−Edge modes, extended TQFT, and measurement based quantum computation
Gabriel Wong • Published: 2023-12-01
Quantum teleportation can be used to define a notion of parallel transport
which characterizes the entanglement structure of a quantum state
\cite{Czech:2018kvg}. This suggests one can formulate a gauge theory of
entanglement. In \cite{Wong:2022mnv}, it was explained that measurement based
quantum computation in one dimension can be understood in term of such a gauge
theory (MBQC). In this work, w...
Solving Free Fermion Problems on a Quantum Computer
Maarten Stroeks, Daan Lenterman, Barbara Terhal, Yaroslav Herasymenko • Published: 2024-09-06
Simulating noninteracting fermion systems is a common task in computational
many-body physics. In absence of translational symmetries, modeling free
fermions on $N$ modes usually requires poly$(N)$ computational resources. While
often moderate, these costs can be prohibitive in practice when large systems
are considered. We present several free-fermion problems that can be solved by
a quantum algo...
Towards reconstructing quantum structured light on a quantum computer
Mwezi Koni, Shawal Kasim, Paola C. Obando, Neelan Gounden, Isaac Nape • Published: 2025-09-26
We introduce a variational quantum computing approach for reconstructing
quantum states from measurement data. By mapping the reconstruction cost
function onto an Ising model, the problem can be solved using a variational
eigensolver on present-day quantum hardware. As a proof of concept, we
demonstrate the method on quantum structured light, in particular, entangled
photons carrying orbital angul...
Quantum Computer Fingerprinting using Error Syndromes
Vincent Mutolo, Devon Campbell, Quinn Manning, Henri Witold Dubourg, Ruibin Lyu, Simha Sethumadhavan, Daniel Rubenstein, Salvatore Stolfo • Published: 2025-06-19
As quantum computing matures and moves toward broader accessibility through
cloud-based platforms, ensuring the authenticity and integrity of quantum
computations becomes an urgent concern. In this work, we propose a strategy to
leverage the byproducts of quantum error correction (QEC) to verify hardware
identity and authenticate quantum computations for "free", without introducing
any additional ...
Scalable modular architecture for universal quantum computation
Fernando Gago-Encinas, Christiane P. Koch • Published: 2025-07-19
Universal quantum computing requires the ability to perform every unitary
operation, i.e., evolution operator controllability. In view of developing
resource-efficient quantum processing units (QPUs), it is important to
determine how many local controls and qubit-qubit couplings are required for
controllability. Unfortunately, assessing the controllability of large qubit
arrays is a difficult task...
Benchmarking Quantum Computers: Towards a Standard Performance Evaluation Approach
Arturo Acuaviva, David Aguirre, Rubén Peña, Mikel Sanz • Published: 2024-07-15
The technological development of increasingly larger quantum processors on
different quantum platforms raises the problem of how to fairly compare their
performance, known as quantum benchmarking of quantum processors. This is a
challenge that computer scientists have already faced when comparing classical
processors, leading to the development of various mathematical tools to address
it, but also...

We report accurate quantum simulations of medium-mass atomic nuclei
-including oxygen, calcium, and nickel- on the RIKEN-Quantinuum Reimei
trapped-ion quantum computer, achieving sub-percent accuracy. Using a
symmetry-aware pair-unitary coupled-cluster doubles (pUCCD) ansatz implemented
with a hard-core-boson mapping, and with particle-number-restoring
post-selection, our ground-state energy estim...

Emil Otis Rosanowski, Arianna Crippa, Lena Funcke, Paulo Vitor Itaborai, Karl Jansen, Simran Singh • Published: 2025-09-24
In this paper, we explore (2+1)D quantum electrodynamics (QED) at finite
density on a quantum computer, including two fermion flavors. Our method
employs an efficient gauge-invariant ansatz together with a quantum circuit
structure that enforces Gauss's law. As a proof of principle, we benchmark our
simulation protocol on a small lattice system, demonstrating the identification
of phase transition...
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...

−Probing Fractional Quantum Hall states in weakly interacting Fermi gases
Viktor Bekassy, Mikael Fogelström, Johannes Hofmann • Published: 2025-09-26
Quantum gases are used to simulate the physics of the lowest Landau level
(LLL) with neutral atoms, which in the simplest setup is achieved by rotating
the gas at the confining harmonic trap frequency, a requirement that is
difficult to achieve in practice. We point out that for weakly interacting
Fermi gases, this rapid-rotation limit is not needed to access the LLL: As a
direct consequence of fi...
Laughlin-like states of few atomic excitations in small subwavelength atom arrays
Błażej Jaworowski, Darrick E. Chang • Published: 2025-04-23
Atom arrays with sub-wavelength lattice constant can exhibit fascinating
optical properties. For example, the combination of $V$-type level structure
and magnetic fields can yield topological band structures, making the neutral
atomic excitations behave like charged particles in a magnetic field. Up to
now, much of our understanding of these systems (and arrays in general) focuses
on the single-ex...

Hisham Abdelqader • Published: 2025-08-09
As video games continue to evolve, understanding what drives player enjoyment
remains a key challenge. Player reviews provide valuable insights, but their
unstructured nature makes large-scale analysis difficult. This study applies
generative AI and machine learning, leveraging Microsoft Phi-4 small language
model (SLM) and Google Cloud, to quantify and analyze game reviews from Steam
and Meta Que...

Davide G. F. Lombardo, Siddharth Gautam, Alberto Ferraris, Manuel Le Gallo, Abu Sebastian, Ghazi Sarwat Syed • Published: 2025-09-26
In-memory computing (IMC) is an emerging non-von Neumann paradigm that
leverages the intrinsic physics of memory devices to perform computations
directly within the memory array. Among the various candidates, phase-change
memory (PCM) has emerged as a leading non-volatile technology, showing
significant promise for IMC, particularly in deep learning acceleration.
PCM-based IMC is also poised to pl...

In an era dominated by Large Language Models (LLMs), understanding their
capabilities and limitations, especially in high-stakes fields like law, is
crucial. While LLMs such as Meta's LLaMA, OpenAI's ChatGPT, Google's Gemini,
DeepSeek, and other emerging models are increasingly integrated into legal
workflows, their performance in multilingual, jurisdictionally diverse, and
adversarial contexts re...

Meta Mapillary enable users to virtually navigate and experience real-world
environments via immersive 360{\deg} imagery but remain fundamentally
inaccessible to blind users. We introduce StreetReaderAI, the first-ever
accessible street view tool, which combines context-aware, multimodal AI,
accessible navigation controls, ...
Structured Sparse Transition Matrices to Enable State Tracking in State-Space Models
Aleksandar Terzić, Nicolas Menet, Michael Hersche, Thomas Hofmann, Abbas Rahimi • Published: 2025-09-26
Modern state-space models (SSMs) often utilize transition matrices which
enable efficient computation but pose restrictions on the model's expressivity,
as measured in terms of the ability to emulate finite-state automata (FSA).
While unstructured transition matrices are optimal in terms of expressivity,
they come at a prohibitively high compute and memory cost even for moderate
state sizes. We pr...
Introduction of modelling radical pair quantum spin dynamics with tensor networks
Kentaro Hino, Damyan S. Frantzov, Yuki Kurashige, Lewis M. Antill • Published: 2025-09-26
Radical pairs (also known as spin qubit pairs, electron-hole pairs) are
transient reaction intermediates that are found and utilised in all areas of
science. Radical pair spin dynamics simulations including all nuclear spins
have been a computational barrier due to exponential scaling memory
requirements. We address this issue with a tensor network method for accurately
simulating the full open qu...
