Generative Refinement Learning for Temporal Interpolation in Scientific Machine Learning
Computationally expensive simulations and real-world observations often provide data at a lower temporal resolution than downstream tasks require.Threshold Criteria for Bosonic and Fermionic Trimers on a Square Lattice: A Birman--Schwinger Comparison
We compare two three-particle lattice models on the square lattice at total quasimomentum zero: three identical bosons with attractive contact interactions, and a two-fermion plus one…Recovering classical gauge geometry from quantum master constraints
Exact normalizable solutions of quantum constraints form a symplectic submanifold of the space of rays, whereas classical first-class constraints define a surface on which the symplectic form is…Optimal quantum discrimination at Liouvillian exceptional points
Central to non-Hermitian sensing is the question of whether exceptional points (EPs) can make weak perturbations easier to detect.Defining 2-group symmetries on lattices and extracting their anomalies
Ordinary $0$-form symmetries $G$ can mix with $1$-form symmetries $Π_2$ to form a $2$-group $\mathcal{G}$.Fundamental limits on photonic state preparation from phase-space majorization
Preparing complex quantum states of light for quantum information processing tasks often proceeds by converting from simpler states via experimentally accessible operations.Exact Solution of the $(2+1)$-Dimensional Dunkl-Klein-Gordon Oscillator with a Uniform Magnetic Field in Non-Commutative Phase Space
We solve the Klein-Gordon oscillator in a non-commutative phase space, generalized using Dunkl derivatives, both with and without interaction with a uniform magnetic field.Stellar Representation of Gottesman Kitaev Preskill States on the Double Discrete Cylinder
Covariant integral quantization is developed on the double discrete cylinder phase space, with the torus as configuration space, and yields the Wigner distribution and the stellar representation.The Geometry of Quantum Teleportation in Phase Space
We formulate the standard quantum teleportation protocol within the framework of deformation quantization, employing the Stratonovich--Weyl (SW) correspondence and the associated star product on the…Spectral delocalization and central limit theorems for Fourier functionals of stationary Gaussian fields
We characterize Gaussian fluctuations of Fourier-Hermite functionals of stationary Gaussian fields on locally compact Abelian groups via spectral delocalization: conditional on the total spectral…Membership in the cone of quantum states over time is NP-hard
A state over time (stote) pairs a state $ρ$ with a channel $\mathcal{E}$ as the Hermitian, generally non-positive operator $(ρ\otimes\mathbf{1})\star J_\mathcal{E}$.Measurement-dependent reduction of open dynamics in the quantum phase estimation algorithm: the visible subspace and the damped Fejér kernel
For the quantum phase estimation (QPE) algorithm we study the minimal space of observables that is sufficient to predict the entire output distribution under open dynamics of the counting register.Geometric aspects of fault tolerance
We highlight three geometric aspects of fault tolerance.Competing coherence geometries in positive maps: positivity hierarchies, atomicity, and optimal entanglement witnesses
We introduce a family of positive maps on qudits whose Choi operators combine two competing coherence patterns: independent exchange couplings and a collective set of diagonal couplings.The $\varepsilon$-smoothed Entanglement of Formation and its relation to the Moreau-Yosida approximation
We describe a family of convex continuous functions $E_{F,\varepsilon}$, $\varepsilon\in(0,1]$, on the set of states of a bipartite quantum system (consisting of finite-dimensional or…Analytic Bootstrap Solution for Quantum Mechanics on a Circle
We solve the Schrödinger equation for a particle in the circle with a quantum mechanical bootstrap method.An algebraic characterisation of $n$-qubit pure-state invariants
We study the set of $n$-qubit pure quantum states.Quantum hydrodynamics from Nambu's unpublished fluid notes
We develop a quantum hydrodynamic theory based on Nambu's unpublished note \emph{A New Look at Fluid Dynamics}.Estimation of covariance matrix for Stokes-like measurement under phase-space deformation
We investigate the signatures of phase-space noncommutativity in an anisotropic oscillator and propose an optomechanical protocol to experimentally characterize it through Stokes-like measurements…On the uniqueness of translation-invariant ground states of the $S=1$ Heisenberg and $J$--$D$ antiferromagnetic chains
Using the analytic machinery and numerical inputs of OpenAI's proofs of the Haldane gap, we prove uniqueness of the translation-invariant ground state of the infinite $S=1$ Heisenberg…
