Exact Characterization of the Holevo Bound by a Quantum Fisher Information Family
The quantum Cramér-Rao bound constrains the precision of parameter estimation through the symmetric logarithmic derivative quantum Fisher information (SLD QFI).Spread Complexity for Local Operator Quenches with Conserved Momentum
We study a family of locally excited states in two-dimensional conformal field theories in different setups, defined on the plane, on the cylinder, or at finite temperature.Amplified Memory and Finite-Time Regularity in Driven Non-Hermitian Systems
We study the roles of broken spectra and exceptional points in finite-time driven non-Hermitian fermionic dynamics.Eigenoperator Entanglement Statistics in Local Lindbladians
Random matrix spectral statistics are widely used to diagnose quantum chaos in open systems, but whether chaotic eigenvalue correlations are accompanied by Haar-typical eigenoperators remains unclear.Observation of universal hierarchical relaxation in a quantum simulator
Autocorrelation functions play a key role in the theoretical characterization of the dynamical properties of interacting many-body quantum systems.Variational Multi-Gaussian Quantum Trajectories
We propose a variational framework for the efficient simulation of stochastic quantum dynamics in interacting bosonic systems.Deep thermalization and Hilbert space ergodicity
Recent advances in quantum simulation have enabled the discovery of novel forms of universality in quantum many-body dynamics.Informational and algebraic renormalization group
Renormalization group (RG) is a core concept in physics from statistical mechanics to quantum field theory, yet its schemes differ widely between field theory and many-body physics.Entanglement transitions in holographic conformal interfaces
We study entanglement transitions for pairs of disjoint intervals in two-dimensional holographic interface conformal field theories.A Mechanism for the Rényi Hierarchy of Decoherence-Induced Phase Transitions
Decoherence-induced phase transitions (DIPTs) are associated with singular changes in a quantum system's entanglement structure as the decoherence strength varies.Colored Weingarten Calculus for Block-Unitary Ensemble
Haar randomness is the standard null model for quantum typicality, scrambling, and random-matrix formulations of thermalization.Rényi Phase Transitions and Analytic Continuation to the von Neumann Entropy
Extracting operationally meaningful quantities such as von Neumann entropy and mutual information is central to characterizing many-body quantum systems, yet experiments and numerics often provide…A Novel $q$-Derivative Framework with Applications to $q$-Deformed Thermodynamics and Leakage Suppression in Superconducting Qubits
We propose a new $q$-derivative operator built directly from Jackson's $q$-number formulation, designed to preserve the structural properties of standard differential calculus while incorporating…Optimal low-rank compression of quantum dynamics
Local quantum interactions generate dynamics in an exponentially large Hilbert space, yet locality and entanglement restrict the information that can spread and accumulate.Fate of average symmetry-protected topological states under symmetry-preserving quantum operations
The fate of average symmetry-protected topological (ASPT) states based on the one-dimensional cluster state is investigated by using the Choi mapping, namely, the doubled Hilbert-space formalism.Classical Root Systems Reveal Defect-Junction Data in Stabilizer Renyi Entropy
Universal information extracted from a critical quantum state depends on how the state is probed.Rank-One Signal Recovery in Sparse Wishart Noise
We study the high-dimensional recovery of a signal vector $\mathbf{x}$ in the presence of sparse Wishart-like noise.Certifying fermionic Gaussian states (and a little more) with optimal precision dependence
Fermionic Gaussian states are the workhorse reference states for qubit-based quantum simulation of fermionic systems, yet existing certification protocols either proceed via fidelity estimation…Optimal limits on weak integrability breaking and protected thermal memory near qutrit exchange
Although integrability does not universally require a continuous one-site symmetry, we rigorously prove that every jointly analytic, regular Yang-Baxter deformation of the qutrit exchange…Nonequilibrium Phases of Repulsive Self-Attention: Chaos, Attention Condensation, and Emergent Locality
We study the nonequilibrium dynamics of a minimal recurrent transformer with $N$ normalized tokens, $Q=K=I$, and a negative value map $V=-I$.
