"Quantum Engineering" covers the theory, design, fabrication and applications of quantum coherent solid-state structures. This updated and expanded second edition provides a self-contained presentation of the theoretical methods and experimental results in both first and second waves of quantum technology innovation. Topics span the quantum theory of electric circuits, theoretical methods of quantum optics in application to solid-state circuits, the quantum theory of noise, decoherence and measurements, Landauer formalism for quantum transport, the physics of weak superconductivity and the physics of two-dimensional electron gas in semiconductor heterostructures. The author introduces microscopic ion- and defect-based qubits, currently among the most successful platforms for quantum computation and quantum sensing. Reflecting the significant progress of quantum hardware, state-of-the-art implementations such as quantum metamaterials and quantum reservoir computing are also added to the discussion. Written for graduate students in physics, this book also serves electronic engineers working in quantum engineering.

In this book, I concentrate on the two directions in quantum engineering, using as building blocks superconducting qubits and qubits based on two-dimensional electron gas (2DEG). The reason is partly subjective – this is where my expertise is – and partly objective – these two kinds of devices are well understood from the theoretical point of view and are being successfully fabricated and investigated by the experimentalists, using the rich toolset of solid-state physics. This allows me to illustrate the theoretical methods with actual experimental data that more often than not quantitatively agrees with theoretical predictions (which is a must for any kind of “engineering”). Being a theorist, I can only discuss the theoretical part of the toolset, which helped keep the volume of this book reasonable. Quantum engineering takes its theoretical tools from many, rather distant, areas of theoretical physics, and I restricted the content to the most useful and widely used techniques. The goal was to provide the reader with enough technical information to be able to deal with current research papers and to start their own work in this field.
