Abstract:

The quantum switch is one of the simplest elements which can be analyzed in quantum circuits and in the field of connections inside quantum networks. Its task is to exchange the information between inputs A and B, i.e. the quantum information entering the switch’s input A is transmitted to output B, and analogously, the information from input B is passed to output A. During the seminar, we are going to present the construction of the switch and the analysis of its operating. We will show that the entanglement level is an invariant while the switch’s operating. Finally, challenges for further theoretical research and numerical experiments will be listed
