Beyond Orbital Rotations: Correlation-Rank Limits and Clifford-Accessible Measurement, from Algebra and Global Optimization
Federico Zahariev, Vanda Glezakou·Jul 18, 2026
Algebra and RANGE global optimization play complementary, explicitly separated roles in identifying measurement structure beyond orbital rotations. In the fixed (1,1)-particle sector of two spatial orbitals per spin, algebra proves that one particle-...
Certified Optimal Measurement Reduction over Quantum Context Landscapes
Federico Zahariev, Vanda Glezakou·Jul 18, 2026
Quantum-measurement reduction contains two distinct global-optimization layers: a continuous problem of splitting an observable and allocating shots within a fixed measurement dictionary, and a nonconvex outer problem of designing the dictionary and ...
Experimental Nanoscale Thermodynamics
G. Andrew D. Briggs, Jörg Schmiedmayer·Jul 18, 2026
Modern fabrication techniques have allowed artificial systems to be constructed on a nanometre length scale. The ideas underlying thermodynamics, a field invented to describe large macroscopic systems, need to be modified to describe much smaller sys...
Universal Parent Hamiltonians for Adiabatic Warm Starts
Feng Qian, Peter J. Love·Jul 18, 2026
Computing the ground state properties of quantum systems is an important potential application of quantum computing. The success probability of quantum phase estimation approaches to ground state problems is proportional to the overlap of the input s...
Attosecond delay metrology beyond the photon coherence time with spectrally resolved Hong-Ou-Mandel interferometry
Yingwen Zhang, Kyle Jordan, Duncan England +3 more·Jul 18, 2026
Hong-Ou-Mandel (HOM) interferometry enables delay estimation at the quantum precision limit but is traditionally constrained to path differences within the coherence time of the interfering photons. Here, we demonstrate single-measurement path-delay ...
Geometric Qubits in Programmable Atomic Trimers
Julien Garaud, Antti J. Niemi·Jul 18, 2026
Motivated by programmable tweezer arrays, we develop an exactly solvable shape-space theory for near-equilateral atomic trimers. The Higgs oscillator on Kendall's shape sphere gives a nonresonant spectral lattice whose fixed-angular-momentum relative...
Removing inhomogeneous broadening in cross-relaxation spectra via hole burning
Fei Kong, Zhehua Huang, Zhengze Zhao +4 more·Jul 18, 2026
Quantum relaxometry based on nitrogen-vacancy (NV) centers in diamond is an easy-to-use technique that detects magnetic noise by measuring the longitudinal relaxation of NV centers. It is favored in chemical and biological applications due to the rob...
Robust PnP on a Neuromorphic Processor for Object Pose Estimation
Tam Ngoc-Bang Nguyen, Mohsi Jawaid, Tat-Jun Chin·Jul 18, 2026
Neuromorphic computing is gaining attention in robotic perception due to its higher energy efficiency. While neural network-based methods can more readily exploit the distributed and parallelized structure of neuromorphic computers, crafting neuromor...
Shortcuts to adiabaticity in five-level systems using counter-diabatic driving and time-rescaling optimization
Jiahui Zhang, Wenyuan Wang, Fuquan Dou·Jul 18, 2026
Shortcuts to adiabaticity (STA) is a common protocol to realize high-fidelity and robust quantum control in various quantum systems. To date, STA has been widely applied in two- and three-level systems, whereas designing feasible strategies to achiev...
Two-dimensional solitons in extended GPE models with Lee-Huang-Yang corrections
G. N. Koutsokostas, F. Bristy, E. C. Psychogiou +5 more·Jul 18, 2026
We investigate the existence and dynamics of two-dimensional solitary waves in a quantum droplet environment described by the extended Gross-Pitaevskii equation featuring logarithmic mean-field and Lee-Huang-Yang interactions. In the modulationally s...
Explainable Lightweight Compact Deep Models for Speech Emotion Recognition
Nelly Elsayed·Jul 18, 2026
Speech Emotion Recognition (SER) is an important component in a wide range of human-centered applications, including healthcare, customer service, and human-omputer interaction. In medical and decision-support settings, there is increasing interest i...
Identity-Paired Progressive Depth Training: When Trainability Persists Beyond Expressibility
Athanasios Hadjidimoulas, Tirthak Patel, Anastasios Kyrillidis·Jul 18, 2026
Variational Quantum Algorithms (VQAs) are a leading paradigm for near-term quantum computing, yet their training suffers from sensitivity to circuit depth, initialization, and landscape pathologies such as barren plateaus. We study \emph{progressive ...
SABLE: Minimalist Instruction-Level Authenticated Encryption for Constrained Confidential Computing
Hamid Noori, Carlton Shepherd·Jul 18, 2026
Conventional processor designs expose code and data as plaintext throughout execution, rendering them inherently vulnerable to attacks that recover intellectual property or modify security/safety checks. Instruction-level encryption (ILE) enables CPU...
Extending the Frontiers of QNLP Beyond English: Grammar-Sensitive Pipeline for Hindi Sentiment Classification Using Compositional Quantum Models
Gautami Sanjay Naik, Rishi Koushik Reddy Thippireddy, Naman Srivastava +4 more·Jul 18, 2026
Advancements in Natural Language Processing (NLP), whether on classical or quantum platforms, have predominantly focused on English due to its widespread use and abundant linguistic resources. Although English remains the most studied language in com...
Reliability Is Not Free in Universal Quantum Work Extraction
Shuai Zeng·Jul 18, 2026
Universal work extraction shows that input-state knowledge is unnecessary to attain the asymptotic free-energy rate. We ask whether this first-order universality extends to reliability, the exponential decay rate of extraction failure. In the work-ba...
Quantum Metrological Detection of the Unruh Effect with Optimized Accelerated Two-Level Atoms
Yao Jin·Jul 18, 2026
For a uniformly accelerated two-level probe atom, the acceleration-dependent factor is encoded in the atomic state during the atom-field evolution. If this factor can be estimated through a large number of measurements with an uncertainty smaller tha...

Sandeep Singh, G. K. Samanta·Jul 18, 2026
We present a projection-free method for mapping two-dimensional polarization distributions using Hong-Ou -Mandel (HOM) interference. Conventional polarization characterization techniques, such as Stokes polarimetry, rely on sequential intensity measu...
