Buffer-Qubit-Based Quantum Circuit Allocation Method Against Crosstalk Attacks
Quantum Multi-Programming (QMP) enables the simultaneous execution of quantum circuits from multiple users on a single quantum chip in cloud quantum computing services.QUBO-Based Conformer Selection with Quantum-Classical Hybrid Optimization for Multiconformer Ligand Modeling
A ligand can adopt multiple conformations within the same binding site, and these conformations can interact differently with the surrounding protein.Algebraic criteria for complete relaxation in autonomous and periodically driven open quantum systems
We derive sufficient criteria that guarantee convergence of open quantum system dynamics to a unique long-time state independent of the initial conditions.Fast Template Matching for Quantum Circuits Using Hypergraph
Quantum circuit optimization is a key step toward the efficient execution of quantum algorithms.Evaluation of the quantum Fisher information for large systems via an ancilla
Quantum Fisher information (QFI) is a fundamental quantity in quantum information and quantum mechanics, and evaluating it in various physical systems has become an important research topic.Turning Quantum Compiler Configuration Selection Upside Down: A Top-Down Paradigm
Selecting an effective quantum compiler configuration requires coordinated decisions over both hardware targets and compiler settings, with the ultimate goal of improving circuit execution fidelity.Readout Dependent Parameter Identifiability of Quantum Kernels
A circuit parameter can change measured features without changing their projected Gaussian kernel.Alignment of the amplitudes of stored states for solving the associative memory problem using quantum annealing
The solution of combinatorial optimization problems by means of quantum annealing is based on the preparation of an equally superposition state.Geometry-controlled zeros of resonant Kelvin-wave conversion in four spatial dimensions
Geometry can suppress leading Kelvin-wave conversion even at exact momentum and frequency resonance.PQ-Vault: Provably Quantum-Safe Asset Custody for Unmodified Ethereum
A quantum computer could recover the key of any Ethereum account whose public key appears on chain.Low-field dephasing time of an optically polarized NV$^-$ spin bath beyond the P1 limit in diamond: a cluster-correlation-expansion and exact spin-bath study
Dense ensembles of nitrogen-vacancy (NV$^-$) centres in nitrogen-rich diamond dephase on the electron spins of the substitutional nitrogen (P1) centres.Boundary exceptional point driven chiral switch of topological edge states

We investigate spin-resolved momentum distributions and phase vortices in multiphoton electron-positron pair production within a modified two-level model.Adapted Fröhlich-Pizzo Model for Horizon-Induced Decoherence
The Fröhlich-Pizzo (FP) model is a quantum-mechanical model originally developed to describe the interaction between an atom and the electromagnetic field in the nonrelativistic limit $c\to\infty$.Quantum Simulation of Non-Markovian Open Quantum Systems via Low-Rank Kernel Compression and Coupling Dilution
We present an error-controlled framework for the quantum simulation of non-Markovian open-system dynamics in Gaussian environments.Convergence Analysis of the Quantum Blahut-Arimoto Algorithm and the Contraction Coefficient of Qubit Amplitude-Damping Channels
In this work, we investigate the convergence rate of the quantum Blahut-Arimoto (BA) algorithm proposed for computing the coherent information of less noisy quantum channels.The Lévy wave packet and fractional uncertainty relations
This work revisits the debate on fractional uncertainty relations that arose a decade ago and tries to settle it.Bounds on Attainable Rate Modulation in Fermi's Golden Rule
Controlling transition rates is a central objective across quantum optics, condensed-matter physics, and chemical physics, encompassing processes such as spontaneous emission, energy and charge…Photon Correlations Control Quantum Fisher Information in Coherent Multidimensional Spectroscopy
Coherent multidimensional spectroscopy probes interactions and dynamics of molecular systems through nonlinear optical signals.Quantum Belief Characterization: A Multi-Shot Notion of Equivalence
A recent formulation of quantum belief showed that quantum retrodiction depends not only on the reduced density operator of the system of interest, but also on correlations with a hidden reference…
