Protected qubits in superconducting devices and materials

Superconducting devices and materials are the foundation for impressive progress in quantum computing technology. However, the protection of quantum information in superconducting architectures remains a significant obstacle towards a large-scale quantum computer. In this seminar, I will present my work towards new platforms for protecting quantum information in superconducting devices and materials. More specifically, in the first part of the seminar, I will discuss the  “Majorana Superconducting Qubit” device platform, which leverages topological superconductor islands as new superconducting circuit elements for robust quantum information processing [1,2]. In the second part of the seminar, I will provide an introduction to a complementary approach based on moiré materials as a new material platform for the topological superconductivity in layered 2D heterostructures [3,4].
