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.

Thermoelectric Processes of Quantum Normal‐Superconductor Interfaces

open access: yesAnnalen der Physik, EarlyView.
Recent advances on using mesoscopic normal‐superconductor junctions for the thermoelectric effect is reviewed. A theoretical framework is presented for multiterminal configurations exploiting properties characterised by the interplay of the system reduced dimensionality and superconducting correlations.

Critical System Size for the Recovery of Topological Zero Modes in Finite Non‐Hermitian Systems

open access: yesAnnalen der Physik, EarlyView.
A generalized non‐Hermitian SSH model on a topolectrical circuit reveals size‐dependent topological zero modes. Non‐Hermiticity enables exact zero‐admittance edge states at a critical system size, tunable via asymmetric coupling and gain/loss. Large impedance peaks signal these modes, offering insights for designing robust topological devices with ...

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.
