Pseudogap in a Fermi-Hubbard quantum simulator
Lev Haldar Kendrick, Anant Kale, Youqi Gang +4 more·Sep 22, 2025
Understanding doped Mott insulators is a fundamental goal in condensed matter physics, with relevance to cuprate superconductors and other quantum materials. The doped Hubbard model minimally describes such systems, and has explicated some of their c...
Efficient formulation of quantum network under amplitude damping noise: Highlighting benefits over its Pauli-twirled counterpart
Sudipta Mondal, Pritam Halder, Stav Haldar +1 more·Sep 22, 2025
At the heart of building a large-scale quantum internet lies the challenge of establishing long-distance entanglement using quantum repeaters, which mitigate direct transmission losses but introduce additional noise in the nodes via interactions with...
Exploring molecular supersolidity via exact and mean-field theories: single microwave shielding
Tiziano Arnone Cardinale, Thomas Bland, Stephanie M. Reimann·Sep 22, 2025
Ultracold polar molecules with microwave shielding provide a powerful platform for exploring quantum many-body physics with strong, anisotropic interactions. We develop an extended Gross-Pitaevskii framework for bosonic molecules under single microwa...
Optimal local basis truncation of lattice quantum many-body systems
Peter Majcen, Giovanni Cataldi, Pietro Silvi +1 more·Sep 22, 2025
We show how to optimally reduce the local Hilbert basis of lattice quantum many-body (QMB) Hamiltonians. The basis truncation exploits the most relevant eigenvalues of the estimated single-site reduced density matrix (RDM). It is accurate and numeric...
Fast and Accurate Decoder for the XZZX Code Using Simulated Annealing
Tatsuya Sakashita·Sep 22, 2025
The XZZX code is a variant of the surface code tailored to address biased noise in realistic quantum devices. We propose a simulated annealing (SA) decoder for the XZZX code. Our SA decoder is amenable to parallelization because its MCMC updates are ...
Functional Information in Quantum Darwinism: An Operational Measure of Objectivity
Arda Batin Tank·Sep 22, 2025
Quantum Darwinism explains the emergence of classical objectivity through the redundant encoding of pointer information in environmental fragments. However, existing diagnostics rely on arbitrary thresholds or structural assumptions that limit their ...
Enhanced fill probability estimates in institutional algorithmic bond trading using statistical learning algorithms with quantum computers
Axel Ciceri, Austin Cottrell, Joshua Freeland +13 more·Sep 22, 2025
The estimation of fill probabilities for trade orders represents a key ingredient in the optimization of algorithmic trading strategies. It is bound by the complex dynamics of financial markets with inherent uncertainties, and the limitations of mode...
Conditioning in Generative Quantum Denoising Diffusion Models
Daniel Quinn, Lorenzo Buffoni, Stefano Gherardini +1 more·Sep 22, 2025
Quantum denoising diffusion models have recently emerged as a powerful framework for generative quantum machine learning. In this work, we extend these models by introducing a conditioning mechanism that enables the generation of quantum states drawn...
QUT: A Unit Testing Framework for Quantum Subroutines
Mykhailo V. Klymenko, Thong Hoang, Hoa Nguyen +6 more·Sep 22, 2025
We present the architectural design and prototype implementation of QUT (Quantum Unit Testing), a framework for unit testing of quantum subroutines. The framework is developed with a focus on usability and simplicity, making the complex theoretical c...
Stabilizer Rényi Entropy and its Transition in the Coupled Sachdev-Ye-Kitaev Model
Pengfei Zhang, Shuyan Zhou, Ning Sun·Sep 22, 2025
Quantum entanglement and quantum magic are two distinct fundamental resources that enable quantum systems to exhibit complex phenomena beyond the capabilities of classical computer simulations. While quantum entanglement has been extensively used to ...
Quantum Simulation Programming via Typing
Liyi Li, Federico Zahariev, Chandeepa Dissanayake +3 more·Sep 22, 2025
Quantum simulations are designed to model quantum systems, and many compilation frameworks have been developed for executing such simulations on quantum computers. Most compilers leverage the capabilities of digital and analog quantum computers by re...
Efficient Measurement Error Mitigation with Subsystem-Balanced Pauli Twirling
Xiao-Yue Xu, Chen Ding, Wan-Su Bao·Sep 22, 2025
Measurement error mitigation (MEM) is essential for realizing reliable quantum computation. Model-free measurement error mitigation (MF-MEM) is an important class of MEM methods that employs Pauli twirling-typically with a random twirling set-to conv...
