Finding Gaussian Structure in Bosonic States
We study agnostic tomography of pure bosonic Gaussian states: given copies of an arbitrary $n$-mode bosonic state $ρ$, the goal is to output a pure Gaussian state whose infidelity with $ρ$ is at…Energy-constrained two-way capacities of pure-loss and quantum-limited amplifier channels
We determine the two-way quantum, entanglement-distribution, private, and secret-key capacities of the pure-loss bosonic channel under an unconditional mean transmitted-photon-number constraint.Quantum information processing under maximal distance measures
The measures of distance frequently used in quantum information, such as trace distance or fidelity-based purified distance, are the smallest extensions of the corresponding distance measures in…Posh Parking Spaces
Let $W$ be an irreducible complex reflection group with reflection representation $V$.The quantum-classical bipartite universe and the logical emergence of $\hbar$ from classical temporality
We present a foundational reinterpretation of quantum dynamics based on the standard von Neumann formalism, positing a structural logical bipartition between a classical observational environment…Error-Transparent Code Switching Between Permutation-Invariant Codes with Transversal Clifford and Icosahedral Gates
Code switching moves an encoded qubit between two codes whose transversal gates together are universal, but the switching operation itself is usually not transversal and can spread a single fault…Cups and Gates II: Operads, twists, and addressable intra-code gates
In Part I, we introduced a general framework for constructing logical gates in quantum CSS codes from cohomology invariants, focusing on cup products and their generalizations from topological to…Walk/Zeta correspondence for quantum walks on path graphs: a pre-geometric structure implied by a generalized reflection principle
We establish a local Konno-Sato correspondence for reflected random and Szegedy walks on a finite path graph.Frame-dependent coherence of Gaussian quantum states
A Hilbert space is usually described using an orthonormal basis, but a more general description can be defined using a tight frame.Exact Finite-Channel Schur Moments of the Wigner-Smith Matrix with a Tunnel Barrier
We consider the Wigner--Smith time-delay matrix of a chaotic cavity with broken time-reversal symmetry, a finite number $M$ of equivalent open channels, and a uniform tunnel barrier of reflection…Stabilizer codes over general phase spaces
We develop a theory of stabilizer codes whose stabilizer groups consist of commuting qudit Paulis, oscillator displacements, and/or planar-rotor displacements.Majorana bilinears, compact modular seeds and the approach to the Tsirelson bound
In this work we study the Bell-CHSH inequality in the vacuum of the free massive Majorana field in $1+1$ dimensions, taking as the dichotomic observables of the two parties even bilinears of smeared…On some concepts of convergence and their connections
The notions of classical two-scale convergence and the periodic unfolding method, which both rely on an additional scale for the representation of periodic micro-oscillations, are in this paper…S$^{2}$-PINN: Stochastic Separable Physics-Informed Neural Networks
Uncertainty quantification (UQ) for random partial differential equations (PDEs) is ubiquitous in computational science and engineering.Strict non-tightness of the level-3 quantum bootstrap for a natural three-dimensional Hamiltonian, at an excited level
For the coupled three-dimensional double well $H=\tfrac12|p|^2+2\sum_i(q_i^2-1)^2-\sum_{i<j}q_i^2q_j^2$ we exhibit, at the first excited energy level (and also at the ground state), a linear…Parity-Time Symmetry of Plasma Waves
The susceptibility tensor of a homogeneous collisionless magnetized plasma possesses parity-time (PT) symmetry.Geometric Aspects of Entanglement
Quantum entanglement is a fundamental resource in quantum information theory, yet its general characterization and quantification remain challenging, especially in multipartite systems.Discriminating Lindbladian Dynamics
The fundamental task of quantum hypothesis testing, which consists in discriminating quantum objects, has been extensively studied for quantum states and channels.Modified logarithmic Sobolev inequality for 1D non-commuting Hamiltonians
Given a finite-range, non-commuting Hamiltonian on a 1D chain of finite spins, we prove a modified logarithmic Sobolev inequality with constant $Ω(1/\log n)$ for the heat-bath dynamics, a…Realizing Braided Fusion 2-Categories as (3+1)D Mixed-State Topological Orders
We construct large families of mixed-state topological orders in (3+1)D, including intrinsically mixed-state topological orders.
