The usefulness of most quantum computers is still significantly limited by the low number of qubits that hardware can support. But simple fiber optic cables – just like the ones used for broadband ...

Researchers developed a fiber-optic quantum random number generator that uses single-photon path superposition and a validated stochastic model to guarantee high-quality quantum randomness. Operating ...

Schematic diagram and microscopic observation of an optical fiber doped with rare-earth atoms. The fluorescence from the entire optical fiber can be seen. (b) Schematic diagram and microscopic ...
