One-time memory from isolated Majorana islands
New Journal of Physics, 2022 A one-time memory (OTM) stores two bits such that either bit can be retrieved, but not both. One-time memories have been shown to allow for secure classical and quantum computations.

Temporal Dynamics Makes Memristive Physical Unclonable Functions More Secure and Ultra‐Lightweight
Advanced Electronic Materials, Volume 11, Issue 20, December 3, 2025.A temporal PUF (TPUF) is reported, using the randomness of temporal dynamics of memristors as an entropy source. By exploiting temporal complexity, significant reduction of hardware overhead is achieved in the TPUF, from otherwise at least hundreds‐of‐memristors‐scale crossbar arrays to only a pair of memristors.

Portable PGAS‐Based GPU‐Accelerated Branch‐And‐Bound Algorithms at Scale
Concurrency and Computation: Practice and Experience, Volume 37, Issue 25-26, 30 November 2025.ABSTRACT The Branch‐and‐Bound (B&B) technique plays a key role in solving many combinatorial optimization problems, enabling efficient problem‐solving and decision‐making in a wide range of applications. It incrementally constructs a tree by building candidates to the solutions and abandoning a candidate as soon as it determines that it cannot lead to ...
