Nonlinear Quantum Measurement May be Better than Linear Measurement

One of the important tasks for quantum physics researchers and engineers is designing more sensitive instruments to study the tiny fields and forces that govern the world we live in. The most precise measuring instruments devised to date, such as atomic clocks or gravitational wave detectors, are interferometric in nature and operate according to the laws of quantum mechanics.

Researchers Demonstrate Strong Coupling via Dark State Resonances in Coupled-Cavity Quantum Electrodynamics System

Coherent light-matter interaction at the single photon level is a long-standing goal for quantum operations. To reach such strong coupling regime, previous studies mainly focus on improving the quality (Q) factor and reducing the mode volume (V) of the same optical resonators, but they have already reached their limits due to current fabrication and other technological restrictions.
