Finite Quantum Engineering Thermodynamics
A useful thermodynamic model predicts what a device will do without tracking its full microscopic state.Construction of isoscattering non-isospectral quantum graphs using the concept of a germ graph
The recently developed concept of germ graphs (P.Holographic Krylov complexity in confining backgrounds: particle, string, and frames
We investigate holographic Krylov complexity in bottom-up holographic QCD models describing the confined phase, using the recently proposed correspondence between the growth rate of Krylov…Correlation-Based Measurement of Entanglement in Rank-2 Mixed States
We study correlation-based entanglement evaluation in rank-2 mixed states of two- and multi-qubit systems.Decoder- and Noise-Aware Optimization Framework for Clifford-Deformed Quantum Error-Correcting Codes
Practical fault-tolerant quantum computing requires qubit-efficient quantum error correction (QEC).Entanglement Catalysis Beyond the Asymptotic Rate
Quantum entanglement is a fundamental resource in quantum information science, commonly consumed to perform tasks like quantum teleportation and quantum key distribution.Genuine multipartite nonlocality detection in graph states
Experimental detection of multipartite Bell nonlocality faces many challenges.Encoding Matters: A Qubit-Efficient Reformulation for Quantum Resilient Routing
Qubits are powerful computational resources because each additional qubit doubles the size of the accessible state space.Operational signatures of exceptional quantum channels
Exceptional points (EPs) are usually introduced as defective degeneracies of non-Hermitian Hamiltonians and, in fully open quantum dynamics, of Liouvillian generators.Finite-Size Limits of Adaptive Pauli Prediction
Can quantum data reliably answer questions chosen from earlier results?Judd-Ofelt analysis and coherent spectroscopy of europium-based molecular complexes for quantum information applications
Rare-earth-ion based molecular crystals are emerging as a promising platform for quantum information applications, combining long optical coherence times with the chemical tunability of coordination…QTN-RQNN: Quantum Tensor Network-Based Recurrent Quantum Neural Network
Resource constraints and imperfect quantum operations remain major challenges for quantum machine learning (QML) on noisy intermediate-scale quantum (NISQ) devices, particularly for fault-diagnosis…Dynamical Lie Algebras for Fixed-Gate Quantum Ansätze
Parameterized Quantum Circuits have emerged as a central framework for variational quantum algorithms in the NISQ regime, with major applications in quantum simulation, combinatorial optimization…Locality-Preparation Time Tradeoffs in Dissipative Quantum Systems
Dissipative state preparation engineers quantum many-body states as steady states of an open-system dynamics.Replica Transition at Measurement-Altered Ising Criticality
Performing measurements on gapless quantum ground states can give rise to new universal phenomena, whose origins remain poorly understood even for the paradigmatic Ising critical point.Diversity-Aware Ensemble of Quantum-Classical Models via Combinatorial Fusion
Variational quantum circuits (VQCs) are highly sensitive to circuit architecture, yet most quantum machine learning pipelines select a single best design and discard the remaining candidates.QTestBench: A Test Framework for Evaluating LLM-Generated Quantum Code
Large language models (LLMs) have shown strong results in classical code generation and are increasingly used to write the unit tests that safeguard that code.A Hardware-Native Trapped-Ion Hybrid Qudit-Oscillator Instruction Set
Scaling trapped-ion processors by adding ions remains challenging.Enhanced analogue quantum computation with a logically-encoded XX gadget
The introduction of two-body XX interactions has been shown to improve the performance of quantum annealing in solving certain combinatorial optimisation problems and would enable the simulation of…No advantage from classical assistance for energy-constrained bosonic dephasing channels
We prove that four capacities of single-mode bosonic dephasing channels coincide under an average photon-number constraint: the unassisted quantum capacity, the unassisted private capacity, the…
