Macroscopic Quantum Interference of the Center-of-Mass Motion of Levitated Superconducting Microparticles enabled by Magnetic Higher-Order Traps
Jaume Cunill-Subiranas, Fabian Resare, Suocheng Zhao +4 more·Jul 3, 2026
We show how magnetostatic higher-order multipole traps can be used to generate macroscopic quantum interference of the motion of levitated superconducting microparticles. An appropriate combination of multipolar magnetic fields offers great versatili...
Minimal Proper Time and Deterministic Microstates: Emergent Quantum Fields and Relativistic Spacetime
Alessio Maiezza·Jul 3, 2026
We develop a top-down counterpart of the minimal proper-time formulation of quantum field theory previously introduced as an effective bottom-up framework. Starting from a deterministic pre-geometric substrate of causally ordered events, we show how ...
Device-independent Quantum Key Distribution in the commuting operator framework
Gereon Koßmann, René Schwonnek, Po-Chieh Liu +1 more·Jul 3, 2026
Device-independent quantum key distribution (DIQKD) is arguably the gold standard for secure quantum communication, as it aims to rely only on observed input-output statistics of an uncharacterized device which is only assumption to obey the laws of ...
A Pulsed Live-Cell Quantum Microscope for Entangled Solid State and Biological Qubits
Javier Noé Ramos-Silva, Sangjun Noh, Minghao Jiang +5 more·Jul 3, 2026
Two revolutions in quantum sensing are converging on the same microscope stage. Biological qubits have emerged as genetically encoded, optically addressable quantum systems inside live cells. Solid state spin based qubits have been entangled and used...
Comparing and learning figures of merit for quantum circuit compilation
Harshdeep Singh, Marvin Richter, Mats Granath +1 more·Jul 3, 2026
To make quantum algorithms executable on a particular quantum device, they need to be compiled into circuits that respect constraints of the quantum hardware. This compilation usually involves multiple steps, where many hardware-compatible circuits a...
Generating one-way computations with flow: flow-preserving rewriting that ignores the interpretation
Miriam Backens·Jul 3, 2026
The one-way model is a universal model of quantum computation, driven by successive adaptive single-qubit measurements on an entangled resource state. Measurements are non-deterministic, yet if the computation satisfies one of several related familie...
Data-driven multi-objective optimization for alloy recycling using factorization machines and quantum annealing
Thomas Plehn, Katrin Bugelnig, Silvana Tumminello +2 more·Jul 3, 2026
Quantum annealing has the potential to provide practical quantum advantage for complex optimization tasks. Here, we present a systematic assessment of an integrated factorization-machine and quantum-annealing workflow (FM+QA) for a technologically re...
On the emergence of quantum many-body chaos for tunably-broken integrability
Sounak Biswas, Sthitadhi Roy, Roderich Moessner·Jul 2, 2026
We develop a quantitative theory for the emergence of quantum many-body chaos as integrability is broken via a tunable parameter. In a circuit model of free fermions, 'doped' with a tunable density of integrability-breaking gates, we uncover the micr...
Automated logical Clifford gadgets for heterogeneous architectures via chain maps
Asmae Benhemou, Noah Berthusen·Jul 2, 2026
Transversal CNOTs are ubiquitous for entangling logical qubits of identical CSS codes pairwise. For distinct codes, the options are much more limited, and are typically known only for structurally related code families. We introduce an automated fram...
Symmetries of Pauli Noise from Lindbladian Dynamics
Moein Malekakhlagh, Edward H. Chen, Luke C. G. Govia +1 more·Jul 2, 2026
Characterizing noise in quantum circuits is fundamentally limited by gauge degrees of freedom; certain parameters, such as the individual contributions of state preparation and measurement (SPAM) errors, are in principle unlearnable from any experime...
Topological Control of Quantum Chaos Diagnostics: OTOCs, Spectral Statistics, and Information Scrambling in Ising Model
Reza Pirmoradian, Soheir Rouhani, M. Reza Tanhayi·Jul 2, 2026
We investigate the integrability-to-chaos transition and information scrambling in Ising spin networks via a graph-theoretic formulation. Modeling spins as vertices and interactions via adjacency matrices across path, Erdős--Rényi, and Watts--Strogat...
Quantum mutual information as a robust probe of integrability in open quantum systems
Nirupam Sen, Keshav Das Agarwal, Aditi Sen De·Jul 2, 2026
The dynamics of a quantum system encode signatures of whether the underlying Hamiltonian is integrable or chaotic, giving rise to the concept of quantum information scrambling through the properties of the resulting dynamical states or operators. We ...
A Quantum-Walk Representation of Color-Ordered MHV Scattering Amplitudes
Anirudh Verma, C. M. Chandrashekar·Jul 2, 2026
We introduce a graph-theoretic framework for representing color-ordered maximally helicity violating (MHV) scattering amplitudes in quantum chromodynamics using coined quantum walks on permutation trees. Each root-to-terminal path corresponds to a di...
Optimal Stabilizer Testing and Learning with Limited Quantum Memory
Srinivasan Arunachalam, Louis Schatzki·Jul 2, 2026
We study stabilizer state testing and learning with limited coherent quantum memory. Here an algorithm sequentially receives copies of an unknown $n$-qubit state, but may keep only $k$ qubits of coherent quantum memory between measurements. With unre...
Optimal stellar rank approximation of squeezed cat states with photon catalysis
Julian K. Nauth, Nathan Walk, Ananga M. Datta +4 more·Jul 2, 2026
Non-Gaussian quantum states and operations constitute essential resources for achieving quantum computational advantage and enabling quantum error correction in bosonic platforms. However, their generation in optical settings remains a challenging ex...
Copying Quantum States
Hans Maassen, Burkhard Kümmerer·Jul 2, 2026
The no-broadcasting theorem in quantum information says that a set of states on a quantum system admits a common broadcasting (copying) operation if and only if their density matrices belong to a commuting family. We discuss and prove this theorem, a...
Stable Self-Modulating Quantum Fast-Weight Programmers with Bounded Memory Gates
Kuo-Chung Peng, Jiun-Cheng Jiang, Chun-Hua Lin +8 more·Jul 2, 2026
Quantum Fast-Weight Programmers (QFWPs) store temporal information in dynamically programmed variational-circuit parameters rather than in nonlinear recurrent hidden states, offering a practical route to quantum sequence modeling. Self-Modulating QFW...
Data Comics for Education: Evaluating Effectiveness, Benefits, and the Ethics of AI-Assisted Creation
Zirui Shan, Vanessa Echeverria, Yuheng Li +2 more·Jul 2, 2026
In today's data-driven world, students often struggle with interpreting visualisations due to limited visualisation literacy. Data comics have emerged as a promising medium to enhance engagement and understanding, but their educational value has seen...
Correlation and entanglement dynamics of free fermions in disguise
Dávid Szász-Schagrin, Pablo Bayona-Pena, Lorenzo Piroli +1 more·Jul 2, 2026
We study the nonequilibrium dynamics following a quantum quench in spin chains that can be solved via a mapping to free fermions in disguise. These models feature an exponential degeneracy of all energy eigenvalues, raising the question of the validi...
Recovery Algorithm for Correlated Errors in Permutation-Invariant Quantum Codes
Omprakash Chandra, Yingkai Ouyang, Gopikrishnan Muraleedharan +1 more·Jul 2, 2026
Quantum Error Recovery (QER) uses knowledge of the error channel acting on a quantum system to find optimal recovery maps. The scheme restores the uncorrupted state with a fidelity exceeding that achieved by noise parameter independent quantum error ...
