On the Design of Expressive and Trainable Pulse-based Quantum Machine Learning Models
Han-Xiao Tao, Xin Wang, Re-Bing Wu·Aug 7, 2025
Pulse-based Quantum Machine Learning (QML) has emerged as a novel paradigm in quantum artificial intelligence due to its exceptional hardware efficiency. For practical applications, pulse-based models must be both expressive and trainable. Previous s...
Taming coherent noise with teleportation
Kathleen M. Chang, Qile Su, S. Puri·Aug 7, 2025
Compared to the more widely studied Pauli errors, coherent errors present several new challenges in quantum computing and quantum error correction (QEC). For example, coherent errors may interfere constructively over a long circuit and significantly ...
Ultra-Large-Scale Compilation and Manipulation of Quantum Circuits with Pandora
Ioana Moflic, A. Paler·Aug 7, 2025
There is an enormous gap between what quantum circuit sizes can be compiled and manipulated with the current generation of quantum software and the sizes required by practical applications such as quantum chemistry or Shor's algorithm. We present Pan...
Modular Quantum Amplitude Estimation: A Scalable and Adaptive Framework
Alok Shukla, P. Vedula·Aug 7, 2025
Quantum Amplitude Estimation (QAE) is a key primitive in quantum computing, but its standard implementation using Quantum Phase Estimation is resource-intensive, requiring a large number of coherent qubits in a single circuit block to achieve high pr...
Efficient Quantum Implementation of Dynamical Mean Field Theory for Correlated Materials
N. Hogan, Efekan Kokcu, Thomas Steckmann +6 more·Aug 7, 2025
The accurate theoretical description of materials with strongly correlated electrons is a formidable challenge in condensed matter physics and computational chemistry. Dynamical Mean Field Theory (DMFT) is a successful approach that predicts behavior...
Material-Driven Optimization of Transmon Qubits for Scalable and Efficient Quantum Architectures
Jonnalagadda Gayatri, S. Veni·Aug 7, 2025
One of the most crucial steps in creating practical quantum computers is designing scalable and efficient superconducting qubits. Coherence times, connections between individual qubits, and reduction of environmental noise are critical factors in the...
Quantum Path Signatures
Samuel Crew, C. Salvi, William F. Turner +2 more·Aug 7, 2025
We elucidate physical aspects of path signatures by formulating randomised path developments within the framework of matrix models in quantum field theory. Using tools from physics, we introduce a new family of randomised path developments and derive...
Bipartite entanglement in a nuclear spin register mediated by a quasi-free electron spin
Marco Klotz, Andreas Tangemann, David Opferkuch +1 more·Aug 7, 2025
Quantum networks will rely on photons entangled to robust, local quantum registers for computation and error correction. We demonstrate control of and entanglement in a fully connected three-qubit 13C nuclear spin register in diamond. The register is...
Minimum-Weight Parity Factor Decoder for Quantum Error Correction
Yue Wu, Binghong Li, Kathleen M. Chang +2 more·Aug 7, 2025
Fast and accurate quantum error correction (QEC) decoding is crucial for scalable fault-tolerant quantum computation. Most-Likely-Error (MLE) decoding, while being near-optimal, is intractable on general quantum Low-Density Parity-Check (qLDPC) codes...
Coniq: Enabling Concatenated Quantum Error Correction on Neutral Atom Arrays
Pengyu Liu, Mingkuan Xu, Hengyun Zhou +3 more·Aug 7, 2025
Recent progress on concatenated codes, especially many-hypercube codes, achieves unprecedented space efficiency. Yet two critical challenges persist in practice. First, these codes lack efficient implementations of addressable logical gates. Second, ...
Tailored First-order and Interior-point methods and a new semidefinite programming hierarchy for entanglement detection
Javier F. Peña, Vikesh Siddhu, Sridhar Tayur·Aug 7, 2025
Quantum entanglement lies at the heart of quantum information science, yet its reliable detection in high-dimensional or noisy systems remains a fundamental computational challenge. Semidefinite programming (SDP) hierarchies, such as the Doherty-Parr...

Noise-resilient Universal Quantum Computing in the Presence of Anisotropic Noise
Yang-Yang Xie, Zhao-Ming Wang, Lian-Ao Wu·Aug 6, 2025
We propose a universal gate set for quantum computing that operates in the presence of decoherence without the overhead of active error correction. We show that a broad class of anisotropic system--bath couplings can be effectively decoupled by prepa...
