Metal‐Organic Open‐Framework Molecular Magnet Based on Vanadium Hexacyanoferrate Prussian Blue Analogs as Cathode Material for Advanced Potassium Ion Aqueous Battery

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
An aqueous potassium‐ion battery using vanadium hexacyanoferrate (VHCF) as the cathode and graphite as the anode is presented. During charge/discharge, K+ ions shuttle between electrodes through the electrolyte, enabling energy storage. The VHCF material demonstrates high capacity (≈121 mAh g−1), fast kinetics, and eco‐friendliness, making it a ...

Quantum Interference Effect in Saturated Systems: Effect of Anchoring Group Position on Conductance of Bipiperidines and their in‐situ Derived Dithiocarbamates

open access: yesAngewandte Chemie, EarlyView.
This study illustrates distinct quantum interference effect in saturated systems as compared to their unsaturated counterparts and the origin of multiple conductance features observed in single molecule conductance experiments of different isomers of bipiperdine and their in‐situ generated dithiocarbamates.

Energy‐Efficient Knapsack Optimization Using Probabilistic Memristor Crossbars

open access: yesAdvanced Intelligent Systems, EarlyView.
The knapsack problem, a nondeterministic polynomial‐time (NP)‐hard combinatorial optimization problem, is solved energy‐efficiently. This work presents an algorithm‐hardware co‐design and implementation for practical (non‐ideal) NP‐hard problems with destabilizing self‐feedback (non‐zero diagonal) and non‐binary Hamiltonian representations under analog

Spin Interactions in Supramolecular Assemblies of Porphyrin Oligomer Radical Anions

open access: yesAngewandte Chemie, EarlyView.
Double‐strand porphyrin ladder complexes offer an excellent way to hold two spin centers in a well‐defined structure. Nutation experiments on the dianion of such complexes confirm the presence of doublet and triplet species. Spin dynamics simulations show that the emergence of these higher multiplicities can be fully accounted for by considering the ...

Is Computing with Light All You Need? A Perspective on Codesign for Optical Artificial Intelligence and Scientific Computing

open access: yesAdvanced Intelligent Systems, EarlyView.
This perspective article considers what computations optical computing can and should enable. Focusing upon free‐space optical computing, it argues that a codesign approach whereby materials, devices, architectures, and algorithms are simultaneously optimized is needed.

Nucleic Acid‐Based Molecular Machines for Biological Applications

open access: yesAdvanced NanoBiomed Research, EarlyView.
Molecular machines are devices assembled from molecules with specific functions. In this review, the development of DNA nanostructures, which are then assembled into molecular machines, is summarized. Their classification and biological applications, such as biosensing, targeted therapy, and molecular circuits are introduced.

Signatures of the Correlated‐Hopping Interaction in Non‐Linear Transport Through a Quantum Dot

open access: yesAnnalen der Physik, EarlyView.
Non‐linear thermoelectric transport through a quantum dot is studied, in order to elucidate the signatures of so‐called correlated hopping. The line shapes of the differential conductance and the Seebeck coefficient as functions of gate voltage are clear indicators of this important interaction term.

Benefits of Open Quantum Systems for Quantum Machine Learning

open access: yesAdvanced Quantum Technologies, EarlyView., 2023
Quantum machine learning (QML), poised to transform data processing, faces challenges from environmental noise and dissipation. While traditional efforts seek to combat these hindrances, this perspective proposes harnessing them for potential advantages. Surprisingly, under certain conditions, noise and dissipation can benefit QML.

Comparison of Two Optimization Methods for a Rydberg Quantum Gate

open access: yesAnnalen der Physik, EarlyView.
Quantum gates are the backbone of digital quantum computing. A shortcut‐to‐adiabaticity is compared with a numerically optimized protocol for a Rydberg gate. The counterdiabatic method offers an analytical framework for accelerating high‐fidelity gates by mimicking the time evolution of a counterdiabatic Hamiltonian using fast‐oscillating fields.
