Graduate Student Seminar with Kaiwen Zheng on Superconducting Quantum Computing Platforms

Superconducting qubit is THE best quantum computing platform as of 2022. It is fast, accurate, easily scalable, but not entirely perfect. One of its shortcomings is that the quantum states in these qubits do not last as long compared to other competing platforms such as semiconductor electron qubits. One remedy comes in the shape of a hybrid system where the benefits of superconducting qubits are kept, and a second long-living platform is used as its memory. Unfortunately, the traditional method of making an electron qubit in semiconductors will make superconducting qubits inoperable. In this talk, I will share recent experimental progress to overcome this issue carried out by the Murch group.
