Περιγραφή Μαθήματος

This is an elective course in the MSc in Quantum Computing and Quantum Technologies

The course for the spring semester 2025-26 is taught every Tuesday from 18:00-20:00 CET.

The purpose of this course is to introduce the student to quantum dynamics and quantum control and connect them with applications in quantum computing and quantum technologies. The course syllabus includes: 

The tools for describing quantum dynamics of closed and open quantum systems: Probability amplitude approach, Time-evolution operator, Density matrix approach.

Basic applications of quantum dynamics and quantum control: Quantum tunneling dynamics and coherent destruction of tunneling. Control of spin dynamics by external magnetic fields. Near-resonant excitation of closed and open two-level quantum systems by electromagnetic fields – π-pulse excitation. Decay and dephasing effects in driven two-level quantum systems.

Further applications of quantum control:  Weak field excitation, time-dependent perturbation theory, Fermi’s golden rule, and phase control (interference control). Adiabatic evolution for the control of quantum dynamics and rapid adiabatic passage. Shortcuts to adiabaticity (basic idea and examples) and Derivative Removal by Adiabatic Gate (DRAG). The quantum Zeno effect and dynamical decoupling. Dynamics of three-level quantum systems driven near resonant by electromagnetic fields and Stimulated Raman Adiabatic Passage (STIRAP). Optimal control of quantum dynamics (basic idea and examples). Quantum control with Lyapunov function. AI techniques and Machine Learning in quantum control.
