Fast and Robust Remote Two-Qubit Gates on Distributed Qubits
Yunan Li, Xi Zhang, Weixin Zhang +4 more·Nov 3, 2025
Distributed quantum computing offers a potential solution to the complexity of superconducting chip hardware layouts and error correction algorithms. High-quality gates between distributed chips enable the simplification of existing error correction ...
Super-resolved reconstruction of single-photon emitter locations from $g^{(2)}(0)$ maps
Sonali Gupta, Amit Kumar, Vikas S Bhat +1 more·Nov 3, 2025
Single-photon sources are vital for emerging quantum technologies. In particular, Nitrogen-vacancy (NV) centers in diamond are promising due to their room-temperature stability, long spin coherence, and compatibility with nanophotonic structures. A k...
Open-Source Highly Parallel Electromagnetic Simulations for Superconducting Circuits
David Sommers, Zach Degnan, Divita Gautam +4 more·Nov 3, 2025
Electromagnetic simulations form an indispensable part of the design and optimization process for superconducting quantum devices. Although several commercial platforms exist, open-source alternatives optimized for high-performance computing remain l...
Robust Quantum State Generation in Symmetric Spin Networks
Andre Luiz P. de Lima, Luke S. Baker, Anatoly Zlotnik +3 more·Nov 2, 2025
In this work, we consider a parameterized Ising model with long-range symmetric pairwise interactions on a network of spin $\frac{1}{2}$ particles. The system is designed with symmetric dynamics, allowing for the reduction of the state space to a sub...
In situ calibration of unitary operations during quantum error correction
Jonathan Kunjummen, Jacob M. Taylor·Nov 2, 2025
Quantum error correction uses the measurement of syndromes and classical decoding algorithms to estimate the location and type of errors while protecting the encoded quantum bits. Here we consider how prior information and Bayesian updates can play a...
Quantum Network Tomography for General Topology with SPAM Errors
Xuchuang Wang, Matheus Guedes De Andrade, Guus Avis +3 more·Nov 2, 2025
The goal of quantum network tomography (QNT) is the characterization of internal quantum channels in a quantum network from external peripheral operations. Prior research has primarily focused on star networks featuring bit-flip and depolarizing chan...
Quantum dynamics in lattices in presence of bulk dephasing and a localized source
Tamoghna Ray, Katha Ganguly, Dario Poletti +2 more·Nov 1, 2025
The aim of this work is to study the dynamics of quantum systems subjected to a localized fermionic source in the presence of bulk dephasing. We consider two classes of one-dimensional lattice systems: (i) a non-interacting lattice with nearest-neigh...
Hadronic scattering in (1+1)D SU(2) lattice gauge theory from tensor networks
João Barata, Juan Hormaza, Zhong-Bo Kang +1 more·Oct 31, 2025
We present a first real-time study of hadronic scattering in a (1+1)-dimensional SU(2) lattice gauge theory with fundamental fermions using tensor-network techniques. Working in the gaugeless Hamiltonian formulation -- where the gauge field is exactl...
Scalable quantum computation of Quantum Electrodynamics beyond one spatial dimension
Zong-Gang Mou, Bipasha Chakraborty·Oct 31, 2025
In the Hamiltonian formulation, Quantum Field Theory calculations scale exponentially with spatial volume, making real-time simulations intractable on classical computers and motivating quantum computation approaches. In Hamiltonian quantisation, bos...
Long-lived giant circular Rydberg atoms at room temperature
Einius Pultinevicius, Aaron Götzelmann, Fabian Thielemann +2 more·Oct 31, 2025
Stability achieved by large angular momentum is ubiquitous in nature, with examples ranging from classical mechanics, over optics and chemistry, to nuclear physics. In atoms, angular momentum can protect excited electronic orbitals from decay due to ...

Philipp J. Vetter, Christoph Findler, Antonio Verdú +8 more·Oct 31, 2025
Quantum simulation aims to recreate complex many-body phenomena in controlled environments, offering insights into dynamics that are otherwise difficult to model. Existing platforms, however, are often complex and costly to scale, typically requiring...
Instruction-Directed MAC for Efficient Classical Communication in Scalable Multi-Chip Quantum Systems
Maurizio Palesi, Enrico Russo, Hamaad Rafique +4 more·Oct 31, 2025
Scalable quantum computing requires modular multi-chip architectures integrating multiple quantum cores interconnected through quantum-coherent and classical links. The classical communication subsystem is critical for coordinating distributed contro...
Geometry-Driven Resonance and Localization of Light in Fractal Phase Spaces
L. Yıldız, D. Kaykı, M. F. Ciappina·Oct 31, 2025
Geometry can fundamentally govern the propagation of light, independent of material constraints. Here, we demonstrate that a fractal phase space, endowed with a non-Euclidean, scale-dependent geometry, can intrinsically induce resonance quantization,...

Noah Gorgichuk, Mohammad Ayyash, Matteo Mariantoni +1 more·Oct 30, 2025
We present a protocol for preparing oscillator states with $n$-fold rotational symmetry, which include many logical codewords for bosonic quantum error correction codes. The protocol relies on a multiphoton interaction between the oscillator and an a...
