Quantum-echo Markov process for combinatorial optimization
We introduce a quantum-echo Markov process for combinatorial optimization.Eigenstate thermalization at the edge of the many-body spectrum
It is well-known that thermalization breaks down in presence of an extensive number of symmetries or conservation laws that are mutually compatible or commuting with each other.Engineered Dissipation for Thermal-State Tracking Across Quantum Criticality
Engineering dissipation has emerged as a powerful strategy for controlling quantum many-body dynamics, complementing purely coherent control for state preparation.A Dynamical Theory of LoRA in Continual Learning
Despite the widespread use of Low-Rank Adaptation (LoRA), little is known about its dynamics in continual learning and the mechanisms by which low-rank updates affect catastrophic forgetting.Square-root growth of operator entanglement in an integrable brickwork circuit
It is widely expected that the von Neumann entanglement of a local operator grows at most logarithmically in integrable many-body systems in infinite volume.Optimal Scaling of Unitary Design Formation in $U(1)$-Symmetric Random Circuits: A Bottleneck Slower than Charge Transport
Understanding randomness formation under conservation laws is important both for characterizing chaotic phenomena in isolated quantum systems and for symmetry-constrained quantum information…Optimal local recovery cannot alter critical orthogonality exponents in quantum spin environments
We prove a local amplitude-ratio bound for positive ground states and an explicit reverse comparison for fidelity under finite-region erasure.Exact Maximum Likelihood Decoding beyond Treewidth via Rank-Decomposition Dynamic Programming
Maximum-likelihood decoding provides an optimal decoding strategy for quantum error correction under stochastic Pauli noise.Fault Tolerant Quantum Phases of Matter
We introduce a classification of quantum phases of mixed states based on the ability to preserve and fault tolerantly transfer information.Predicting properties of Scrooge ensembles with high accuracy and low sample complexity
The Scrooge ensemble associated with a density matrix $ρ$ is the maximally random ensemble whose average density matrix is $ρ$.Many-body topology in parity-preserving tensor networks
Planar parity-preserving tensor networks (ppTNs) admit a fermionic formulation in which the Gaussian, efficiently contractible limit is deformed by local interactions.Pauli instability in arbitrary states: detecting magic in physical correlators
Measures of non-stabilizerness (``magic'') of a quantum evolution quantify how hard it is to simulate on a classical computer.Dissipation accelerates quantum and classical simulation of open-system dynamics
Simulating open quantum systems reveals how environmental coupling shapes relaxation, excitation transport, and the dynamics of quantum correlations.Efficient Calculation of Equilibrium Correlation Functions
A majority of measurable dynamic quantities of a physical system is described as an equilibrium correlation function of the form $G_{AB}(t-t') = \left $, where $t'$ represents the impact time and…Mixed-state phases induced by power-law quantum channels
Open quantum systems can exhibit inherently mixed quantum orders, such as strong-to-weak spontaneous symmetry breaking (SW-SSB), which have no analogue in pure states.Generative Modeling of Stochastic Dynamics for Long-Time Evolution
Exact stochastic equations for non-equilibrium dynamics are rarely accessible.Thermal entanglement transitions from strong $\textrm{SU}(2)$ symmetry
We study mixed-state entanglement in Gibbs states with strong $\mathrm{SU}(2)$ symmetry, focusing on locally interacting spin systems with ferromagnetic interactions.Crossover of Scaling Behaviors of Work Cumulants in a Driven Gaussian Field Theory
We derive the finite-temperature characteristic function of work (CFW) for a driven $O(N)$ Gaussian field theory and obtain closed-form expressions for all zero-temperature excess-work cumulants.Emergent Symmetries in Ensemble Averages
It is widely believed that there are no exact global symmetries in quantum gravity.Exact anomalous current fluctuations in the strong-anisotropy limit of the XXZ chain
We study spin-current fluctuations of the folded XXZ chain, which describes the strong-anisotropy limit of the XXZ chain.
