We report on an elementary quantum network of two atomic ions separated by 230 m. The
ions are trapped in different buildings and connected with 520 (2) m of optical fiber. At each …

Cryptographic key exchange protocols traditionally rely on computational conjectures such
as the hardness of prime factorization to provide security against eavesdrop** attacks …

Quantum key distribution provides secure keys with information-theoretic security ensured
by the principle of quantum mechanics. The continuous-variable version of quantum key …
