Quantum entanglement experiments hinge on two things: the optics chain, which sets the quality of the entangled state, and the single-photon detectors, which define how reliably you can measure it. This article highlights best-practice setups, proven optical stacks, and how to select detectors for different scenarios. Why optics and detectors matter Bell-state fidelity: high indistinguishability […]

Optics for optical quantum computing are the key to ultra-fast computing system that work at— literally— the speed of light.
