−Anchor: Reducing Temporal and Spatial Output Performance Variability on Quantum Computers
Yuqian Huo, Daniel Leeds, Jason Ludmir, Nicholas S. DiBrita, Tirthak Patel • Published: 2025-10-07
Quantum computing, which has the power to accelerate many computing
applications, is currently a technology under development. As a result, the
existing noisy intermediate-scale quantum (NISQ) computers suffer from
different hardware noise effects, which cause errors in the output of quantum
programs. These errors cause a high degree of variability in the performance
(i.e., output fidelity) of qua...
Hybrid Sequential Quantum Computing
Pranav Chandarana, Sebastián V. Romero, Alejandro Gomez Cadavid, Anton Simen, Enrique Solano, Narendra N. Hegade • Published: 2025-10-07
We introduce hybrid sequential quantum computing (HSQC), a paradigm for
combinatorial optimization that systematically integrates classical and quantum
methods within a structured, stage-wise workflow. HSQC may involve an arbitrary
sequence of classical and quantum processes, as long as the global result
outperforms the standalone components. Our testbed begins with classical
optimizers to explore...
Low Overhead Universal Quantum Computation with Triorthogonal Codes
Dawei Jiao, Mahdi Bayanifar, Alexei Ashikhmin, Olav Tirkkonen • Published: 2025-10-07
We explore the use of triorthogonal codes for universal fault-tolerant
quantum computation and propose two methods to circumvent the Eastin-Knill
theorem, which prohibits any single quantum error-correcting code from
supporting both universality and a transversal gate set. First, we simplify the
implementation of the logical Hadamard gate for triorthogonal codes by
exploiting the fact that they ha...
Invested and Potential Magic Resources in Measurement-Based Quantum Computation
Gongchu Li, Lei Chen, Si-Qi Zhang, Xu-Song Hong, Huaqing Xu, Yuancheng Liu, You Zhou, Geng Chen, Chuan-Feng Li, Alioscia Hamma, Guang-Can Guo • Published: 2024-08-04
Magic states and magic gates are crucial for achieving universal quantum
computation, but important questions about how magic resources should be
implemented to attain maximal quantum advantage have remained unexplored,
especially in the context of measurement-based quantum computation (MQC). This
work bridges the gap between MQC and the resource theory of magic by
introducing the key concepts of ...
Fermionic Insights into Measurement-Based Quantum Computation: Circle Graph States Are Not Universal Resources
Brent Harrison, Vishnu Iyer, Ojas Parekh, Kevin Thompson, Andrew Zhao • Published: 2025-10-07
Measurement-based quantum computation (MBQC) is a strong contender for
realizing quantum computers. A critical question for MBQC is the identification
of resource graph states that can enable universal quantum computation. Any
such universal family must have unbounded entanglement width, which is known to
be equivalent to the ability to produce any circle graph state from the states
in the family ...
Probing the Kitaev honeycomb model on a neutral-atom quantum computer
Simon J. Evered, Marcin Kalinowski, Alexandra A. Geim, Tom Manovitz, Dolev Bluvstein, Sophie H. Li, Nishad Maskara, Hengyun Zhou, Sepehr Ebadi, Muqing Xu, Joseph Campo, Madelyn Cain, Stefan Ostermann, Susanne F. Yelin, Subir Sachdev, Markus Greiner, Vladan Vuletić, Mikhail D. Lukin • Published: 2025-01-30
Quantum simulations of many-body systems are among the most promising
applications of quantum computers. In particular, models based on
strongly-correlated fermions are central to our understanding of quantum
chemistry and materials problems, and can lead to exotic, topological phases of
matter. However, due to the non-local nature of fermions, such models are
challenging to simulate with qubit de...
Fault-tolerant interfaces for modular quantum computing on diverse qubit platforms
Frederik K. Marqversen, Gefen Baranes, Maxim Sirotin, Johannes Borregaard • Published: 2025-10-06
Modular architectures offer a scalable path toward fault-tolerant quantum
computing by interconnecting smaller quantum processing units (QPUs) provided
that high-rate, fault-tolerant interfaces can be realized across modules. We
present a comprehensive analysis and comparison of known and new methods for
establishing such interfaces, including lattice surgery, transversal gates, and
novel grow-and...
Symmetric quantum computation
Davi Castro-Silva, Tom Gur, Sergii Strelchuk • Published: 2025-01-02
We introduce a systematic study of "symmetric quantum circuits", a new
restricted model of quantum computation that preserves the symmetries of the
problems it solves. This model is well-adapted for studying the role of
symmetry in quantum speedups, extending a central notion of symmetric
computation studied in the classical setting.
Our results establish that symmetric quantum circuits are fund...

Quantum systems have started to emerge as a disruptive technology and
enabling platforms - exploiting the principles of quantum mechanics via
programmable quantum bits (QuBits) - to achieve quantum supremacy in computing.

Leveraging Analog Neutral Atom Quantum Computers for Diversified Pricing in Hybrid Column Generation Frameworks
Cédrick Perron, Yves Bérubé-Lauzière, Victor Drouin-Touchette • Published: 2025-10-06
In this work, we develop new pulse designs and embedding strategies to
improve the analog quantum subroutines of hybrid column generation (CG)
algorithms based on neutral-atoms quantum computers (NAQCs). These strategies
are designed to improve the quality and diversity of the samples generated. We
apply these to an important combinatorial optimization (CO) problem in
logistics, namely the fleet a...

−Automated Program Repair of Uncompilable Student Code
Griffin Pitts, Aum Pandya, Darsh Rank, Tirth Bhatt, Muntasir Hoq, Bita Akram • Published: 2025-10-07
A significant portion of student programming submissions in CS1 learning
environments are uncompilable, limiting their use in student modeling and
downstream knowledge tracing. Traditional modeling pipelines often exclude
these cases, discarding observations of student learning. This study
investigates automated program repair as a strategy to recover uncompilable
code while preserving students' s...
Benchmark It Yourself (BIY): Preparing a Dataset and Benchmarking AI Models for Scatterplot-Related Tasks
João Palmeiro, Diogo Duarte, Rita Costa, Pedro Bizarro • Published: 2025-10-07
AI models are increasingly used for data analysis and visualization, yet
benchmarks rarely address scatterplot-specific tasks, limiting insight into
performance. To address this gap for one of the most common chart types, we
introduce a synthetic, annotated dataset of over 18,000 scatterplots from six
data generators and 17 chart designs, and a benchmark based on it. We evaluate
proprietary models...

Schneider, F. Wallner, D. Bunch, L. Richard, L. Södergren, K. Liegener, M. Werninghaus, S. Filipp • Published: 2024-03-04
As systems for quantum computing keep growing in size and number of qubits,
challenges in scaling the control capabilities are becoming increasingly
relevant. Efficient schemes to simultaneously mediate coherent interactions
between multiple quantum systems and to reduce decoherence errors can minimize
the control overhead in next-generation quantum processors. Here, we present a
superconducting q...

patient-provider interaction but also introduce severe and often underexamined
security and privacy risks. We present an end-to-end audit of 272 Android
mHealth apps from Google Play, combining permission forensics, static
vulnerability analysis, and user review mining. Our multi-tool assessment with
MobSF, RiskInDroid, and OW...
Quantum Lattice Boltzmann Method for Multiple Time Steps Without Reinitialization for Linear Advection-Diffusion Problems
Aaron Nagel, Johannes Löwe • Published: 2025-10-07
To simulate highly-resolved flow fields, we extend the Quantum Lattice
Boltzmann Method (QLBM) to be able to simulate multiple time steps without
state extraction or reinitialization. We adjust and extend given QLBM
approaches from the literature to completely remove the need to measure or
reinitialize the flow field in between the simulation time steps. Therefore,
our algorithm does not require t...
Structured Sparse Transition Matrices to Enable State Tracking in State-Space Models
Aleksandar Terzić, Nicolas Menet, Michael Hersche, Thomas Hofmann, Abbas Rahimi • Published: 2025-09-26
Modern state-space models (SSMs) often utilize transition matrices which
enable efficient computation but pose restrictions on the model's expressivity,
as measured in terms of the ability to emulate finite-state automata (FSA).
While unstructured transition matrices are optimal in terms of expressivity,
they come at a prohibitively high compute and memory cost even for moderate
state sizes. We pr...
Fast and Robust Non-Adiabatic Holonomic Gates for Qutrit Systems
Jie Lu, Jie-Dong Huang, Yang Qian, Ying Yan • Published: 2025-10-07
Motivated by shortcuts to adiabaticity, we develop a framework that combines
inverse engineering with time-dependent perturbation theory to implement
non-adiabatic holonomic quantum computing (NHQC) in qutrit systems under
realistic error sources. We derive analytical conditions that suppress
second-order Rabi errors through tailored pulse parameters and eliminate
detuning errors via a compensatio...
Hybrid quantum-classical analog simulation of two-dimensional Fermi-Hubbard models with neutral atoms
Sergi Julià-Farré, Antoine Michel, Christophe Domain, Joseph Mikael, Jacques-Charles Lafoucriere, Joseph Vovrosh, Ahmed Chahlaoui, Dorian Claveau, Guillaume Villaret, Julius de Hond, Loïc Henriet, Antoine Browaeys, Thomas Ayral, Alexandre Dauphin • Published: 2025-10-07
We experimentally study the two-dimensional Fermi-Hubbard model using a
Rydberg-based quantum processing unit in the analog mode. Our approach avoids
encoding directly the original fermions into qubits and instead relies on
reformulating the original model onto a system of fermions coupled to spins and
then decoupling them in a self-consistent manner. We then introduce the
auxiliary spin solver: t...
