Two-Round Multi-Signatures from Okamoto Signatures

Mathematics, 2023
Multi-signatures (MS) are a special type of public-key signature (PKS) in which multiple signers participate cooperatively to generate a signature for a single message. Recently, applications that use an MS scheme to strengthen the security of blockchain

Unforgeable noise-tolerant quantum tokens [PDF]

Proceedings of the National Academy of Sciences, 2012
The realization of devices that harness the laws of quantum mechanics represents an exciting challenge at the interface of modern technology and fundamental science. An exemplary paragon of the power of such quantum primitives is the concept of “quantum money” [Wiesner S (1983) ACM SIGACT News 15:78–88].

Inorganic Photoluminescent Microparticles as Identifiers for the Sorting of Lithium‐Ion Battery Cathodes

ChemSusChem, Volume 19, Issue 8, 28 April 2026.
The growing demand for lithium‐ion batteries in the European Union contributes to critical raw material scarcity. This challenge can be addressed by establishing a circular economy, making use of highly efficient and economical recycling processes. The efficiency of these processes depends on high‐purity material streams and thus on the availability of

Noncovalent Interaction‐Mediated Space Charge Transition Facilitated Isolated Copper(I)‐Iodide Clusters: Enabling High‐Resolution X‐Ray Imaging and Dynamic Encryption

Aggregate, Volume 7, Issue 2, February 2026.
Solvent‐driven reversible “crystal to crystal” transformation of copper(I)‐iodine clusters with significant difference of luminescent color and quantum yields is reported. The differences before and after this transformation may be related to more efficient thermally activated delayed fluorescence (TADF) achieved by cluster 1 through space charge ...
