Marina Kudra gives a talk at Qiskit Seminar Series

Marina Kudra gave a presentation for the Qiskit Quantum Information Science Seminar Series on March 5th, 2021. Her talk is available here.

Marina presented her research on improving the quality factor of aluminum 3D cavities. These cavities, when coupled to ancilla qubits, are a great system to store quantum information. She presented a comprehensive study of internal quality factors in a total of 17 cavities of different purity, resonance frequency, and size, subjected to different treatments. Using a recipe including wet etching and annealing, she could reproducibly obtain quality factors in excess of 80 million at the single-photon level, a state-of-the-art figure.

Here research is also published in Appl. Phys. Lett. 117, 070601 (2020) (Editor’s Suggestion).
