Quantum Proof of Work with Parametrized Quantum Circuits

This paper proposes a Quantum Proof of Work (qPoW) for cryptocurrency mining and tests it on a 4-qubit quantum computer. Although the method works in principle, the quantum computation was currently significantly slower than a classical computer simulation. The authors project that a quantum advantage might be achievable with larger quantum computers (30+ qubits).

Kokkos 3: Programming Model Extensions for the Exascale Era

Kokkos 3 introduces new abstractions like hierarchical parallelism, advanced atomics, and graph constructs to improve performance portability for exascale systems. Benchmarks demonstrate the performance benefits of these features on both CPUs and GPUs, showcasing Kokkos's ability to adapt to diverse architectures.

Improvement of the Natural Self-Timed Circuit Tolerance to Short-Term Soft Errors

This paper explores the inherent tolerance of self-timed circuits to soft errors and suggests methods for enhancement. By treating anti-spacer states as valid spacers and improving pipeline indication, the authors theoretically demonstrate complete masking of soft errors in combinational circuits and increased tolerance in sequential circuits using DICE-like approaches.

Gap-enhanced Raman tags for physically unclonable anticounterfeiting labels

This research demonstrates the use of gap-enhanced Raman tags (GERTs) as a robust and highly-encoded physical unclonable function (PUF) for anticounterfeiting labels. By drop-casting different GERTs onto a substrate, a unique, random pattern is created which is nearly impossible to reproduce, offering a high level of security through 3D encoding based on the tags' location, spectral profile, and Raman intensity.
