“ Quantum sensing ” describes the use of a quantum system, quantum properties, or quantum phenomena to perform a measurement of a physical quantity. Historical examples of quantum sensors include magnetometers based on superconducting quantum interference devices and atomic vapors or atomic clocks. More recently, quantum sensing has become a distinct and rapidly growing branch of research within the area of quantum science and technology, with the most common platforms being spin qubits… 
Dissipation-Based Quantum Sensing of Magnons with a Superconducting Qubit.
TLDR
The experimentally demonstrate quantum sensing of a steady-state magnon population in a magnetostatic mode of a ferrimagnetic crystal using Ramsey interferometry with a sensitivity on the order of 10^{-3}  magnons/sqrt[Hz].
Quantum Sensing with a Single-Qubit Pseudo-Hermitian System.
TLDR
This work proposes a strategy to realize a single-qubit pseudo-Hermitian sensor from a dilated two-qu bit Hermitian system, and demonstrates its potential advantages to overcome noises that cannot be averaged out by repetitive measurements.
Quantum-enhanced measurements without entanglement
Quantum-enhanced measurements exploit quantum mechanical effects for increasing the sensitivity of measurements of certain physical parameters and have great potential for both fundamental science
Quantum control-enhanced sensing and spectroscopy with NV qubits in diamond
TLDR
This work explores quantum control tools to improve the performance of a NitrogenVacancy center as a single-qubit sensor of ultra-weak magnetic fields in noisy environments and exploits optimal quantum control based on a set of numerical methods to optimize the temporal dependence of the sensor driving field adapted to quantum sensing purposes.
Quantum-enhanced radiometry via approximate quantum error correction
Quantum sensing based on exotic quantum states is appealing for practical metrology applications and fundamental studies. However, these quantum states are vulnerable to noise and the resulting
Entanglement-based single-shot detection of a single magnon with a superconducting qubit
TLDR
Using a superconducting qubit as a quantum sensor, a single magnon is detected in a millimeter-sized ferrimagnetic crystal with a quantum efficiency of up to 0.71, establishing the single-photon detector counterpart for magnonics.
Advances in photonic quantum sensing
TLDR
The theoretical and experimental developments of quantum reading of classical data, quantum illumination of targets, and optical resolution beyond the Rayleigh limit are described.
Hybrid quantum systems with circuit quantum electrodynamics
The rise of quantum information science has provided new perspectives on quantum mechanics, as well as a common language for quantum engineering. The focus on platforms for the manipulation and
