Electrical Engineering (EE) and Quantum Mechanics (QM) have gone hand in hand for many years, with each field helping the other advance. Many developments in EE, like transistors, lasers, and Magnetic Resonance Imaging (MRI), rely on quantum mechanical effects for their fundamental operation. Similarly, development in EE enabled progress in experimental quantum physics. With devices and circuits shrinking to the nanoscale level, engineers have had to come across quantum phenomena directly. For example, at the 7-5 nm transistor technology nodes, the behavior of the transistor is significantly affected by quantum tunneling and energy quantization. Even though these effects were once negligible at the classical circuits design scale, they have now become increasingly difficult to manage as feature sizes approach atomic scales. Therefore, EE gave rise to the emerging field of quantum engineering by providing tools and techniques to harness, control, and measure quantum systems. This paper reviews the literature on how EE methods have impacted quantum mechanics’ research.

A clear introduction to quantum mechanics concepts Quantum mechanics has become an essential tool for modern engineering, particularly due to the recent developments in quantum computing as well as the rapid progress in optoelectronic devices. Engineering Quantum Mechanics explains the fundamentals of this exciting field, providing broad coverage of both traditional areas such as semiconductor and laser physics as well as relatively new yet fast-growing areas such as quantum computation and quantum information technology. The book begins with basic quantum mechanics, reviewing measurements and probability, Dirac formulation, the uncertainty principle, harmonic oscillator, angular momentum eigenstates, and perturbation theory. Then, quantum statistical mechanics is explored, from second quantization and density operators to coherent and squeezed states, coherent interactions between atoms and fields, and the Jaynes-Cummings model. From there, the book moves into elementary and modern applications, discussing such topics as Bloch theorem and effective mass theory, crystal orientation effects for zinc-blend and wurtzite Hamiltonian, and quantum entanglements and teleportation. There has been growing interest in the model of semiconductor lasers with non-Markovian relaxation. This book develops a non-Markovian model for the optical gain in semiconductor materials, taking into account the rigorous electronic band-structure and the non-Markovian relaxation using the quantum statistical reduced-density operator formalism. Many-body effects are taken into account within the time-dependent Hartree-Fock equations, and example programs based on Fortran 77 are provided for band-structures of zinc-blend quantum wells. Engineering Quantum Mechanics is intended for advanced undergraduate and graduate students in electrical engineering, physics, and materials science. It also provides the necessary theoretical background for researchers in optoelectronics or semiconductor devices.
Quantum mechanics is one of the most significant scientific theories in modern physics, concerned with the behavior of matter and energy at the atomic and subatomic scales. By introducing concepts such as the quantization of energy, wave–particle duality, the uncertainty principle, quantum superposition, and quantum entanglement, this theory has fundamentally transformed humanity's understanding of the underlying structure of the universe.
