Terra Quantum's loss-control-based quantum key distribution system delivers quantum-safe keys over optical fiber, enabling network operators to secure critical infrastructure links.
Quantum computing isn’t waiting to become useful—its practical hybrid phase is already underway.

Illustration of the telecom single-photon device. A resonant pulsed laser (top left) excites a single quantum dot embedded within a photonic-crystal waveguide, and the dot emits telecom-wavelength photons one at a time into the on-chip circuit. Gold contacts apply the bias that stabilizes the dot's charge environment.

Schematic comparison of carrier injection through a) 1 + 2 and b) 2 + 3 quantum interference within a semiconductor. The higher-order 2 + 3 process concentrates carriers into a narrower range of momentum-space directions and produces a more directional photocurrent.
