Abstract summary: Superconducting micro-resonators in combination with quantum-limited Josephson parametric amplifiers lead to more than four orders of magnitude improvement in sensitivity of pulsed Electron Spin Resonance (ESR) measurements. We present a technique for coupling an ensemble of spins directly to a weakly nonlinear microwave resonator, which is engineered from a magnetic field-resilient thin superconducting film. We perform pulsed ESR measurements with a $1$pL effective mode volume and amplify the resulting spin signal using the same device, achieving a sensitivity of $2.8 times 103$ spins in a single-shot Hahn echo measurement at a temperature of 400

Abstract: The use of superconducting micro-resonators in combination with quantum-limited Josephson parametric amplifiers has in recent years lead to more than four orders of magnitude improvement in the sensitivity of pulsed Electron Spin Resonance (ESR) measurements. So far, the microwave resonators and amplifiers have been designed as separate components, largely due to the incompatibility of Josephson junction-based devices with even moderate magnetic fields. This has led to complex spectrometers that operate under strict environments, creating technical barriers for the widespread adoption of the technique. Here we circumvent this issue by inductively coupling an ensemble of spins directly to a weakly nonlinear microwave resonator, which is engineered from a magnetic field-resilient thin superconducting film. We perform pulsed ESR measurements with a $1$~pL effective mode volume and amplify the resulting spin signal using the same device, ultimately achieving a sensitivity of $2.8 \times 10^3$ spins in a single-shot Hahn echo measurement at a temperature of 400 mK. We demonstrate the combined functionalities at fields as large as 254~mT, highlighting the technique's potential for application under more conventional ESR operating conditions.

Kinetic Inductance Parametric Converter [0.0]
Parametric converters are used for amplifying and squeezing microwave signals in quantum computing and sensing. In current devices, the strong localized nonlinearity of the Josephson Junction limits the amplification and squeezing. A weak distributed nonlinearity can provide higher gain and dynamic range, when implemented as a kinetic inductance (KI) nanowire of a dirty superconductor.

Quantum sensors based on solid-state defects, in particular nitrogen-vacancy centers in diamond, enable precise measurement of magnetic fields, temperature, rotation, and electric fields. We introduce a cavity quantum electrodynamic (cQED) hybrid system operating in the strong coupling regime, which enables high readout fidelity of an NV ensemble. We demonstrate a broadband sensitivity of 580 fT/$sqrtmathrmHz$ around 15 kHz in ambient conditions.

Directional Josephson traveling-wave parametric amplifier via non-Hermitian topology [58.720142291102135]
Low-noise microwave amplification is crucial for detecting weak signals in quantum technologies and radio astronomy. Current amplifiers do not satisfy all these requirements, severely limiting the scalability of superconducting quantum devices. Here, we demonstrate the feasibility of building a near-ideal quantum amplifier using a homogeneous Josephson junction array and the non-trivial topology of its dynamics.

Measuring the magnon-photon coupling in shaped ferromagnets: tuning of the resonance frequency [50.591267188664666]
cavity photons and ferromagnetic spins excitations can exchange information coherently in hybrid architectures. Speed enhancement is usually achieved by optimizing the geometry of the electromagnetic cavity. We show that the geometry of the ferromagnet plays also an important role, by setting the fundamental frequency of the magnonic resonator.

We investigate the use of a split-ring resonator incorporated with an atomic-vapor cell to improve sensitivity and the minimal detectable electric field of Rydberg atom-based sensors. By combining EIT with a heterodyne Rydberg atom-based mixer approach, the SRR allows for the a sensitivity of 5.5$mu$V/m$sqrtrm Hz$, which is two-orders of magnitude improvement in sensitivity than when the SRR is not used.
