- Abstract summary: Single-spin to photon coupling strengths up to $sim 3kHz$ are observed.
The single shot sensitivity is $120 pm 24$spins/Hahn echo, corresponding to $approx 12 pm 3$spins$/sqrttextHz$ for repeated acquisition.

- Abstract: We report electron spin resonance measurements of donors in silicon at
millikelvin temperatures using a superconducting $LC$ planar micro-resonator
and a Josephson Parametric Amplifier. The resonator includes a nanowire
inductor, defining a femtoliter detection volume. Due to strain in the
substrate, the donor resonance lines are heavily broadened. Single-spin to
photon coupling strengths up to $\sim 3~\text{kHz}$ are observed. The single
shot sensitivity is $120 \pm 24~$spins/Hahn echo, corresponding to $\approx 12
\pm 3$~spins$/\sqrt{\text{Hz}}$ for repeated acquisition.

We observe the emission of bunches of $k geqslant 1$ photons by a circuit made of a microwave resonator in series with a voltage-biased tunable Josephson junction.
The bunches are emitted at specific values $V_k$ of the bias voltage, for which each Cooper pair tunneling across the junction creates exactly k photons in the resonator.

Mechanical Element and a Short Unstable Optical Cavity [59.66860395002946]
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.
