−A recipe for local simulation of strongly-correlated fermionic matter on quantum computers: the 2D Fermi-Hubbard model
Arash Jafarizadeh, Frank Pollmann, Adam Gammon-Smith • Published: 2024-08-26
The simulation of quantum many-body systems, relevant for quantum chemistry
and condensed matter physics, is one of the most promising applications of
near-term quantum computers before fault-tolerance. However, since the vast
majority of quantum computing technologies are built around qubits and discrete
gate-based operations, the translation of the physical problem into this
framework is a cruci...
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-Żaczek • 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 ...

Viviana Centritto, Ama Bandara, Heqi Deng, Masoud Babaie, Evgenii Vinogradov, Sergi Abadal, Eduard Alarcon • Published: 2025-10-15
Scaling quantum computers from a few qubits to large numbers remains one of
the critical challenges in realizing practical quantum advantage. Multi-core
quantum architectures have emerged as a promising solution, enabling
scalability through distributed quantum processing units (QPUs) interconnected
via classical and quantum links. However, the bottleneck of wired connections
persists, as densely ...
Emergent Discrete Time Crystals on Digital Quantum Computers: Boundary-Protected and Ancilla-Induced Disorder Mechanisms of Thermalization Slowdown
Kazuya Shinjo, Kazuhiro Seki, Seiji Yunoki • Published: 2025-10-15
Periodically driven (Floquet) systems typically evolve toward an
infinite-temperature thermal state due to continuous energy absorption. Before
reaching equilibrium, however, they can transiently exhibit long-lived
prethermal states that host exotic nonequilibrium phenomena, such as discrete
time crystals (DTCs). In this study, we investigate the relaxation dynamics of
periodically driven product ...
State-Specific Orbital Optimization for Enhanced Excited-States Calculation on Quantum Computers
Guorui Zhu, Joel Bierman, Jianfeng Lu, Yingzhou Li • Published: 2025-10-15
We propose a state-specific orbital optimization scheme for improving the
accuracy of excited states of the electronic structure Hamiltonian for the use
on near-term quantum computers, which can be combined with any overlap-based
excited-state quantum eigensolver. We derived the gradient of the overlap term
between different states generated by different orbitals with respect to the
orbital rotati...
Lattice surgery with Bell measurements: Modular fault-tolerant quantum computation at low entanglement cost
Trond Hjerpekjøn Haug, Timo Hillmann, Anton Frisk Kockum, Raphaël Van Laer • Published: 2025-10-15
Modular architectures are a promising approach to scaling quantum computers
to fault tolerance. Small, low-noise quantum processors connected through
relatively noisy quantum links are capable of fault-tolerant operation as long
as the noise can be confined to the interface. Finding protocols that implement
the quantum links between modules as efficiently as possible is essential
because inter-mod...
Performance Comparison of Gate-Based and Adiabatic Quantum Computing for Power Flow Analysis
Zeynab Kaseb, Matthias Moller, Peter Palensky, Pedro P. Vergara • Published: 2025-10-15
In this paper, we present the first direct comparison between gate-based
quantum computing (GQC) and adiabatic quantum computing (AQC) for solving the
AC power flow (PF) equations. Building on the Adiabatic Quantum Power Flow
(AQPF) algorithm originally designed for annealing platforms, we adapt it to
the Quantum Approximate Optimization Algorithm (QAOA). The PF equations are
reformulated as a com...
A low-circuit-depth quantum computing approach to the nuclear shell model
Chandan Sarma, Paul Stevenson • Published: 2025-10-02
In this work, we introduce a new qubit mapping strategy for the Variational
Quantum Eigensolver (VQE) applied to nuclear shell model calculations, where
each Slater determinant (SD) is mapped to a qubit, rather than assigning qubits
to individual single-particle states. While this approach may increase the
total number of qubits required in some cases, it enables the construction of
simpler quantu...
Privacy-Aware Framework of Robust Malware Detection in Indoor Robots: Hybrid Quantum Computing and Deep Neural Networks
Tan Le, Van Le, Sachin Shetty • Published: 2025-10-15
Indoor robotic systems within Cyber-Physical Systems (CPS) are increasingly
exposed to Denial of Service (DoS) attacks that compromise localization,
control and telemetry integrity. We propose a privacy-aware malware detection
framework for indoor robotic systems, which leverages hybrid quantum computing
and deep neural networks to counter DoS threats in CPS, while preserving
privacy information. ...
Trajectory-Protected Quantum Computing
Barbara Šoda, Pierre-Antoine Graham, T. Rick Perche, Gurpahul Singh • Published: 2025-10-14
We introduce a novel method that simultaneously isolates a quantum computer
from decoherence and enables the controlled implementation of computational
gates. We demonstrate a quantum computing model that utilizes a qubit's motion
to protect it from decoherence. We model a qubit interacting with a quantum
field via the standard light-matter interaction model: an Unruh-DeWitt
detector, i.e., the qu...

Migrating codebases from one instruction set architecture (ISA) to another is
a major engineering challenge. A recent example is the adoption of Arm (in
addition to x86) across the major Cloud hyperscalers. Yet, this problem has
seen limited attention by the academic community. Most work has focused on
static and dynamic binary translation, and the traditional conventional wisdom
has been that thi...
A Performance Portable Matrix Free Dense MTTKRP in GenTen
Gabriel Kosmacher, Eric T. Phipps, Sivasankaran Rajamanickam • Published: 2025-10-16
We extend the GenTen tensor decomposition package by introducing an
accelerated dense matricized tensor times Khatri-Rao product (MTTKRP), the
workhorse kernel for canonical polyadic (CP) tensor decompositions, that is
portable and performant on modern CPU and GPU architectures. In contrast to the
state-of-the-art matrix multiply based MTTKRP kernels used by Tensor Toolbox,
TensorLy, etc., that ex...

Naeimeh Mohseni, Thomas Morstyn, Corey O'Meara, David Bucher, Jonas Nüßlein, Giorgio Cortiana • Published: 2024-05-20
The formation of energy communities is pivotal for advancing decentralized
and sustainable energy management. Within this context, Coalition Structure
Generation (CSG) emerges as a promising framework. The complexity of CSG grows
rapidly with the number of agents, making classical solvers impractical for
even moderate sizes. This suggests CSG as an ideal candidate for benchmarking
quantum algorith...
Signatures of Topological Symmetries on a Noisy Quantum Simulator
Christopher Lamb, Robert M. Konik, Hubert Saleur, Ananda Roy • Published: 2025-10-16
Topological symmetries, invertible and otherwise, play a fundamental role in
the investigation of quantum field theories. Despite their ubiquitous
importance across a multitude of disciplines ranging from string theory to
condensed matter physics, controlled realizations of models exhibiting these
symmetries in physical systems are rare. Quantum simulators based on engineered
solid-state devices p...
Quantifying Charge Noise Sources in Quantum Dot Spin Qubits via Impedance Spectroscopy, DLTS, and C-V Analysis
Tyafur Rahman Pathan, Daryoosh Vashaee • Published: 2025-10-12
The coherence and fidelity of quantum dot (QD) spin qubits are fundamentally
limited by charge noise arising from electrically active trap states at oxide
interfaces, heterostructure boundaries, and within the bulk semiconductor.
These traps introduce electrostatic fluctuations that couple to the qubit via
spin-orbit interactions or charge-sensitive confinement potentials, leading to
dephasing and...
Synthetic fractional flux quanta in a ring of superconducting qubits
Luca Chirolli, Juan Polo, Gianluigi Catelani, Luigi Amico • Published: 2024-09-10
A ring of capacitively coupled transmons threaded by a synthetic magnetic
field is studied as a realization of a strongly interacting bosonic system. The
synthetic flux is imparted through a specific Floquet modulation scheme based
on a suitable periodic sequence of Lorentzian pulses that are known as
'Levitons'. Such scheme has the advantage to preserve the translation
invariance of the system an...
AEX-NStep: Probabilistic Interrupt Counting Attacks on Intel SGX
Nicolas Dutly, Friederike Groschupp, Ivan Puddu, Kari Kostiainen, Srdjan Capkun • Published: 2025-10-16
To mitigate interrupt-based stepping attacks (notably using SGX-Step), Intel
introduced AEX-Notify, an ISA extension to Intel SGX that aims to prevent
deterministic single-stepping. In this work, we introduce AEX-NStep, the first
interrupt counting attack on AEX-Notify-enabled Enclaves. We show that
deterministic single-stepping is not required for interrupt counting attacks to
be practical and th...

Rémi Pasquier, María Camarasa-Gómez, Anna-Sophia Hehn, Daniel Hernangómez-Pérez, Jan Wilhelm • Published: 2025-07-24
We present a $GW$ space-time algorithm for periodic systems in a Gaussian
basis including spin-orbit coupling. We employ lattice summation to compute the
irreducible density response and the self-energy, while we employ $k$-point
sampling for computing the screened Coulomb interaction. Our algorithm enables
accurate and computationally efficient quasiparticle band structure
calculations for atomic...
