Algorithmic Wave-Particle Duality: Pathfinding in Welded Trees is Hard
In the welded trees problem, an algorithm navigates a randomly labeled graph formed from two binary trees joined at their leaves through a "weld" of connecting edges.Rotated-Frame Determinant Discovery for Ground- and Excited-State Quantum Selected Configuration Interaction
Quantum Selected Configuration Interaction (QSCI) constructs a variational determinant space from measurements of a prepared electronic state, but finite-shot sampling can repeatedly observe…Norm Bounds on Sums of Positive Operators with Applications to Monogamy Games and Quantum Key Distribution
Bounding the acceptance probabilities of quantum measurements is a recurring task in quantum information theory.Optical angular momentum and pseudospin-orbit coupling in photonic graphene
We investigate the dynamics of structured laser beams carrying angular momentum (AM) as they undergo conical diffraction in photonic graphene.Magnetic Bloch eigenvalue problems in nonuniform periodic magnetic fields: a Fourier-finite difference approach
We study magnetic Bloch eigenvalue problems for two-dimensional magnetic Schrödinger operators with nonuniform periodic magnetic fields and periodic scalar potentials, and develop a hybrid…The Structure of Shared Classical Facts in Quantum Systems
Perfectly matching local outcomes need not constitute a nondisturbing shared classical record.Local information processing capacity: anatomy of computation in neuromorphic systems
Many neuromorphic systems possess rich internal computational structures shaped by their physical dynamics.Sample-based Quantum Diagonalization via Density Matrix Renormalization Group
We introduce SqDMRG, which combines sample-based quantum diagonalization (SQD) with the density matrix renormalization group (DMRG).Collectively pumped superradiant laser with coherence scaling beyond the standard quantum limit
For more than half a century, the standard quantum limit (SQL) was thought to limit the laser coherence $\mathfrak{C}$ -- the number of photons emitted from the laser into the beam in one coherence…Perturbation-Based Reconstruction of Depth-Resolved OCT Attenuation without Requiring a Fully Decayed Signal Tail
Depth-resolved attenuation in optical coherence tomography (OCT) can provide quantitative optical contrast beyond structural imaging.Quantum Key Exchange from Public Quantum Money
Two-message quantum key exchange (2QKE) cannot be realized in a statistically secure way, and therefore some computational assumptions are required.Quantum Computing for Entanglement Asymmetry and the Quantum Mpemba Effect in Field Theory
We construct a quantum measurement protocol for estimating the Rényi entanglement asymmetry, which quantifies symmetry breaking at the level of a subsystem and provides a probe of the quantum Mpemba…Spectroscopy-informed Deep Learning Searches for Photometric Little Red Dots in JWST Surveys
Little Red Dots (LRDs) are a population of compact, red sources discovered at high redshift with JWST that exhibit distinctive V-shaped spectral energy distributions (SEDs).Single-sided lens terahertz flat-top beam shaping in the Fresnel region
In this paper, a novel, to our knowledge, analytical approach is introduced for the design of a single-sided plano-convex lens (PCL) capable of terahertz (THz) flat-top beam shaping in the Fresnel…Millimeter-Wave Gaussian-to-Flat-Top Beam Shaping Using a Single-Curvature Lens: A Novel Approach
This paper presents a novel method for converting the divergent Gaussian intensity distribution of a millimeter-wave source into a uniform (flat-top) distribution using a single curved surface.Exact Transport-Information Correspondence for Distribution-Adaptive Discretization
Discretization of continuous probability distributions is an operation on the sample space, and the structure induced by this operation cannot generally be determined solely from information geometry.Shadow bootstrapping: Nearly minimal-setting pure-state tomography with shallow Clifford measurements
We present a pure-state tomography algorithm that uses a nearly minimal number of measurement settings while achieving optimal sample complexity with nonadaptive single-copy shallow Clifford…Classical Clifford+T Sampling without Computing Marginals
We introduce a new exact classical sampling algorithm for Clifford+T circuits, called T-by-T sampling.Ab Initio Accuracy Beyond the Cutoff: Distributed Message-Passing Equivariant Attention at Tens-of-Millions-of-Atom Scale
Molecular dynamics predicts molecular motion from atomic forces and trajectory integration.A Post-Quantum Interactive Hashing Theorem
Interactive hashing, introduced by Ostrovsky, Venkatesan, and Yung [OVY93], is a building block in many cryptographic protocols, including perfectly hiding commitments from one-way permutations…
