High-Performance NOON State from a Quantum Dot Single Photon for Supersensitive Optical Phase Measurement

Photonics
We investigate the utilization of advanced single photons produced by quantum dots (QDs) in a microcavity for quantum metrology. Through the integration of lateral excitation and the Purcell effect in an Fabry–Perot microcavity, we realized single-photon

Quantum Error-Corrected Non-Markovian Metrology

PRX Quantum
Quantum metrology aims to maximize measurement precision on quantum systems, with a wide range of applications in quantum sensing. Achieving the Heisenberg limit (HL)—the fundamental precision bound set by quantum mechanics—is often hindered by noise ...
