Crypto-RV: High-Efficiency FPGA-Based RISC-V Cryptographic Co-Processor for IoT Security
Anh Kiet Pham, V. T. Vo, V. Le +4 more·Feb 4, 2026
Cryptographic operations are critical for securing IoT, edge computing, and autonomous systems. However, current RISC-V platforms lack efficient hardware support for comprehensive cryptographic algorithm families and post-quantum cryptography. This p...
Data Verification is the Future of Quantum Computing Copilots
Junhao Song, Ziqian Bi, Xinliang Chia +2 more·Feb 3, 2026
Quantum program generation demands a level of precision that may not be compatible with the statistical reasoning carried out in the inference of large language models (LLMs). Hallucinations are mathematically inevitable and not addressable by scalin...
Correlation-Enabled Beatings in Two-Dimensional Electronic Spectroscopy
Sirui Chen, Dragomir Davidović·Feb 3, 2026
Long-lived beatings in two-dimensional electronic spectroscopy (2DES) remain difficult to interpret within standard excitonic open-system models, which typically assume factorized initialization and predict rapid coherence decay. We show that persist...
A Comparative Study of Digital Memristor-Based Processing-In-Memory from a Device and Reliability Perspective
Thomas Neuner, Henriette Padberg, Lior Kornblum +3 more·Feb 3, 2026
As data-intensive applications increasingly strain conventional computing systems, processing-in-memory (PIM) has emerged as a promising paradigm to alleviate the memory wall by minimizing data transfer between memory and processing units. This revie...
Approximate simulation of complex quantum circuits using sparse tensors
Benjamin N. Miller, Peter K. Elgee, Jason R. Pruitt +1 more·Feb 3, 2026
The study of quantum circuit simulation using classical computers is a key research topic that helps define the boundary of verifiable quantum advantage, solve quantum many-body problems, and inform development of quantum hardware and software. Tenso...
Contextuality from Single-State Ontological Models: An Information-Theoretic No-Go Theorem
Song-Ju Kim·Feb 3, 2026
Contextuality is a central feature of quantum theory, traditionally understood as the impossibility of reproducing quantum measurement statistics using noncontextual ontological models. We consider classical ontological models constrained to reuse a ...
Detailed, interpretable characterization of mid-circuit measurement on a transmon qubit
Piper C. Wysocki, Luke D. Burkhart, Madeline H. Morocco +12 more·Feb 3, 2026
Mid-circuit measurements (MCMs) are critical components of the quantum error correction protocols expected to enable utility-scale quantum computing. MCMs can be modeled by quantum instruments (a type of quantum operation or process), which can be ch...
A Unified Categorical Description of Quantum Hall Hierarchy and Anyon Superconductivity
Donghae Seo, Taegon Lee, Gil Young Cho·Feb 3, 2026
We present a unified category-theoretic framework for quantum Hall hierarchy constructions and anyon superconductivity based on modular tensor categories over $\mathrm{Rep}(\mathrm{U}(1))$ and $\mathrm{sRep}(\mathrm{U}(1)^f)$. Our approach explicitly...
Classical Benchmarks of a Symmetry-Adapted Variational Quantum Eigensolver for Real-Time Green's Functions in Dynamical Mean-Field Theory
Aadi Singh, Chakradhar Rangi, Ka-Ming Tam·Feb 3, 2026
We present a variational quantum eigensolver (VQE) approach for solving the Anderson Impurity Model (AIM) arising in Dynamical Mean-Field Theory (DMFT). Recognizing that the minimal two-site approximation often fails to resolve essential spectral fea...
Temperature driven false vacuum decay in coherently coupled Bose superfluids
Paniyanchatha Moolayil Sivasankar, Franco Dalfovo, Alessio Recati +1 more·Feb 3, 2026
The relaxation of a quantum field from a metastable state (false vacuum) to a stable one (true vacuum), also known as false vacuum decay, is a fundamental problem in quantum field theory and cosmology. We study this phenomenon using a two-dimensional...
Structures and proximity effects of inhomogeneous population-imbalanced Fermi gases with pairing interactions
Bishal Parajuli, Devin J. Gagnon, Chih-Chun Chien·Feb 3, 2026
By introducing spatially varying profiles of pairing interaction or spin polarization to quasi one-dimensional two-component atomic Fermi gases confined in box potentials, we analyze the ground state structures and properties when multiple phases coe...
Accelerating qubit reset through the Mpemba effect
Théo Lejeune, Miha Papič, John Goold +3 more·Feb 3, 2026
Passive qubit reset is a key primitive for quantum information processing, whereby qubits are initialized by allowing them to relax to their ground state through natural dissipation, without the need for active control or feedback. However, passive r...
Stochastic Thermodynamics of Quantum-Induced Stochastic Dynamics
Pedro V. Paraguassú·Feb 3, 2026
Quantum-Induced Stochastic Dynamics arises from the coupling between a classical system and a quantum environment. Unlike standard thermal reservoirs, this environment acts as a dynamic bath, capable of simultaneously exchanging heat and performing w...
Quantum speed limit time for bipartite entanglement in neutrino oscillations in matter with non-standard interactions
Abhishek Kumar Jha, Lekhashri Konwar, Rukmani Mohanta·Feb 3, 2026
In the three-flavor neutrino oscillation framework, we investigate the transition probabilities of an initial muon neutrino flavor state in the presence of non-standard interactions (NSIs) characterized by complex off-diagonal ($|ε_{αβ}|e^{iφ_{αβ}}$)...
