In this course, you will explore in detail the one-way quantum computing model. This model is one of the most promising in terms of practical implementation. In addition, you will understand what continuous-variable quantum computation is and how this type of computation differs from the usual computations with qubits. In addition, you will explore in detail the methods of quantum error correction that can be applied to all models of quantum computation. The authors of the course belong to the theoretical quantum-optical school of St.
