editorial Office for announcement on this website.
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 1600 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.
