CUNQA: a Distributed Quantum Computing emulator for HPC

Jorge Vázquez-Pérez, Daniel Expósito-Patiño, Marta Losada, Álvaro Carballido, Andrés Gómez, Tomás F. Pena • Published: 2025-11-07
The challenge of scaling quantum computers to gain computational power is expected to lead to architectures with multiple connected quantum processing units (QPUs), commonly referred to as Distributed Quantum Computing (DQC). In parallel, there is a growing momentum toward treating quantum computers as accelerators, integrating them into the heterogeneous architectures of high-performance computin...

Architecting Scalable Trapped Ion Quantum Computers using Surface Codes

Scott Jones, Prakash Murali • Published: 2025-10-27
Trapped ion (TI) qubits are a leading quantum computing platform. Current TI systems have less than 60 qubits, but a modular architecture known as the Quantum Charge-Coupled Device (QCCD) is a promising path to scale up devices. There is a large gap between the error rates of near-term systems ($10^{-3}$ to $10^{-4}$) and the requirements of practical applications (below $10^{-9}$). To bridge this...

Quantum computation of a quasiparticle band structure with the quantum-selected configuration interaction

Takahiro Ohgoe, Hokuto Iwakiri, Kazuhide Ichikawa, Sho Koh, Masaya Kohda • Published: 2025-04-01
Quasiparticle band structures are fundamental for understanding strongly correlated electron systems. While solving these structures accurately on classical computers is challenging, quantum computing offers a promising alternative. Specifically, the quantum subspace expansion (QSE) method, combined with the variational quantum eigensolver (VQE), provides a quantum algorithm for calculating quasip...

Network-assisted collective operations for efficient distributed quantum computing

Iago Fernández Llovo, Guillermo Díaz-Camacho, Natalia Costas Lago, Andrés Gómez Tato • Published: 2025-02-26
Distributed quantum computing relies on coordinated operations between remote quantum processing units (QPUs), yet most existing work either assumes full connectivity, unrealistic for large networks, or relies on entanglement swapping. To mitigate the overhead of communication, we propose a scheme for the distribution of collective quantum operations among remote quantum processing units by exploi...

Neutral-atom quantum computation using multi-qubit geometric gates via adiabatic passage

Sinchan Snigdha Rej, Bimalendu Deb • Published: 2025-11-06
Adiabatic geometric phase gates offer enhanced robustness against fluctuations compared to con- ventional Rydberg blockade-based phase gates that rely on dynamical phase accumulation. We theoretically demonstrate two- and multi-qubit phase gates in a neutral atom architecture, relying on a double stimulated Raman adiabatic passage (double-STIRAP) pulse sequence that imprints a controllable geometr...

Bridging Quantum Computing and Nuclear Structure: Atomic Nuclei on a Trapped-Ion Quantum Computer

Sota Yoshida, Takeshi Sato, Takumi Ogata, Masaaki Kimura • Published: 2025-09-25
We demonstrate quantum simulations of strongly correlated nuclear many-body systems on the RIKEN-Quantinuum Reimei trapped-ion quantum computer, targeting ground states of oxygen, calcium, and nickel isotopes. By combining a hard-core-boson representation of the nuclear shell model with a pair-unitary coupled-cluster doubles ansatz, we achieve sub-percent relative error in the ground-state energie...

Realistic GKP stabilizer states enable universal quantum computation

Fariba Hosseinynejad, Pavithran Iyer, Guillaume Dauphinais, David L. Feder • Published: 2025-11-05
Physical Gottesman-Kitaev-Preskill (GKP) states are inherently noisy as ideal ones would require infinite energy. While this is typically considered as a deficiency to be actively corrected, this work demonstrates that imperfect GKP stabilizer states can be leveraged in order to apply non-Clifford gates using only linear optical elements. In particular, Gaussian operations on normalizable GKP stat...

Quantum computing offers a powerful new perspective on probabilistic and collective behaviors traditionally taught in statistical physics. This paper presents two classroom-ready modules that integrate quantum computing into the undergraduate curriculum using Qiskit: the quantum random walk and the Ising model. Both modules allow students to simulate and contrast classical and quantum systems, dee...

Security and Privacy Management of IoT Using Quantum Computing

Jaydip Sen • Published: 2025-11-05
The convergence of the Internet of Things (IoT) and quantum computing is redefining the security paradigm of interconnected digital systems. Classical cryptographic algorithms such as RSA, Elliptic Curve Cryptography (ECC), and Advanced Encryption Standard (AES) have long provided the foundation for securing IoT communication.

Quantum Tensor Representation via Circuit Partitioning and Reintegration

Ziqing Guo, Jan Balewski, Kewen Xiao, Ziwen Pan • Published: 2025-11-07
Quantum computing enables faster computations than clas-sical algorithms through superposition and entanglement. Circuit cutting and knitting are effective techniques for ame-liorating current noisy quantum processing unit (QPUs) er-rors via a divide-and-conquer approach that splits quantum circuits into subcircuits and recombines them using classical post-processing. The development of circuit pa...

Quantum advantage from effective $200$-qubit holographic random circuit sampling

Bingzhi Zhang, Quntao Zhuang • Published: 2025-11-07
Quantum computers hold the promise of outperforming classical computers in solving certain problems.

Random circuit sampling has emerged as a leading candidate for such demonstrations. However, existing implementations often u...

Application of Optimal Control to Time-Resolution Protocol for Quantum Sensing

Chungwei Lin, Qi Ding, Yanting Ma • Published: 2025-08-18
Time-resolution protocol of quantum sensing aims to measure the fast temporal variation of an external field and demands a high field sensitivity in a short interrogation time $\tau$. Since any operation that evolves the quantum state takes time and is counted as part of the interrogation, evaluating the performance of time-resolution protocol requires a complete end-to-end description of the meas...

Shallow IQP circuit and graph generation

Oriol Balló-Gimbernat, Marcos Arroyo-Sánchez, Paula García-Molina, Adan Garriga, Fernando Vilariño • Published: 2025-11-07
We introduce shallow instantaneous quantum polynomial-time (IQP) circuits as generative graph models, using an edge-qubit encoding to map graphs onto quantum states. Focusing on bipartite and Erd\H{o}s-R\'enyi distributions, we study their expressivity and robustness through simulations and large-scale experiments. Noiseless simulations of $28$ qubits ($8$-node graphs) reveal that shallow IQP mode...
