| Zusammenfassung≠ | Surface Code is a two-dimensional topological quantum error-correcting code that protects quantum information through geometric redundancy. Introduced by Alexei Kitaev in 2003, surface code is considered the leading candidate for large-scale fault-tolerant quantum computing due to its high error thresholds and feasibility on two-dimensional qubit arrays. | Quantum Key Distribution (QKD) BB84 is a cryptographic protocol allowing two parties to establish a shared secret key using quantum mechanics. Proposed by Bennett and Brassard in 1984, BB84 provides information-theoretic security: an eavesdropper's presence is guaranteed to be detected, and the secret key is provably secure against unlimited computational power. |
