Entanglement is an essential property of multipartite quantum systems, characterized by the inseparability of quantum states of objects regardless of their spatial separation. Generation of entanglement between increasingly macroscopic and disparate systems is an ongoing effort in quantum science, as it enables hybrid quantum networks, quantum-enhanced sensing and probing of the fundamental limits of quantum theory. The disparity of hybrid systems and the vulnerability of quantum correlations…

Noisy Quantum Metrology Enhanced by Continuous Nondemolition Measurement.
It is shown that continuous quantum nondemolition measurement of an atomic ensemble is able to improve the precision of frequency estimation even in the presence of independent dephasing acting on each atom, and that such superclassical scaling holds for different values of dephase and monitoring efficiency.
Calibration of spin-light coupling by coherently induced Faraday rotation.
The method named Coherently Induced FAraday Rotation (CIFAR) is introduced, suited for both continuous and pulsed readout of the spin oscillator, relying only on applying a known polarization modulation to the probe laser beam and detecting a known optical polarization component.
