Out-of-time-ordered-correlators (OTOCs) have been suggested as a means to diagnose chaotic behavior in quantum mechanical systems. Recently, it was found that OTOCs display exponential growth for the inverted quantum harmonic oscillator, mirroring the ...

Quantum Theory of Surface Lattice Resonances
ABSTRACT The collective interactions of nanoparticles arranged in periodic structures give rise to high‐Q $Q$ in‐plane diffractive modes known as surface lattice resonances. Although these resonances and their broader implications have been extensively studied within the framework of classical electrodynamics and linear response theory, a quantum ...

Analyzing the Free States of one Quantum Resource Theory as Resource States of Another
The article investigates how free states in one quantum resource theory can become highly resourceful in another. It systematically studies multipartite entanglement, fermionic non‐Gaussianity, imaginarity, realness, spin coherence, Clifford non‐stabilizerness, Sn‐equivariance, and non‐uniform entanglement, combining rigorous analytical tools and ...

Control of Open Quantum Systems via Dynamical Invariants
Dynamical invariants are used to reverse‐engineer control fields for open quantum systems described by time‐dependent Lindblad master equations. By minimizing an analytic leakage functional, the protocol dynamically steers the state along an effectively decoherence‐free path without costly iterative propagation.

On the Aromaticity in Cyclic H‐Bonded Chains: Linking HOMIA Descriptor to Molecular Properties
ABSTRACT Aromaticity is a central concept in organic chemistry to explain the high stability of conjugated rings. This study extends this concept to cyclic hydrogen‐bonded (H‐bonded) chains by introducing a modified descriptor, the harmonic oscillator model of intermolecular aromaticity (HOMIA), to quantify aromaticity in cyclic H‐bonded chains of HCN,

Characterization of a quantum bus between two driven qubits
We investigate the use of driven qubits coupled to a harmonic oscillator to implement a sqrt[iSWAP] gate. By dressing the qubits through an external driving field, the qubits and the harmonic oscillator can be selectively coupled, allowing for the ...
