Entangled Light

Scientists use precisely controlled lasers, mirrors, beam splitters, detectors, and optical components to create and manipulate entangled photons — the working basis of quantum teleportation.

How It Works

In a typical setup, a source laser generates pairs of entangled photons, which are then routed through a series of optical components designed to preserve their quantum state across a measurable distance.

Why It Matters

The technique underpins early quantum communication and quantum computing research, and represents one of the clearest experimental demonstrations of quantum entanglement observable today.
