Non-classical quantum technologies that rely on manipulation of quantum states and exploitation of quantum superposition and entanglement are approaching a level of maturity sufficient to contemplate commercialization as the basis of practical devices for sensing, communications, navigation and other applications in the relatively near-term. However, realization of such technologies is dependent upon the development of appropriate Quantum Systems Engineering (QSE) approaches. It is clear that whilst traditional systems engineering will support much of the integration need, there are aspects associated with system of interest definition, system modelling, and system verification where substantial advances in the systems engineering approach are required. This paper lays out in detail the challenges associated with Quantum Enabled Systems and Technologies (QEST) and analyses the adequacy of systems engineering processes and tools, as defined by the Systems and Software Engineering lifecycle standard (ISO/IEC/IEEE 15288), to meet these challenges. The conclusions of this paper provide an outline agenda for systems research in order to engineer QEST.

Quantum mechanics has emerged as one of the most transformative scientific revolutions of the 20th and 21st centuries, extending far beyond its initial theoretical foundations into practical applications across engineering, materials science, information technology, and nanotechnology. Its principles, such as wave�particle duality, superposition, and entanglement, form the backbone of modern innovations like quantum computing, quantum cryptography, semiconductor devices, and energy-efficient nanomaterials. This paper investigates the role of quantum mechanics in advancing technological frontiers, with an emphasis on engineering domains such as electronics, computing, and material design. A detailed discussion on quantum principles, their mathematical representation, and their translation into applied engineering technologies is presented. By linking theoretical constructs to real-world devices and emerging applications, this work highlights the significance of quantum mechanics as not only a fundamental science but also as a driver of future innovation.

The exciting possibilities in the field of new quantum technologies extend far beyond the well-reported application of quantum computing. Precision timing, gravity sensors and imagers, cryptography, navigation, metrology, energy harvesting and recovery, biomedical sensors and imagers, and real-time optimisers all indicate the potential for quantum technologies to provide the basis of a technological revolution. From the field of Systems Engineering emerges a focused strategy for the development cycle, enabling the existence of hugely complex products. It is through the adoption of systems thinking that the semiconductor industry has achieved massive industrial and economic impact. Quantum technologies rely on delicate, non-local and/or entangled degrees of freedom - leading to great potential, but also posing new challenges to the development of products and industries. We discuss some of the challenges and opportunities regarding the implementation of Systems Engineering and systems thinking into the quantum technologies space.
