The course also includes discussions on such fabrication techniques as laser-ablation, magnetron and ion beam sputter deposition, epitaxy for layer structures, rubber stamping for nanoscale wire-like patterns, and electroplating into nanoscale porous membranes. Finally, devices based on single- and multi-walled carbon nanotubes are presented with emphasis on their unique electronic and mechanical properties that are expected to lead to ground breaking industrial nanodevices. Discusses optical devices including semiconductor lasers incorporating active regions of quantum wells and self-assembled formation of quantum-dot-structures for new generation of semiconductor layers. Giant magnetoresistance (GMR) in multilayered structures are presented with their applications in hard disk heads, random access memory (RAM) and sensors. The course introduces basic single-charged electronics, including quantum dots and wires, single-electron transistors (SETs), nanoscale tunnel junctions, and so forth. The recent emergence of fabrication tools and techniques capable of constructing nanometersized structures has opened up numerous possibilities for the development of new devices with size domains ranging from 0.1 - 50 nm. The specific topics covered include quantum postulates, states, ensembles, density matrix, pure and mixed states, qubits, Pauli matrix, Bloch sphere, single-qubit states, rotation matrix in R3, Schmidt decomposition and state purification, orthogonal measurement, generalized measurement (POVM), unitary evolution operator, Krauss evolution operator, entanglement, EPR states, Bell inequality, dense coding, quantum teleportation, no cloning, EPR quantum key distribution, single-qubit quantum gates (Hadamard), reversible gates (Fredkin, Toffoli, Feynman), quantum Fourier transform (Shor’s algorithm), quantum search (Grover’s algorithm), physical realization examples including superconducting circuit QED, single electron spin qubit in quantum dot and selected device topics of recent development. This course introduces concepts and applications of quantum computing and covers basic quantum mechanics focused on two-level systems (qubit), basic principles and examples of quantum gates and some concrete examples of physical realization of quantum computers. ![]()
