−Quantum computing on encrypted data with arbitrary rotation gates
Mohit Joshi, Manoj Kumar Mishra, S. Karthikeyan • Published: 2025-08-26
An efficient technique of computing on encrypted data allows a client with
limited capability to perform complex operations on a remote fault-tolerant
server without leaking anything about the input or output. Quantum computing
provides information-theoretic security to solve such a problem, and many such
techniques have been proposed under the premises of half-blind quantum
computation. However, ...
Efficient Preparation of Resource States for Hamiltonian Simulation and Universal Quantum Computation
Thierry N. Kaldenbach, Isaac D. Smith, Hendrik Poulsen Nautrup, Matthias Heller, Hans J. Briegel • Published: 2025-09-05
The direct compilation of algorithm-specific graph states in
measurement-based quantum computation (MBQC) can lead to resource reductions in
terms of circuit depth, entangling gates, and even the number of physical
qubits. In this work, we extend previous studies on algorithm-tailored graph
states to periodic sequences of generalized Pauli rotations, which commonly
appear in, e.g., Trotterized Ham...
Quantum circuit compilation with quantum computers
Davide Rattacaso, Daniel Jaschke, Marco Ballarin, Ilaria Siloi, Simone Montangero • Published: 2024-07-31
Compilation optimizes quantum algorithms performances on real-world quantum
computers. To date, it is performed via classical optimization strategies. We
introduce a class of quantum algorithms to perform compilation via quantum
computers, paving the way for a quantum advantage in compilation. We
demonstrate the effectiveness of this approach via Quantum and Simulated
Annealing-based compilation: ...
Quantum Computing Tools for Fast Detection of Gravitational Waves in the Context of LISA Space Mission
Maria-Catalina Isfan, Laurentiu-Ioan Caramete, Ana Caramete, Daniel Tonoiu, Alexandru Nicolin-Zaczek • Published: 2025-09-16
The field of gravitational wave (GW) detection is progressing rapidly, with
several next-generation observatories on the horizon, including LISA. GW data
is challenging to analyze due to highly variable signals shaped by source
properties and the presence of complex noise. These factors emphasize the need
for robust, advanced analysis tools. In this context, we have initiated the
development of a ...
Quantum Computing Beyond Ground State Electronic Structure: A Review of Progress Toward Quantum Chemistry Out of the Ground State
Alan Bidart, Prateek Vaish, Tilas Kabengele, Yaoqi Pang, Yuan Liu, Brenda M. Rubenstein • Published: 2025-09-24
Quantum computing offers the promise of revolutionizing quantum chemistry by
enabling the solution of chemical problems for substantially less computational
cost. While most demonstrations of quantum computation to date have focused on
resolving the energies of the electronic ground states of small molecules, the
field of quantum chemistry is far broader than ground state chemistry; equally
import...
A vapor-cavity-QED system for quantum computation and communication
Sharoon Austin, Dhruv Devulapalli, Khoi Hoang, Feng Zhou, Kartik Srinivasan, Alexey V. Gorshkov • Published: 2025-09-23
In this work, we propose performing key operations in quantum computation and
communication using room-temperature atoms moving across a grid of
high-quality-factor, small-mode-volume cavities. These cavities enable
high-cooperativity interactions with single atoms to be achieved with a
characteristic timescale much shorter than the atomic transit time, allowing
multiple coherent operations to tak...
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 Hilaire • Published: 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. Briegel • Published: 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 Sacha • Published: 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...

Enhancing Targeted Adversarial Attacks on Large Vision-Language Models via Intermediate Projector
Yiming Cao, Yanjie Li, Kaisheng Liang, Bin Xiao • Published: 2025-08-19
The growing deployment of Large Vision-Language Models (VLMs) raises safety
concerns, as adversaries may exploit model vulnerabilities to induce harmful
outputs, with targeted black-box adversarial attacks posing a particularly
severe threat. However, existing methods primarily maximize encoder-level
global similarity, which lacks the granularity for stealthy and practical
fine-grained attacks, wh...
Context-aware gate set tomography: Improving the self-consistent characterization of trapped-ion universal gate sets by leveraging non-Markovianity
Pablo Viñas, Alejandro Bermudez • Published: 2025-07-03
To progress in the characterization of noise for current quantum computers,
gate set tomography (GST) has emerged as a self-consistent tomographic protocol
that can accurately estimate the complete set of noisy quantum gates, state
preparations, and measurements. In its original incarnation, GST improves the
estimation precision by applying the gates sequentially, provided that the
noise makes the...
A Quantum Algorithm For Computing Contextuality Bounds
Colm Kelleher, Frédéric Holweck • Published: 2025-09-24
Quantum contextuality is a limitation on deterministic hidden variable
models, testable in measurement scenarios where outcomes differ under quantum
or classical descriptions due to a common set of constraints. When considering
measurements of $N$-qubit spin operators, constraints arise from commutation
relations and classical bounds are determined by the $\textit{degree}$ of
contextuality, an NP-...
A Comparison of Quadratic and Higher-Order Representations for QAOA
Kristina Bell, Adam Lowe, Emily Coles, Nathanael Ridgway, Gillian Marshall • Published: 2025-09-24
In this work we consider a routing problem and compare quadratic and
higher-order representations using the Quantum Approximate Optimisation
Algorithm (QAOA). The majority of works investigating QAOA use quadratic
Hamiltonians to represent the considered problems, which can lead to poor
scaling in qubit requirements. We address the gap of direct comparisons between
quadratic and higher-order forms...
Quantum dual extended Hamming code immune to collective coherent errors
En-Jui Chang • Published: 2025-03-07
Collective coherent (CC) errors are inevitable, as every physical qubit
undergoes free evolution under its kinetic Hamiltonian. These errors can be
more damaging than stochastic Pauli errors because they affect all qubits
coherently, resulting in high-weight errors that standard quantum
error-correcting (QEC) codes struggle to correct. In quantum memories and
communication systems, especially when...
Rapid Autotuning of a SiGe Quantum Dot into the Single-Electron Regime with Machine Learning and RF-Reflectometry FPGA-Based Measurements
Marc-Antoine Roux, Joffrey Rivard, Victor Yon, Alexis Morel, Dominic Leclerc, Claude Rohrbacher, El Bachir Ndiaye, Felice Francesco Tafuri, Brendan Bono, Stefan Kubicek, Roger Loo, Yosuke Shimura, Julien Jussot, Clément Godfrin, Danny Wan, Kristiaan De Greve, Marc-André Tétrault, Dominique Drouin, Christian Lupien, Michel Pioro-Ladrière, Eva Dupont-Ferrier • Published: 2025-09-23
Spin qubits need to operate within a very precise voltage space around charge
state transitions to achieve high-fidelity gates. However, the stability
diagrams that allow the identification of the desired charge states are long to
acquire. Moreover, the voltage space to search for the desired charge state
increases quickly with the number of qubits. Therefore, faster stability
diagram acquisitions...
Semantic-Aware Fuzzing: An Empirical Framework for LLM-Guided, Reasoning-Driven Input Mutation
Mengdi Lu, Steven Ding, Furkan Alaca, Philippe Charland • Published: 2025-09-23
Security vulnerabilities in Internet-of-Things devices, mobile platforms, and
autonomous systems remain critical. Traditional mutation-based fuzzers -- while
effectively explore code paths -- primarily perform byte- or bit-level edits
without semantic reasoning. Coverage-guided tools such as AFL++ use
dictionaries, grammars, and splicing heuristics to impose shallow structural
constraints, leaving...
