Anchor: Reducing Temporal and Spatial Output Performance Variability on Quantum Computers

Yuqian Huo, Daniel Leeds, Jason Ludmir, Nicholas S. DiBrita, Tirthak PatelPublished: 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. HegadePublished: 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 TirkkonenPublished: 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 GuoPublished: 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 ZhaoPublished: 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 ...

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. LukinPublished: 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 BorregaardPublished: 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 StrelchukPublished: 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...

Cédrick Perron, Yves Bérubé-Lauzière, Victor Drouin-TouchettePublished: 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...

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...

João Palmeiro, Diogo Duarte, Rita Costa, Pedro BizarroPublished: 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...

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...

Quantum Lattice Boltzmann Method for Multiple Time Steps Without Reinitialization for Linear Advection-Diffusion Problems

Aaron Nagel, Johannes LöwePublished: 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 RahimiPublished: 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 YanPublished: 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 DauphinPublished: 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...
