Abstract

fetched live from OpenAlex

Cryptography not only involves the sending of secret messages but also encompasses many protocols and procedures that provide privacy and security in the networked world. Likewise, quantum resources have the potential to enhance cryptography in ways that go beyond the well-known example of quantum key distribution. This review offers a classification of the main crypto primitives that are available quantum mechanically. It explains the security that they offer, including the sometimes significant limitations on their theoretical capabilities. Implementations using current photonic techniques are discussed.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
