High-Level Fault-Tolerant Abstractions for Quantum-Gate Circuit Design and Synthesis: PQC and Topological Anyon Architectures (TQC) for Categorical Computations in SU(2)_3 TQFT and D-brane Stability
Vaidik A. Sharma, S. Bitragunta·Feb 5, 2026
We propose a dual-architecture quantum simulation framework for modeling morphisms and stability conditions in the bounded derived category $\mathbf{D}^b(\mathrm{Coh}(X))$, with applications to D-brane physics on K\"ahler and non-K\"ahler manifolds. ...
Dynamic Quantum Optimal Communication Topology Design for Consensus Control in Linear Multi-Agent Systems
Milad Hasanzadeh, Amin Kargarian·Feb 5, 2026
This paper proposes a quantum framework for the design of communication topologies in consensus-based multi-agent systems. The communication graph is selected online by solving a mixed-integer quadratic program (MIQP) that minimizes a cost combining ...
Toward Quantum-Safe Software Engineering: A Vision for Post-Quantum Cryptography Migration
Lei Zhang·Feb 5, 2026
The quantum threat to cybersecurity has accelerated the standardization of Post-Quantum Cryptography (PQC). Migrating legacy software to these quantum-safe algorithms is not a simple library swap, but a new software engineering challenge: existing vu...
Quantum computational imaging and sensing
Mohan Sarovar·Feb 4, 2026
We present a new framework for imaging and sensing based on utilizing a quantum computer to coherently process quantum information in an electromagnetic field. We describe the framework, its potential to provide improvements in imaging and sensing pe...
Photon entanglement-enhanced multidimensional spectroscopy of exciton correlations in photosynthetic aggregates
Arunangshu Debnath, Shaul Mukamel·Feb 4, 2026
Nonlinear spectroscopic techniques using entangled photon pairs can provide an opportunity to exploit non-classical correlations encoded in two-photon wavefunctions to manipulate two-exciton wavefunctions. We propose an entangled photon pair-enhanced...
Near-frustration-free electronic structure Hamiltonian representations and lower bound certificates
Nicholas C. Rubin, Guang Hao Low, A. Eugene DePrince·Feb 4, 2026
Hamiltonian representations based on the sum-of-squares (SOS) hierarchy provide rigorous lower bounds on ground-state energies and facilitate the design of efficient classical and quantum simulation algorithms. This work presents a unified framework ...
Learning fermionic linear optics with Heisenberg scaling and physical operations
Aria Christensen, Andrew Zhao·Feb 4, 2026
We revisit the problem of learning fermionic linear optics (FLO), also known as fermionic Gaussian unitaries. Given black-box query access to an unknown FLO, previous proposals required $\widetilde{\mathcal{O}}(n^5 / \varepsilon^2)$ queries, where $n...
Quantum Key Distribution with Imperfections: Recent Advances in Security Proofs
Patrick Andriolo, Esteban Vasquez, Elizabeth Agudelo +3 more·Feb 4, 2026
In contrast to classical cryptography, where the security of encoded messages typically relies on the inability of standard algorithms to overcome computational complexity assumptions, Quantum Key Distribution (QKD) can enable two spatially separated...
QuantumGS: Quantum Encoding Framework for Gaussian Splatting
Grzegorz Wilczyński, Rafał Tobiasz, Paweł Gora +2 more·Feb 4, 2026
Recent advances in neural rendering, particularly 3D Gaussian Splatting (3DGS), have enabled real-time rendering of complex scenes. However, standard 3DGS relies on spherical harmonics, which often struggle to accurately capture high-frequency view-d...
Minimal Hamiltonian deformations as bulk probes of effective non-Hermiticity in Dirac materials
Sergio Pino-Alarcón, Juan Pablo Esparza, Vladimir Juričić·Feb 4, 2026
Non-Hermitian (NH) Dirac semimetals describe open gain--loss systems, yet at charge neutrality models featuring real spectrum often look Hermitian-like, with NH effects absorbed into renormalized band parameters. Here we show that a response-based di...
From Fragmentation to Integration: Exploring the Design Space of AI Agents for Human-as-the-Unit Privacy Management
Eryue Xu, Tianshi Li·Feb 4, 2026
Managing one's digital footprint is overwhelming, as it spans multiple platforms and involves countless context-dependent decisions. Recent advances in agentic AI offer ways forward by enabling holistic, contextual privacy-enhancing solutions. Buildi...
Distributed Quantum Error Mitigation: Global and Local ZNE encodings
Maria Gragera Garces·Feb 4, 2026
Errors are the primary bottleneck preventing practical quantum computing. This challenge is exacerbated in the distributed quantum computing regime, where quantum networks introduce additional communication-induced noise. While error mitigation techn...
Taming multiparty entanglement at measurement-induced phase transitions
Liuke Lyu, James Allen, Yi Hong Teoh +2 more·Feb 4, 2026
Measurement-induced phase transitions (MIPT) give rise to novel dynamical states of quantum matter realized by balancing unitary evolution and measurements. We present large-scale numerical simulations of a trapped-ion native MIPT, argued to belong t...
Tighter Asymptotic Key Rates for Intensity-Correlated Decoy-State QKD via Nonlinear Programming
Matej Pivoluska, Mateus Araújo·Feb 4, 2026
Decoy-state QKD with phase-randomized weak coherent pulses is typically analyzed assuming independent, precisely prepared intensities. Real sources, however, can exhibit correlated intensity drift across rounds, potentially leaking intensity informat...
Constraints on stability and renormalization group flows in nonequilibrium matter
Yu-Hsueh Chen, Tarun Grover·Feb 4, 2026
We derive constraints on renormalization group (RG) flows and stability of phases in nonequilibrium systems using quantum information inequalities. These constraints involve conditional mutual information (CMI), which quantifies correlations between ...
Topological frustration and quantum resources
Alberto Giuseppe Catalano, Gianpaolo Torre, Salvatore Marco Giampaolo +1 more·Feb 4, 2026
Although in general boundary conditions do not affect the bulk properties of a system, some of them are special and defy such expectation. This is the case, for instance, of those inducing geometrical frustration in a classical magnet. Recently, the ...
Efficient time-evolution of matrix product states using average Hamiltonians
Belal Abouraya, Jirawat Saiphet, Fedor Jelezko +1 more·Feb 4, 2026
Simulating quantum many-body systems (QMBS) is one of the long-standing, highly non-trivial challenges in condensed matter physics and quantum information due to the exponentially growing size of the system's Hilbert space. To date, tensor networks h...
Towards $2+1$D quantum electrodynamics on a cold-atom quantum simulator
Peter Majcen, Jesse J. Osborne, Philipp Hauke +3 more·Feb 4, 2026
Cold atoms have become a powerful platform for quantum-simulating lattice gauge theories in higher spatial dimensions. However, such realizations have been restricted to the lowest possible truncations of the gauge field, which limit the connections ...
Emergence of Krylov complexity through quantum walks: An exploration of the quantum origins of complexity
Dimitrios Patramanis, Watse Sybesma·Feb 4, 2026
In this work we study the relationship between quantum random walks on graphs and Krylov/spread complexity. We show that the latter's definition naturally emerges through a canonical method of reducing a graph to a chain, on which we can identify the...
Information, Dissipation, and Planckian Optimality
Debanjan Chowdhury·Feb 4, 2026
We derive a universal bound on the efficiency with which "dissipated" work can generate distinguishable changes in a quantum many-body state at a finite temperature, as quantified by the quantum Fisher information. The bound follows solely from the a...
