Abstract: Characterization of noise of a quantum harmonic oscillator is important for many experimental platforms. We experimentally demonstrate motional spin-locking spectroscopy, a method that allows us to directly measure the motional noise spectrum of a quantum harmonic oscillator. We measure motional noise of a single trapped ion in a frequency range from 200 Hz to 5 kHz with a power spectral density that resolves noise over two orders of magnitude. Coherent modulations in the oscillation frequency of the oscillator can be probed with a relative frequency sensitivity at the $10^{-6}$ level.

We measure the charge-noise spectrum of a Si/SiGe singlet-triplet qubit over nearly 12 decades in frequency. The noise is colored across the entire frequency range of our measurements, although the spectral exponent changes with frequency. Simple transport measurements can accurately characterize the charge noise over a wide frequency range in Si/SiGe quantum dots.

We suggest the measurement of the twist of a chiral mechanical element induced by a gravitational wave. The induced twist rotates a flat optical mirror on top of this chiral element, leading to the deflection of an incident laser beam. We estimate a gravitational wave strain sensitivity between 10-21/sqrtHz and 10-23/sqrtHz at around 10 kHz frequency.
