Presentation Title:
Mitigating Electrical and Magnetic Noise for Solid-State Spin Qubits
Presentation Abstract:
I will overview our work on color center qubits hosted in 4H-SiC, a wafer-scale semiconductor at the center of the power electronics industry. First, I highlight the opportunity for semiconductor device integration to enable near-transform limited quantum emission by eliminating electrical noise. Enabled by the first single-shot readout in this platform, I will then discuss our demonstration of world-record electron spin coherence times exceeding five seconds. By then simultaneously eliminating both magnetic and electrical noise, I describe our recent work that demonstrates the longest Hahn-echo time ever reported on any qubit, of over a minute, encoded in a nuclear spin. Finally, I will discuss the opportunities for these coherent spins for solid-state quantum sensing, photonic integration, and scalable quantum technology.
