Research Summary

Anran Jin works at the interface of quantum information, secure quantum communication, and quantum many-body diagnostics. Her recent papers use information-theoretic tools in two rather different settings: practical continuous-variable and phase-matching quantum key distribution, and strange-correlator or entropy-based probes of critical lattice models. The resulting research profile is centered on how robust information can be extracted from noisy quantum systems, whether the goal is cryptographic security or the identification of hidden critical and topological structure.
