Dynamics of Work Extraction in Multipartite Atomic Systems: Role of Correlations and Relative Entropy
We investigate the dynamics of quantum ergotropy in a multipartite system of two-level atoms interacting with a quantized field.ProtocolMatch: Protocol-Dependent Model Selection for Scientific Dynamics Forecasting
Scientific dynamics forecasting is often framed as an architecture choice, although deployment is also determined by observed history, rollout feedback, compute budget, physical objective, and test…An Explicit Counterexample to Tsirelson's Problem via a Linear System Game
We construct an explicit binary linear system game that separates $C_{qa}$, the closure of the set of finite dimensional quantum correlations, from $C_{qc}$, the set of commuting operator…Benchmarking Modular Optimization Strategies for Parameterized Quantum Circuits
Training parameterized quantum circuits requires balancing optimization progress with limited evaluation budgets and the statistical uncertainty of near-term quantum hardware.QuSema: Detecting Silent Bugs in Quantum Libraries via Quantum-knowledge-enhanced Agents
Quantum libraries are now critical infrastructure for quantum algorithm development, yet their correctness remains difficult to test.Numerically exact simulation of open quantum networks with strong system-bath couplings using tensor network path integrals
Non-Markovian open quantum networks are among the most challenging problems in quantum theory, as they suffer from both, the exponentially scaling many-body state space as well as long memory times…Gaussian Scrooge Ensemble from Deep Thermalization in Free-Fermions
Deep thermalization indicates the emergence of universal ensembles of pure states in a subsystem after measuring its environment.Sub-shot-noise mid-infrared photothermal measurements using twin beams
Mid-infrared photothermal (MIP) measurement probes refractive-index changes induced by mid-infrared (MIR) absorption using visible or near-infrared light and has recently emerged as a powerful…Physics-Aligned Electronic Ground-State Learning Improves Generalization
Machine-learned interatomic potentials (MLIPs) excel at in-distribution tasks, accelerating drug and material development, yet they struggle to generalize out-of-distribution.Binary Optimization of Measurement Groupings for Quantum Energy Estimation
Repeated measurements can dominate the resources required for quantum energy estimation, making the choice of which Pauli observables to measure together a central optimization problem for…Measurement-Efficient Differentiable Quantum Architecture Search for Combinatorial Optimization
Differentiable quantum architecture search (DQAS) is a promising framework for the automated design of quantum circuits, particularly for variational quantum optimization algorithms.Quantum simulation of the Heisenberg XXZ model on a Rydberg atom array
A major application of analog quantum hardware is quantum simulation, where a system evolves over time according to a given Hamiltonian.CV-QKD with noisy coherent states and realistic displacement receivers
Near-optimal binary coherent state discrimination can be achieved by performing a displacement operation followed by photon detection.Design-Time Conformance Checking for Pulse-Level Quantum Control
A pulse-level quantum control program is written against a device whose limits are recorded, if at all, in vendor documentation and source code.Dynamically protected erasure qubit via low-frequency charge driving
Dynamical protection via strong driving can enable resilient quantum processing on imperfect physical hardware.Optimized discrete Wigner representations and non-stabilizerness in qubit systems
The apparent absence of a stabilizer-specific phase-space description for qubit systems is not fundamental, but arises from fixing a state-independent discrete Wigner map.Standard estimators cannot represent fault-tolerant workloads at measured error rates: evaluated, evidence-based uncertainty for quantum resource estimation
Estimates of the quantum resources needed to run fault-tolerant algorithms are almost always reported as single numbers, even though they rest on uncertain hardware parameters and on cost models…Black hole radial geometry from a quantum spin chain
We show that the radial differential equation for a scalar field in an anti-de Sitter black brane background can be encoded in an exactly solvable semi-infinite spin chain independent of…Efficient Estimation of Logical Sensitivities Through Fault-Counting
Quantum error-correcting circuits are affected by multiple physical noise mechanisms, whose contributions to logical failure must be understood to evaluate code performance and guide improvements in…Spin Chain with Continuous Exponential Symmetry: Topological Phase and Beyond
We study symmetric gapped ground states of one-dimensional spin $S$ chains with a continuous exponential symmetry $U(1)\rtimes\mathbb Z_2$ with integer base $q$, where the U(1) charge has a…
