English edition of the book edited and written by members of aQuantum. In the book, the authors state that, for quantum software to be truly useful for the industry, it must be developed according to the best practices of Software Engineering. In the different chapters of the book this statement is unpacked with the aim of showing, from different angles, that only professional quantum software development can provide the industry with what it expects from it: high-quality, secure, extensible, high performance, high scalability and to ensure the investment made in it.

Quantum annealing software has gained a certain market penetration, demonstrating a good performance for optimization problems. However, there are no reverse engineering techniques with which to discover the underlying optimization problem definitions (the Hamiltonian functions to be minimized). This paper presents a dynamic analysis technique for D-Wave (Python) programs with which to reverse Hamiltonian expressions, and which are additionally represented according to the Knowledge Discovery Metamodel.

Article in which the authors present a complete example of integrating a QRNG circuit with a classic software application. In the example, the classic client will be responsible for calling the quantum circuit and collecting and post-processing the data. In QuantumPath® this process will be carried out in an agnostic way, starting from the design of the circuit (which once designed and available in QPath® can be reused whenever the client needs it), its control flow, and the encoding of the result, and the client will be able to launch the execution on any of the quantum computers available on the platform.

Quantum computing is the latest revolution in computing and will probably come to be seen an advance as important as the steam engine or the information society. In the last few decades, our understanding of quantum computers has expanded and multiple efforts have been made to create languages, libraries, tools, and environments to facilitate their programming. Nonetheless, quantum computers are complex systems at the bottom of a stack of layers that programmers need to understand.

The design of quantum software poses two main challenges: the modelling of software quantum elements must be done in high-level modelling languages; and the need to further develop so-called “hybrid information systems”, which combine quantum and classical software. To address these challenges, authors first propose a quantum UML profile for analysing and designing hybrid information systems. In comparison to certain other quantum domain-specific languages, this UML profile ensures compliance with a well-known international standard.

However, if industry is to boost the large-scale production of quantum software, an adequate quality level must be achieved and assured. In this sense, it is very important to consider quantum software quality platforms and products, and to create an effective quality environment for quantum software.

Nowadays, we are at the dawn of a new age, the quantum era. Quantum computing is no longer a dream; it is a reality that needs to be adopted. But this new
technology is taking its first steps, so we still do not have models, standards, or methods to help us in the creation of new systems and the migration of current ones. Given the current state of quantum computing, we need to go back to the path software engineering took in the last century to achieve the new golden age for quantum software engineering.
