Superconducting circuits are a leading platform for quantum computing. Although they are cooled down inside of dilution refrigerators, the circuits themselves only reach 30 or 40mK at best, due to thermal noise. Improving the thermalization of these circuits is an ongoing challenge that impacts qubit initialization, control, decoherence and measurement. Full thermal modeling of these systems is difficult and thus experimentation is required to optimize circuit temperatures. I will experiment with different filtering, thermalization and attenuation techniques to minimize qubit coupling to thermal noise, as well as investigating how antenna modes of qubit geometry couple to high-frequency noise.

This SuperUROP is a unique opportunity to apply theory I have learned from physics classes, including the quantum mechanics sequence 8.04-8.06, in a laboratory setting. Moreover, I hope to become proficient in all the intricate details that go into designing good superconducting qubits, and I am most excited to test hypotheses and see what happens.
