Seminar topic: “Quantum Computing Using Multilevel Systems”

Speaker: Aleksey Fedorov (Head of the group of Quantum Information Technologies, “Skolkovo”)

Abstract:

Quantum computers are computing devices that use quantum phenomena (such as quantum superposition and quantum entanglement) to solve problems. Quantum computing devices have the potential to outperform classical computers in a variety of tasks, such as cryptanalysis, complex system modeling, and machine learning. The presentation will provide an overview of various models of quantum computing, as well as the main applications of quantum computing devices. We will also consider a model of quantum computing using multilevel systems (qudits). The proposed model is based on a combination of several approaches. The first approach exploits the general relationship between the dimension of the qubits and their link topology, which is necessary for a scalable multi-qudit processor, where higher levels of qudits are used to replace auxiliary qubits. The second approach uses the decomposition of multi-level systems into a set of two-level systems. The application of the approach in current experiments with quantum information processing systems is discussed. The questions of the analysis of quantum computing devices in the context of the theory of open quantum systems will also be touched upon.
