Enhanced Fault-tolerance in Photonic Quantum Computing: Comparing the Honeycomb Floquet Code and the Surface Code in Tailored Architecture

Théo Dessertaine, Boris Bourdoncle, Aurélie Denys, Grégoire de Gliniasty, Pierre Colonna d'Istria, Gerard Valentí-Rojas, Shane Mansfield, Paul HilairePublished: 2024-10-09
Fault-tolerant quantum computing is crucial for realizing large-scale quantum computation, and the interplay between hardware architecture and quantum error-correcting codes is a key consideration. We present a comparative study of two quantum error-correcting codes - the surface code and the honeycomb Floquet code - implemented on the spin-optical quantum computing architecture, either with contr...

Minimally Universal Parity Quantum Computing

Isaac D. Smith, Berend Klaver, Hendrik Poulsen Nautrup, Wolfgang Lechner, Hans J. BriegelPublished: 2025-04-04
In parity quantum computing, multi-qubit logical gates are implemented by single-qubit rotations on a suitably encoded state involving auxiliary qubits. Consequently, there is a correspondence between qubit count and the size of the native gate set. One might then wonder: what is the smallest number of auxiliary qubits that still allows for universal parity computing? Here, we demonstrate that the...

Time-tronics: from temporal printed circuit board to quantum computer

Krzysztof Giergiel, Peter Hannaford, Krzysztof SachaPublished: 2024-06-10
Time crystalline structures can be created in periodically driven systems. They are temporal lattices which can reveal different condensed matter behaviours ranging from Anderson localization in time to temporal analogues of many-body localization or topological insulators. However, the potential practical applications of time crystalline structures have yet to be explored. Here, we pave the way f...

This paper provides an initial exploration into the realm of quantum computational insurance...

Lightweight Targeted Estimation of Layout Noise in a Quantum Computer using Quality Indicator Circuits

Shikhar Srivastava, Ritajit Majumdar, Padmanabha Venkatagiri Seshadri, Anupama Ray, Yogesh SimmhanPublished: 2025-09-23
In the current era of quantum computing, minimizing noise is essential for reliably executing quantum circuits on hardware. A key factor affecting circuit performance is the mapping of the abstract quantum circuit to the physical layout of the quantum hardware. This mapping can significantly influence output quality, especially since hardware noise profiles are non-uniform and dynamic. Existing so...

Connecting Quantum Computing with Classical Stochastic Simulation

Jose Blanchet, Mark S. Squillante, Mario Szegedy, Guanyang WangPublished: 2025-09-23
This tutorial paper introduces quantum approaches to Monte Carlo computation with applications in computational finance. We outline the basics of quantum computing using Grover's algorithm for unstructured search to build intuition. We then move slowly to amplitude estimation problems and applications to counting and Monte Carlo integration, again using Grover-type iterations. A hands-on Python/Qi...

A Quantum Computational Determination of the Weak Mixing Angle in the Standard Model

Qiaofeng Liu, Ian Low, Zhewei YinPublished: 2025-09-22
The weak mixing angle $s_W$ is a fundamental constant in the Standard Model (SM) and measured at the $Z$ boson mass to be $\widehat{s}^2_W(m_Z) = 0.23129 \pm 0.00004$ in the $\overline{\rm MS}$ renormalization scheme, where $m_Z=91.2\ \text{GeV}$. On the other hand, non-stabilizerness - the magic - characterizes the computational advantage of a quantum system over classical computers. We consider ...

TASI/CERN/KITP Lecture Notes on "Toward Quantum Computing Gauge Theories of Nature"

Zohreh DavoudiPublished: 2025-07-21
A hallmark of the computational campaign in nuclear and particle physics is the lattice-gauge-theory program. It continues to enable theoretical predictions for a range of phenomena in nature from the underlying Standard Model. The emergence of a new computational paradigm based on quantum computing, therefore, can introduce further advances in this program. In particular, it is believed that quan...

Enhanced fill probability estimates in institutional algorithmic bond trading using statistical learning algorithms with quantum computers

Axel Ciceri, Austin Cottrell, Joshua Freeland, Daniel Fry, Hirotoshi Hirai, Philip Intallura, Hwajung Kang, Chee-Kong Lee, Abhijit Mitra, Kentaro Ohno, Das Pemmaraju, Manuel Proissl, Brian Quanz, Del Rajan, Noriaki Shimada, Kavitha YograjPublished: 2025-09-22
The estimation of fill probabilities for trade orders represents a key ingredient in the optimization of algorithmic trading strategies. It is bound by the complex dynamics of financial markets with inherent uncertainties, and the limitations of models aiming to learn from multivariate financial time series that often exhibit stochastic properties with hidden temporal patterns. In this paper, we f...

Parton Distributions on a Quantum Computer

Jiunn-Wei Chen, Yu-Ting Chen, Ghanashyam MeherPublished: 2025-06-20
We perform the first quantum computation of parton distribution function (PDF) with a real quantum device by calculating the PDF of the lightest positronium in the Schwinger model with IBM quantum computers. The calculation uses 10 qubits for staggered fermions at five spatial sites and one ancillary qubit. The most critical and challenging step is to reduce the number of two-qubit gate depths to ...

Not All Qubits are Utilized Equally

Jeremie Pope, Swaroop GhoshPublished: 2025-09-23
Improvements to the functionality of modern Noisy Intermediate-Scale Quantum (NISQ) computers have coincided with an increase in the total number of physical qubits. Quantum programmers do not commonly design circuits that directly utilize these qubits; instead, they rely on various software suites to algorithmically transpile the circuit into one compatible with a target machine's architecture. F...

Gate-Based and Annealing-Based Quantum Algorithms for the Maximum K-Plex Problem

Xiaofan Li, Gao Cong, Rui ZhouPublished: 2025-09-23
The $ k $-plex model, which allows each vertex to miss connections with up to $ k $ neighbors, serves as a relaxation of the clique. Its adaptability makes it more suitable for analyzing real-world graphs where noise and imperfect data are common and the ideal clique model is often impractical. The problem of identifying the maximum $ k $-plex (MKP, which is NP-hard) is gaining attention in fields...

Confidential LLM Inference: Performance and Cost Across CPU and GPU TEEs

Marcin Chrapek, Marcin Copik, Etienne Mettaz, Torsten HoeflerPublished: 2025-09-23
Large Language Models (LLMs) are increasingly deployed on converged Cloud and High-Performance Computing (HPC) infrastructure. However, as LLMs handle confidential inputs and are fine-tuned on costly, proprietary datasets, their heightened security requirements slow adoption in privacy-sensitive sectors such as healthcare and finance. We investigate methods to address this gap and propose Trusted ...

Yanlong Chen, Mattia Orlandi, Pierangelo Maria Rapa, Simone Benatti, Luca Benini, Yawei LiPublished: 2025-06-12
Human-machine interaction, particularly in prosthetic and robotic control, has seen progress with gesture recognition via surface electromyographic (sEMG) signals.However, classifying similar gestures that produce nearly identical muscle signals remains a challenge, often reducing classification accuracy. Traditional deep learning models for sEMG gesture recognition are large and computationally e...
