Tracking small transverse displacements of an optical beam with ultra-high accuracy is a fundamental problem underlying numerous important applications ranging from pointing, acquisition and tracking for establishing a lasercom link, to atomic force microscopy for imaging with atomic-scale resolution. Determining what is the optimal quantum-optical probe and the best achievable sensitivity of measuring a small transverse optical beam displacement, is the fundamental question central to these…

Entanglement-enhanced estimation of a parameter embedded in multiple phases
Quantum enhanced sensing promises to improve the performance of sensing tasks using non-classical probes and measurements using far less scene-modulated photons than possible by the best classical
Photonic quantum metrology
TLDR
This work discusses the current experimental and theoretical challenges, and the open questions towards implementation of photonic quantum sensors with quantum-enhanced performances in the presence of noise, in the research area of multiparameter quantum metrology, where multiple parameters have to be estimated at the same time.
Distributed quantum sensing in a continuous-variable entangled network
Networking is integral to quantum communications 1 and has significant potential for upscaling quantum computer technologies 2 . Recently, it was realized that the sensing performances of multiple
Quantum-Enhanced Fiber-Optic Gyroscopes using Quadrature Squeezing and Continuous-Variable Entanglement
For fiber-optic gyroscope designs, we analyze the quantum enhancement from quadrature-squeezed and entangled optical probe states for rotation sensing. Under realistic experimental constraints and
