An \textit{ab initio} based compact analytical formula for inelastic x-ray scattering from spatially localized excitons
In this contribution we provide a compact model for the description of inelastic x-ray scattering of spatially localized excitons.When Equivalent Quantum Circuits Lose Synthesis Choices
Quantum compilers synthesize high-level operations, such as the quantum Fourier transform and multi-controlled X gates, into gate-level circuits.Two superconducting pairing models with a Kitaev spin-liquid glue: microscopic kernel and parity alternation on odd-fold bond stars
We construct two superconducting pairing models on doped Kitaev honeycomb, whose microscopic kernels are derived rather than assumed.What Does It Cost to Simulate a Quantum Sentence Classifier? An Energy and Compute Perspective on Near-Term QNLP
Near-term quantum natural language processing (QNLP) experiments often run on classical simulators, so simulator cost is part of the field's practical compute burden, yet accuracy tables do not show…The superb supersinglet
Multipartite systems of high-dimensional particles can host forms of quantum entanglement inaccessible to qubit systems.A robust framework for the comprehensive characterisation of parametric down-conversion sources
Reliable verification of squeezed-light sources is essential for photonic quantum technologies.Improved Adaptive Estimation of Quantum Partition Functions with Heisenberg Scaling
We give quantum algorithms that estimate the log partition function of an $n$-qubit quantum Hamiltonian to additive error $ε$ with Heisenberg scaling, while minimizing calls to thermal-state…Casimir force screening by a quantum Boltzmann plasma
We develop a finite-temperature field-theoretical description of the Casimir interaction between two perfectly conducting boundaries with the intervening gap filled by a two-component quantum…Interferometric braiding of non-Abelian anyons
The manipulation of non-Abelian anyons is a foundational ingredient for topological quantum computing and underlies topologically protected quantum memories.Spatial delocalization of cold oscillators in hollow-core fibers
Trapped particles in hollow-core fibers enable long-range sensing, though advanced control of their in-fiber motion, such as multimodal cooling and squeezing, remains challenging.Black Hole Horizon Fluctuations from Unruh Quantum Noise
The mean Hawking flux does not determine how quantum stress fluctuations perturb a black-hole geometry.Unitary RQL Equals RQL
Intermediate measurements let quantum computations discard information and reuse their workspace.Probing Quantum Anomalous Hall Transport Under Microwave Irradiation Using a Topological Circulator
Edge magnetoplasmons (EMPs) provide a platform for probing chiral charge dynamics and nonreciprocal microwave transport in topological quantum materials.High-Fidelity Remote Graph State Preparation for Blind Quantum Computation
Measurement-based quantum computation (MBQC) relies on entangled graph states, yet existing remote state preparation (RSP) protocols prepare only separable states, requiring subsequent entangling…Suppressing Frequency Collisions in a Quantum Processor
Frequency crowding, the close spacing of qubit transitions, limits superconducting quantum processors through crosstalk, leakage, and spectator dependent errors.Adiabatic tracking and optimal schedules for classical and quantum Gibbs-state preparation
We develop a discrete adiabatic framework for Gibbs-state preparation in classical and quantum optimisation algorithms.Two-Sided Bounds on Ground State Properties in Lattice Gauge Theories
Gauge theories describe fundamental interactions in the standard model of particle physics and build effective theories in condensed matter physics.Electro-Optical Metalens for Near-Surface Cooling of a Levitated Particle
Advanced levitation optomechanics in the quantum regime requires sophisticated quantumengineered protocols operating at shorter length and time scales, demanding an increasing control over both…Robust subspace designs and the power of a unique small quantum witness
The concept of subspace designs was introduced by Guruswami and Xing (STOC'13), and explicit constructions were given by Guruswami and Kopparty (FOCS'13).Quantum Leakage from Shamir Sharing with Correlated Resources
We study leakage from Shamir secret sharing when each device uses its share to produce one qubit from an initial quantum resource independent of the secret and sharing randomness.
