Single‐ and Two‐Mode Squeezing by Modulated Coupling to a Rabi Driven Qubit

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 3, March 2026.
A scheme for the generation of single‐ and two‐mode conditional‐squeezing of quantum harmonic oscillators by modulated coupling to a Rabi‐driven qubit is proposed. Simulations of a circuit QED system employing the scheme predict squeezing of more than 12dB and preparation of a superposition of 4dB squeezed states.

Symmetries of the garnier system and of the associated polynomial Hamiltonian system

open access: yesProceedings of the Japan Academy, Series A, Mathematical Sciences, 1990
For a completely integrable Pfaffian system \[ E(\theta):\;dx_ i=\sum^{n}_{j=1}G_{ij}(x,t,\theta)dt_ j,\quad G_{ij}\in {\mathbb{C}}(x,t),\quad i=1,...,m \] depending on parameters \(\theta \in {\mathbb{C}}^ N\), a symmetry for E(\(\theta\)) is a pair (S,l) of a birational transformation S: (x,t)\(\to (x',t')\) and an affine transformation l: \({\mathbb{

Digital Twin Simulations Toolbox of the Nitrogen‐Vacancy Center in Diamond

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 3, March 2026.
The Nitrogen‐vacancy (NV) center in diamond is a key platform within quantum technologies. This work introduces a Python based digital‐twin of the NV, where the spin dynamics of the system is simulated without relying on commonly used approximations, such as the adoption of rotating frame. The digital‐twin is validated through three different examples,

Ansatz-Free Hamiltonian Learning with Heisenberg-Limited Scaling

open access: yesPRX Quantum
Learning the unknown interactions that govern a quantum system is crucial for quantum information processing, device benchmarking, and quantum sensing. The problem, known as Hamiltonian learning, is well understood under the assumption that interactions ...

Decoding pH‐Driven Phase Transition of Lipid Nanoparticles

open access: yesSmall, Volume 22, Issue 14, 6 March 2026.
Ionizable aminolipids govern lipid nanoparticle (LNP) function through environment‐dependent protonation. Constant‐pH molecular dynamics reveal intrinsic, apparent, and surface pKa${\rm pK}_{\text{a}}$ values within LNP‐mimetic membranes, demonstrating that the LNP lipid environment induces a pronounced downward pKa${\rm pK}_{\text{a}}$ shift exceeding

Singular Isotonic Oscillator, Supersymmetry and Superintegrability

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2012
In the case of a one-dimensional nonsingular Hamiltonian H and a singular supersymmetric partner H_a, the Darboux and factorization relations of supersymmetric quantum mechanics can be only formal relations.

Methodological Frameworks for Computational Electrocatalysis: From Theory to Practice

open access: yesSmall Methods, Volume 10, Issue 5, 9 March 2026.
Computational modeling is widely used to investigate electrocatalytic reactions, yet accurately describing electrochemical interfaces remains challenging. This review outlines theoretical and computational strategies, based on density functional theory, to model reaction thermodynamics, solvation effects, applied bias, and kinetics.

Addressing ecological challenges from a quantum computing perspective

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 3, Page 632-649, March 2026.
Abstract With increased access to data and the advent of computers, the use of statistical tools and numerical simulations is becoming commonplace for ecologists. These approaches help improve our understanding of ecological phenomena and their underlying mechanisms in increasingly complex environments.

OccuGAMs: Non‐linear occupancy and abundance modelling with imperfect detection

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 3, Page 929-946, March 2026.
Abstract Hierarchical occupancy and abundance models (HOAMs) have become a leading approach for inferring wildlife population dynamics because they explicitly account for imperfect detection. HOAMs are suitable for sampling approaches that produce detection histories from repeated visits to the same sites, including direct observations (e.g. bird point

Atom cavity encoding for NP-complete problems

open access: yesQuantum Frontiers
We consider an atom-cavity system having long-range atomic interactions mediated by cavity modes. It has been shown that quantum simulations of spin models with this system can naturally be used to solve number partition problems.
