Magnetic Gradient Fluctuations from Quadrupolar ^{73}Ge in Si/SiGe Exchange-Only Qubits

Magnetic Gradient Fluctuations from Quadrupolar ^{73}Ge in Si/SiGe Exchange-Only Qubits

We study the time-fluctuating magnetic gradient noise mechanisms in pairs of Si/SiGe quantum dots using exchange echo noise spectroscopy. We find through a combination of spectral inversion and correspondence to theoretical modeling that quadrupolar precession of the ^{73}Ge nuclei play a key role i...
