Though research on quantum computing continues at a good pace, learning quantum computing requires a deep and clear level of knowledge of a range of domains that diverge from classical computer science. There are not quantum computing interfaces that facilitate learning this new paradigm, only those to illustrate some quantum computations with some accompanying documentation. Moreover, in this documentation, science is mixed with technology without a clear distinction between the underlying mathematics and physics concepts. We consider that this must be addressed in the first place in order to create proper learning environments that go beyond performing calculations without facilitating the understanding of the core of quantum computing concepts and their implications. This is a new research line, dealing with the design of quantum computing interfaces integrating science and technology.

Quantum computing has emerged as one of the most transformative technological developments of the twenty-first century. By exploiting the fundamental principles of quantum mechanics—namely superposition, entanglement, and measurement—quantum computers offer the potential to address problems that are beyond the practical reach of classical computing systems. As the field advances from theoretical exploration to real-world implementation, the demand for clear, structured, and comprehensive educational resources continues to grow. This book presents a systematic and accessible introduction to quantum computing, beginning with the essential concepts of classical information and computation and progressively advancing toward modern quantum algorithms and communication protocols. The initial chapters establish a strong foundation in classical bits, logic gates, Boolean algebra, reversible logic, and computational complexity, providing the conceptual bridge necessary to understand quantum computation. The discussion then moves to the quantum bit (qubit), examining its behavior through superposition, measurement, Bloch sphere representation, and physical realization. Special emphasis is placed on linear algebra as the mathematical framework underpinning quantum computing. Through this approach, readers are guided to develop an intuitive yet rigorous understanding of quantum states, quantum gates, and circuit-based computation. The text further extends these ideas to multi-qubit systems, quantum entanglement, universal gate sets, and quantum error correction, integrating theoretical principles with practical insights. To support experiential learning, the book incorporates hands-on exposure to leading quantum programming platforms, including IBM Quantum, OpenQASM, and Qiskit. These sections connect theory with practice, enabling readers to design, simulate, and execute quantum circuits on both simulators and real quantum hardware. Subsequent chapters explore key quantum communication protocols such as superdense coding, quantum teleportation, and quantum key distribution, followed by an in-depth treatment of foundational quantum algorithms including Deutsch–Jozsa, Grover’s search, Simon’s algorithm, and Shor’s factoring algorithm. This text is intended for undergraduate and postgraduate students, research scholars, and industry professionals seeking a coherent and structured pathway into quantum computing. No prior knowledge of quantum mechanics is assumed, although familiarity with linear algebra and classical computation will enhance comprehension. Each chapter is carefully organized to promote conceptual clarity, supported by illustrative examples, circuit diagrams, and concise summaries. Beyond explaining the principles and mechanisms of quantum computation, this book aims to inspire readers to engage with the future of the field—whether through academic research, industrial application, or interdisciplinary innovation. As quantum technologies continue to evolve, it is hoped that this text will serve as a dependable guide and a meaningful entry point into the quantum era.

Quantum computing is poised to revolutionize some critical intractable computing problems; but to fully take advantage of this computation, computer scientists will need to learn to program in a new way, with new constraints. The challenge in developing a quantum computing curriculum for younger learners is that two dominant approaches, teaching via the underlying quantum physical phenomenon or the mathematical operations that emerge from those phenomenon, require extensive technical knowledge. Our goal is to extract some of the essential insights in the principles of quantum computing and present them in contexts that a broad audience can understand.
Abstract The emerging field of Quantum Computing (QC) is novel for most K12 educators. Fundamental understandings of QC rely on advanced mathematics and physics. Therefore, why is a middle or high school introduction to QC relevant or needed? In our local area, the Pennsylvania (PA) Department of Education specifies that PA science teachers implement learning experiences that allow students to understand the nexus of how societal needs create a demand for new technologies that in turn advance scientific knowledge and impact society [1], that science teachers create opportunities for students to engage in computational thinking and mathematics within authentic science and engineering contexts [2], and that mathematics pedagogy supports students to model with mathematics and make sense of complex problems [3]. To fulfill these existing learning aims, we present a collaborative curriculum development project based on our interdisciplinary research in which we develop quantum computing methods and tools for therapeutic drug discovery. The team includes faculty from medicine, quantum computing, machine learning, and science education. The curriculum development work aims to develop resources for middle and high school (U.S. grades 6 – 12) teachers to facilitate an introduction to Quantum Information Science (QIS) and QC, embedded in existing learning aims including mathematical, scientific, and engineering practices and concepts in statistics and probability, the natural sciences, and computing. We therefore demonstrate a proof-of-concept paper for how an introduction to QC designed for teachers and students in middle and high school can be responsive to disciplinary science and math learning goals (e.g., interpreting a distribution of quantum states and decoding it into viable molecular structures) and situated in contexts of emerging quantum technologies. The educational resources provide a developmentally-appropriate approximation [4] of the drug discovery goals of the project and utilize existing cloud-based quantum infrastructure from IBM (IBM Quantum Experience), making the QIS concepts accessible and useful in the middle and high school contexts in relation to these existing discipline-based learning goals. The associated professional development (PD) will foster a pathway for teachers to engage with scientists and engineers around unfinished problems, supporting an epistemological stance toward science that aligns with interdisciplinary negotiations and model-based reasoning characteristic of ongoing scientific research. This, at its most basic level, supports teachers and students to engage with technological innovation as a form of scientific literacy. The teacher toolkit will support practitioners to visualize qubit states and facilitate learning activities that address how QC is an ongoing engineering endeavor, driven by societal needs for new technologies, and enabling QIS applications that young learners can authentically engage in.

As quantum technologies gain importance across scientific and societal domains, understanding the foundational principles driving their development is increasingly crucial. While much work has been devoted to defining essential knowledge and curriculum content for quantum technologies at various educational levels, less attention has been paid to how the Second Quantum Revolution is shaping the nature of quantum computation in terms of its foundational epistemic aims and values. The paper presents a conceptual account of the nature of quantum computation through document analysis of foundational research papers. Using the lens of the Family Resemblance Approach to the nature of science, it uncovers the core epistemic aims and values characterizing the domain of quantum computation. By applying this analytical framework, the study identifies both predetermined epistemic aims and values (e.g., objectivity and accuracy) and emergent subcategories (e.g., materiality of information and efficiency) relevant to quantum computation. The document analysis contributes to the literature on the nature of science in general and to the characterization of quantum computation as a domain in particular. Furthermore, the analysis brings to light implicit epistemic aims and values that guide practitioners in a scientific domain to the foreground, which often remain unarticulated in educational contexts. The findings include 17 instances of epistemic aims and values of quantum computation generated from an analysis of significant research papers in the field. By systematically generating these epistemic aims and values, the study provides a nuanced and explicit approach to characterizing the nature of quantum computation, enabling educators to incorporate these themes into curriculum design, teaching, and learning. Some implications for quantum technologies education are discussed.
