Silicon quantum dots make excellent qubits due to their long coherence times, small pitch, and compatibility with CMOS technology. My work is focused on improving the readout of these devices using reflectometry and to develop architectures to scale up this technique. My goal is to understand the limits of readout fidelity and, ultimately, achieve single-shot readout necessary for quantum error correction algorithms.
I am also interested in scaling up quantum computers. Specifically, in developing strategies to reduce how the number of interconnections and control lines scales with the number of qubits.
I used to be unbeatable at Mario Kart.
