| ergänzende Hinweise | Semiconductor-based quantum electronic devices and circuits play a pivotal role in the current development of processors for quantum computing, in particular since they can be integrated with the highly versatile existing microelectronics. Furthermore, these devices are fabricated using identical technology. The aim of this module is to introduce the students to the current concepts for semiconductor-based nanoelectronics for quantum applications, with a focus on electrostatically defined quantum dots and donors as the elementary quantum bits (qubits). The module will introduce the basic physics, the fabrication and the operational principles of these qubits and will discuss the current status of both approaches with respect, e.g., to relaxation, decoherence and scalability. For the manipulation of these qubits, magnetic resonance is used, which will be briefly reviewed. Specific topics will include: Review of fundamental semiconductor physics (crystal structure, band structure, excitons, dopants) Materials for semiconductor quantum electronics (Si, SiGe, III-V semiconductors including GaAs/AlGaAs, isotope engineering, heterostructures) Fabrication of devices for quantum electronics (molecular beam epitaxy, electron beam lithography, single ion implantation, STM lithography) Two-dimensional electron gases (electrostatics, diffusive and ballistic transport, g-factor) Review of spin physics (electron and nuclear spins, magnetic resonance, relaxation and decoherence)Electrostatically defined quantum dots (electronic transport, Coulomb diamond, single electron transistor, capacitance model, spin states, spin-to-charge conversion, Kondo effect) Spin interaction with the environment (spin orbit interaction, hyperfine interaction) Coupled quantum dots (electronic properties, spin blockade, hyperfine effects) Spin physics of dopants (g-factor, hyperfine coupling, quadrupole interaction) Electrically detected magnetic resonance Single donor spins (readout via SET, coupling of donors, hyperfine effects) Comparison of quantum electronic systems discussed Quantum processors (topologies, quantum state transfers, the current state-of-the-art of such processors, challenges) Hybrid quantum systems with microwaves, optical photons and/or phonons |
