arXiv:2604.03726v1 Announce Type: new Abstract: High-fidelity quantum operations require the system dynamics to be strictly confined to the computational subspace. In practice, however, control fields…
arXiv:2604.03725v1 Announce Type: new Abstract: We extend the algebraic diversity (AD) framework from classical signal processing to quantum measurement theory. The central result -- the Quantum Algeb…
arXiv:2604.03662v1 Announce Type: new Abstract: We present a unified quantum-mechanical derivation of the Wallis formula from two solvable radial systems: the circular states of the three-dimensional …
arXiv:2604.03646v1 Announce Type: new Abstract: We propose a scheme to engineer the superradiant phase transition (SPT) in cavity magnonics by periodically modulating the frequency of the magnon mode.…
arXiv:2604.03633v1 Announce Type: new Abstract: Black hole spacetimes provide a natural setting for quantum systems in curved spacetime, where effects such as Hawking radiation arise from event horizo…
arXiv:2604.03607v1 Announce Type: new Abstract: We investigate absorption and scattering of structured light by atoms, treating the photon and the atomic center of mass as spatially localized wave pac…
arXiv:2604.03593v1 Announce Type: new Abstract: We study a discrete-time quantum walk in presence of a detector at $x_D$ initially. The detector here is repeatedly removed after a span of $t_R$, the r…
arXiv:2604.03577v1 Announce Type: new Abstract: High-dimensional quantum systems greatly outperform their two-dimensional counterparts in channel capacity, quantum complexity and efficiency, quantum c…
arXiv:2604.03576v1 Announce Type: new Abstract: Subradiance, a hallmark cooperative phenomenon in waveguide QED, is characterized by a universal power-law scaling of decay rates with system size and u…
arXiv:2604.03550v1 Announce Type: new Abstract: Monitored quantum circuits host a rich variety of exotic non-equilibrium phases. Among the most representative examples are measurement-induced phase tr…
arXiv:2604.03546v1 Announce Type: new Abstract: Quantum annealing is a quantum algorithm to solve combinatorial optimization problems. In the current quantum annealing devices, the dynamic range of th…
arXiv:2604.03495v1 Announce Type: new Abstract: A single photon in a superposition of $d$ modes naturally encode a $d$-dimensional quantum system, a so-called qudit. We show that such superpositions c…
arXiv:2604.03494v1 Announce Type: new Abstract: Periodic (Floquet) driving enables Hamiltonian engineering and nonequilibrium phases, but interacting systems eventually heat by absorbing energy from t…
arXiv:2604.03482v1 Announce Type: new Abstract: High-gain spontaneous parametric down-conversion (SPDC) produces bright squeezed vacuum with rich high-dimensional entanglement, but its output is inher…
arXiv:2604.03469v1 Announce Type: new Abstract: Reservoir computing promises a fast method for handling large amounts of temporal data. This hinges on constructing a good reservoir--a dynamical system…

arXiv:2604.03346v1 Announce Type: new Abstract: Partial differential equations (PDEs) play a crucial role in financial mathematics, particularly in portfolio optimization, and solving them using class…
One of the top-ranked law firms in the country confirmed today that it has suffered a data breach. Jones Day disclosed the breach after hackers known as Silent Ransom Group (SRG) posted the data to t…
arXiv:2604.03742v1 Announce Type: new Abstract: Effective evaluation of large language models (LLMs) remains a critical bottleneck, as conventional direct scoring often yields inconsistent and opaque …
