Quantum spectral authentication: entity authentication and key derivation from a hidden eigenstate of a public unitary challenge

Abstract We introduce Quantum Spectral Authentication (QSA), a symmetric-key entity-authentication and key-derivation protocol in which a remote endpoint proves it still holds a hidden planted state, an eigenstate of the challenge it can prepare, without revealing it. Each round...

Efficient distinctiveness maximization in datasets assemblage: from homogeneous to heterogeneous datasets

Abstract We study the distinctiveness maximization problem for datasets assemblage: assembling a set of datasets from a repository that satisfies a user-specified target schema and query set under a budget constraint, while maximizing the number of distinct tuples. This problem i...

Identification of living (Rose Bengal)-stained benthic foraminifera using automated image recognition

Abstract. Living and fossil benthic foraminifera are widely used as bioindicators of ecosystem quality, but their analysis is time-consuming. With the help of artificial intelligence, models for the automatic identification of fossil planktonic foraminifera and, more recently, be...
