Quantum cryptography exploits principles of quantum physics for the secure processing of information. A prominent example is secure communication, i.e., the task of transmitting confidential messages from one location to another. The cryptographic requirement here is that the transmitted messages remain inaccessible to anyone other than the designated recipients, even if the communication channel is untrusted. In classical cryptography, this can usually only be guaranteed under computational hardness assumptions, e.g., that factoring large integers is infeasible. In contrast, the security of quantum cryptography relies entirely on the laws of quantum mechanics. Here we review this physical notion of security, focusing on quantum key distribution and secure communication.

  1. On estimating operator norm distance, with optimal trace distance estimation when one state is pure

    quant-ph 2026-07 accept novelty 7.0 of 10

    Rank-independent quantum estimators achieve Θ(1/ε) queries for operator-norm (and trace) distance when one state is pure, and Õ(1/ε^{3/2}) queries for general states, proving BQP-completeness.

  2. Realizing Unitary $k$-designs with a Single Quench

    quant-ph 2025-11 conditional novelty 7.0 of 10

    A single quench between two independent random Hamiltonians at the Thouless time generates unitary k-designs.

  3. Analytic R\'enyi Entropy Bounds for Device-Independent Cryptography

    quant-ph 2025-07 conditional novelty 7.0 of 10

    Exact analytic Rényi entropy rate functions for the CHSH inequality tighten finite-size DIQKD key rates and reduce the minimum number of rounds by nearly a factor of three.
