This study numerically demonstrates that vertically oriented hollow gold nanocavities coupled to monolayer MoS2 can spectrally tune and significantly enhance A and B excitonic emission through geometry-controlled plasmon resonance, achieving up to 144-fold photoluminescence increases and enabling precise engineering of excitonic peak ratios for advanced valleytronic and sensing applications.
This paper demonstrates that light scattering from pairs of point-like dipoles exhibits exact resonances when the dipoles violate the optical theorem (indicating nonequilibrium or active conditions), leading to potentially infinite scattering amplitudes, while similar but finite resonances in equilibrium systems can still yield significant amplification factors.
This paper presents an accessible, Bloch-space-based explanation for why the Born rule is unavoidable in quantum systems of dimension three and higher, while clarifying why non-Born probability rules remain possible for two-dimensional qubits.
The paper demonstrates that a specific promise problem distinguishing between a fixed permutation and a phase-modified permutation on an -qubit system can be solved with certainty using a single query and a measurement of only one qubit, without requiring ancilla qubits.
This paper derives closed-form expressions for the entanglement fidelity of various standard quantum noise models using Schumacher's Kraus-operator approach, analyzing how channel and source parameters influence the preservation of quantum correlations for general input states.
This paper introduces a Lindbladian learning method that combines maximum-likelihood estimation on transient Pauli measurements with a neural differential equation framework to robustly infer open-system quantum dynamics, including dissipative mechanisms, across various hardware platforms and noise conditions with high efficiency.
This paper proposes and analyzes a gate reflectometry-based experimental procedure that enables the simultaneous discrimination of all four computational basis states of a pair of spin qubits in silicon double quantum dots, offering a pathway to reduce readout overhead in scalable quantum computers.
This paper proposes a unified theoretical framework that extends the action-angle formalism to the Helmholtz-Schrödinger equation using Hardy space to resolve phase paradoxes via a "Dirac sea" of negative energy states, thereby explaining Talbot revivals and fractal interference patterns in multimode waveguides with anharmonic refractive indices.
This paper demonstrates that on current noisy intermediate-scale quantum (NISQ) devices, second-order symmetric Trotterization fails to outperform first-order methods in simulating transverse-field Ising model dynamics due to hardware errors dominating over the theoretical Trotter error, suggesting that higher-order decompositions should be used cautiously in early-stage quantum simulations.
This paper proposes an alternative quantum information advantage protocol based on parallel-repeated CHSH games that utilizes an information-based memory measure, offering an efficient verifier and a more noise-robust, efficient quantum prover compared to the recent experimental demonstration by Kretschmer et al.
This paper proposes a unified geometric framework that visualizes two- and three-qubit pure states by explicitly separating local degrees of freedom, represented via Bloch spheres, from nonlocal entanglement degrees of freedom, captured through complex concurrences, to provide an intuitive and complete coordinate representation of quantum states.
The paper presents Lattice (LAT), a post-quantum peer-to-peer electronic cash system designed as a settlement layer for the quantum era by integrating RandomX CPU-only proof-of-work, LWMA-1 difficulty adjustment, and NIST-standard ML-DSA-44 lattice-based digital signatures with a specific emission schedule and block weight scaling mechanism.
This paper derives closed-form analytic expressions for leading-order relativistic corrections to the wave-packet dynamics and uncertainty relations of a quantum harmonic oscillator, demonstrating that these effects become experimentally verifiable (reaching 0.1% to 1% deviation) for electron wave packets confined within keV-scale energies.
This paper introduces a classically driven hybrid quantum algorithm that reduces measurement overhead in electronic-structure simulations by iteratively transforming the Hamiltonian toward a diagonal form using sequential Givens rotations determined via classical low-dimensional block analysis, thereby minimizing quantum circuit depth and measurement requirements.
This paper proposes and experimentally outlines a practical protocol for implementing arbitrary nonlocal controlled-unitary gates between distant nodes using indefinite causal order and entanglement, which reduces circuit complexity and enhances flexibility compared to conventional fixed causal-order methods.
This paper proposes a physics-informed neural network method (PINN-DQME) to efficiently simulate non-Markovian open quantum dynamics by circumventing the time-dependent variational principle, demonstrating high accuracy for weak non-Markovian regimes at high temperatures while facing error accumulation challenges in strongly non-Markovian low-temperature scenarios.
The paper proposes a bipartite quantum key distribution protocol that leverages indefinite causal order, specifically utilizing a process matrix resource to achieve an 85.35% raw bit-matching probability between Alice and Bob, which is sufficient for standard error correction and practical implementation.

This paper establishes a realistic, end-to-end framework for quantum sensing under finite resources, demonstrating through Bayesian analysis that apparent Heisenberg-like scaling in strategies like NOON states often stems from prior constraints rather than genuine measurement information, thereby clarifying the specific conditions under which nonclassical resources provide true metrological advantages.
This review surveys theoretical and experimental advances in the physics of trions within two-dimensional monolayers, highlighting their enhanced binding energies due to reduced screening and confinement, the impact of environmental and external field factors, and their connections to broader many-body phenomena.
