Special Issue Information

Dear Colleagues,

Quantum computing is an emerging technology that can perform high intensive computing tasks, which are needed in different areas, such as a data search from a high volume data repository, prime factorization, number theory, cybersecurity, polynomial evaluation, interpolation, machine learning, artificial intelligence and many more applications.

While quantum computing is still seeking its shape, its effect is seen in making magnificent strides in the field of computing, bringing into bare a new dimension of computing. Nevertheless, just like any other concept or field, it has some challenges and a lot of research and work need to be conducted to realize its capabilities and benefits.

This Special Issue focuses on the recent advances, and challenges, in developing large-scale, fault-tolerant quantum computers, capable of solving tomorrow’s growing computational needs. Original unpublished papers and review articles are invited on the following topics:

  • Quantum algorithms
  • Quantum circuits;
  • Quantum cryptography;
  • Quantum computation;
  • Quantum computer architecture;
  • Quantum information;
  • Quantum machine learning;
  • Quantum networks and communication;
  • Quantum programming;
  • Quantum simulation;
  • Complex dynamics;
  • Open quantum dynamics;
  • Computational complexity;
  • Quantum chaos;
  • Quantum complexity theory;
  • Quantum maps;
  • Quantum dots.

A crucial task for the systematic application of model-driven engineering techniques in the development of quantum software is the definition of metamodels, as a first step towards automatic code generation and integration with other tools. The importance is even greater when considering recent work where the first extensions to UML for modelling quantum circuits are emerging and the characterisation of these extensions in terms of their suitability for a model-driven approach becomes unavoidable. After reviewing the related work, this article proposes a unified metamodel for modelling quantum circuits, together with five strategies for its use and some examples of its application. The article also provides a set of constraints for using the identified strategies, a set of procedures for transforming the models between the strategies, and an analysis of the suitability of each strategy for performing common tasks in a model-driven quantum software development environment. All of these resources will enable the quantum software community to speak the same language and use the same set of abstractions, which are key to furthering the development of tools to be built as part of future model-driven quantum software development frameworks.

A quantum computer capable of running the Grover search algorithm, which reduces the complexity of brute-force attacks by a square root, has the potential to undermine the security strength of symmetric-key cryptography and hash functions. Recently, studies on quantum approaches have proposed analyzing potential quantum attacks using the Grover search algorithm in conjunction with optimized quantum circuit implementations for symmetric-key cryptography and hash functions. Analyzing quantum attacks on a cipher (i.e., quantum cryptanalysis) and estimating the necessary quantum resources are related to evaluating post-quantum security for the target cryptography algorithms. In this paper, we revisit quantum implementations of CHAM block cipher, an ultra lightweight cipher, with a focus on optimizing the linear operations in its key schedule. We optimized the linear equations of CHAM as matrices by applying novel optimized decomposition techniques. Using the improved CHAM quantum circuits, we estimate the cost of Grover’s key search and evaluate the post-quantum security strength with further reduced costs. Full article
