A method for the numerical analysis of hybrid lumped-distributed superconducting quantum circuits
Simona Zaccaria, Antonio Gnudi·Sep 3, 2025
We present a method for the numerical analysis of superconducting quantum circuits combining lumped elements, either linear or non-linear (i.e.~Josephson junctions), and distributed coplanar waveguide (CPW) structures. CPW transmission lines and mult...
Universal Crossover in the Three-Channel Charge Kondo Model at High Transparency
Nicolas Paris, Nicolas Dupuis, Christophe Mora·Sep 3, 2025
Quantum impurity models provide a central framework for correlated electron physics, with quantum dots enabling controlled experimental realizations. While their weak-coupling behavior is well understood through mappings to Kondo Hamiltonians, the op...
Detection of noise correlations in two qubit systems by Machine Learning
Dario Fasone, Shreyasi Mukherjee, Dario Penna +5 more·Sep 3, 2025
We introduce and validate a machine-learning assisted quantum sensing protocol to classify spatial and temporal correlations of classical noise affecting two ultrastrongly coupled qubits. We consider six distinct classes of Markovian and non-Markovia...
Evaluating Security Properties in the Execution of Quantum Circuits
Paolo Bernardi, Antonio Brogi, Gian-Luigi Ferrari +1 more·Sep 3, 2025
Quantum computing is a disruptive technology that is expected to offer significant advantages in many critical fields (e.g. drug discovery and cryptography). The security of information processed by such machines is therefore paramount. Currently, mo...
A Symmetry-Enabled Direct Quantum Protocol for Many-Body Green's Functions
Changhao Yi, Cunlu Zhou·Sep 3, 2025
We present a symmetry-enabled direct quantum protocol for computing many-body Green's functions, a central tool for studying strongly correlated quantum systems. Our protocol relies only on native time evolution and straightforward measurements avail...
A Deficiency-Based Approach for the Operational Interpretation of Quantum Resources with Applications
Sunho Kim, Chunhe Xiong, Junde Wu·Sep 3, 2025
A fundamental challenge in quantum resource theory is to establish operational interpretations by quantifying the advantage that quantum resources provide in specific tasks. Conventional resource theories, however, have inherent limitations in charac...
The Structure and Interpretation of Quantum Programs I: Foundations
D. Wakeham·Sep 3, 2025
Qubits are a great way to build a quantum computer, but a limited way to program one. We replace the usual"states and gates"formalism with a"props and ops"(propositions and operators) model in which (a) the C*-algebra of observables supplies the synt...
Effective Hamiltonian for an off-resonantly driven qubit-cavity system
Martin Jirlow, Kunal Helambe, Axel Eriksson +2 more·Sep 3, 2025
Accurate modeling of driven light-matter interactions is essential for quantum technologies, where natural and synthetic atoms are used to store and process quantum information, mediate interactions between bosonic modes, and enable nonlinear operati...
Quantum simulation of out-of-equilibrium dynamics in gauge theories
Jad C. Halimeh, Niklas Mueller, J. Knolle +2 more·Sep 3, 2025
Recent advances in quantum technologies have enabled quantum simulation of gauge theories -- some of the most fundamental frameworks of nature -- in regimes far from equilibrium, where classical computation is severely limited. These simulators, prim...
Programmable Quantum Matter: Heralding Large Cluster States in Driven Inhomogeneous Spin Ensembles
Pratyush Anand, Louis Follet, Odiel Hooybergs +1 more·Sep 3, 2025
Atom-like emitters in solids are promising platforms for quantum sensing and information processing, but inhomogeneities in the emitter fine structure complicate quantum control. We present a framework that leverages this diversity to reduce the reso...
Quantum optical reset with classical memory
E. Kiktenko, O. M. Sotnikov, I. A. Iakovlev +5 more·Sep 3, 2025
Dynamic quantum circuits generate states that depend on the measurement results obtained during circuit execution. To date such a quantum computing model has mainly been implemented with qubit-based superconducting hardware utilizing reset operations...
An angular momentum approach to quantum insertion errors
Lewis Bulled, Yingkai Ouyang·Sep 3, 2025
Quantum insertion errors are a class of errors that increase the number of qubits in a quantum system. Despite a wealth of research on classical insertion errors, there has been limited progress towards a general framework for correcting quantum inse...
Quantum-Assisted Correlation Clustering
A. Macaluso, Supreeth Mysore Venkatesh, Diego Arenas +2 more·Sep 3, 2025
This work introduces a hybrid quantum-classical method to correlation clustering, a graph-based unsupervised learning task that seeks to partition the nodes in a graph based on pairwise agreement and disagreement. In particular, we adapt GCS-Q [1], a...
Treasure Hunt in Anonymous Graphs with Quantum Pebbles by Oblivious Agents
Gaurav Gaur, B. Gorain, R. Singh +1 more·Sep 3, 2025
We investigate the problem of finding a static treasure in anonymous graphs using oblivious agents and introduce a novel approach that leverages quantum information. In anonymous graphs, vertices are unlabelled, indistinguishable, and edges are local...
The ITransverse.jl library for transverse tensor network contractions
Stefano Carignano·Sep 3, 2025
Transverse contraction methods are extremely promising tools for the efficient contraction of tensor networks associated with the time evolution of quantum many-body systems, allowing in some cases to circumvent the entanglement barrier that would no...
An experience-based classification of quantum bugs in quantum software
Nils Quetschlich, Olivia Di Matteo·Sep 3, 2025
As quantum computers continue to improve in quality and scale, there is a growing need for accessible software frameworks for programming them. However, the unique behavior of quantum systems means specialized approaches, beyond traditional software ...
