−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...

On the Potential of Quantum Computing in Classical Program Analysis
Yicheng Guang, Pietro Zanotta, Kai Zhou, Yueqi Chen, Ramin Ayanzadeh • Published: 2025-10-13
Classical program analysis techniques, such as abstract interpretation and
symbolic execution, are essential for ensuring software correctness, optimizing
performance, and enabling compiler optimizations. However, these techniques
face computational limitations when analyzing programs with large or
exponential state spaces, limiting their effectiveness in ensuring system
reliability. Quantum compu...
Error mitigation for partially error-corrected quantum computers
Ben DalFavero, Ryan LaRose • Published: 2025-10-13
We present a method for quantum error mitigation on partially error-corrected
quantum computers - i.e., computers with some logical qubits and some noisy
qubits. Our method is inspired by the error cancellation method and is
implemented via a circuit for convex combinations of channels which we
introduce in this work. We show how logical ancilla qubits can arbitrarily
reduce the sampling complexit...

Quantum systems have started to emerge as a disruptive technology and
enabling platforms - exploiting the principles of quantum mechanics via
programmable quantum bits (QuBits) - to achieve quantum supremacy in computing.

Enhancing quantum computations with the synergy of auxiliary field quantum Monte Carlo and computational basis tomography
Viktor Khinevich, Wataru Mizukami • Published: 2025-02-27
We introduce QC-CBT-AFQMC, a hybrid algorithm that incorporates computational
basis tomography (CBT) into the quantum-classical auxiliary-field quantum Monte
Carlo (QC-AFQMC) method proposed by Huggins et al. [Nature 603, 416-420
(2022)], replacing the use of classical shadows. While the original QC-AFQMC
showed high accuracy for quantum chemistry calculations, it required
exponentially costly pos...
Random State Approach to Quantum Computation of Electronic-Structure Properties
Yiran Bai, Feng Xiong, Xueheng Kuang • Published: 2025-10-11
Classical computation of electronic properties in large-scale materials
remains challenging. Quantum computation has the potential to offer advantages
in memory footprint and computational scaling. However, general and practical
quantum algorithms for simulating large-scale materials are still lacking. We
propose and implement random-state quantum algorithms to calculate
electronic-structure prope...

Zhichao Guo, Rik A. H. van Herk, Edgar J. D. Vredenbregt, Servaas J. J. M. F. Kokkelmans • Published: 2025-10-10
We present a novel acousto-optic lens (AOL) design for neutral atom quantum
computing. This approach enhances atom rearrangement in optical tweezer arrays
and addresses the speed limitations imposed by the cylindrical lensing effect
of acousto-optic deflectors (AODs). By combining a double-pass AOD
configuration for dynamic focal tuning with a standard pair of crossed AODs for
transverse beam stee...
On Quantum Computation Using Bias-Preserving Gates
Debadrito Roy, Aryaman Manish Kolhe, V. Lalitha, Navin Kashyap • Published: 2025-10-08
Certain types of quantum computing platforms, such as those realized using
Rydberg atoms or Kerr-cat qubits, are natively more susceptible to Pauli-Z
noise than Pauli-X noise, or vice versa. On such hardware, it is useful to
ensure that computations use only gates that maintain the Z-bias (or X-bias) in
the noise. This is so that quantum error-correcting codes tailored for
biased-noise models can ...

Sauro Succi, Claudio Sanavio, Peter Love • Published: 2025-10-10
Quantum algorithms for classical physics problems expose new patterns of
quantum information flow as compared to the many-body Schr\"{o}dinger equation.
As a result, besides their potential practical applications, they also offer a
valuable theoretical and computational framework to elucidate the foundations
of quantum mechanics, particularly the validity of the many-body
Schr\"{o}dinger equation ...

−A GPU-resident Memory-Aware Algorithm for Accelerating Bidiagonalization of Banded Matrices
Evelyne Ringoot, Rabab Alomairy, Alan Edelman • Published: 2025-10-14
The reduction of a banded matrix to a bidiagonal form is a crucial step in
the Singular Value Decomposition (SVD), a cornerstone of scientific computing
and AI. Despite being a highly parallel algorithm, it was previously believed
to be unsuitable for GPU computation because it is memory bandwidth-bound.
Recent developments in GPU hardware, including larger L1 memory per Streaming
Multiprocessor/C...
Proof of Cloud: Data Center Execution Assurance for Confidential VMs
Filip Rezabek, Moe Mahhouk, Andrew Miller, Stefan Genchev, Quintus Kilbourn, Georg Carle, Jonathan Passerat-Palmbach • Published: 2025-10-14
Confidential Virtual Machines (CVMs) protect data in use by running workloads
inside hardware-isolated environments. In doing so, they also inherit the
limitations of the underlying hardware. Trusted Execution Environments (TEEs),
which enforce this isolation, explicitly exclude adversaries with physical
access from their threat model. Commercial TEEs, e.g., Intel TDX, thus assume
infrastructure p...
Experimental verification of multi-copy activation of genuine multipartite entanglement
Robert Stárek, Tim Gollerthan, Olga Leskovjanová, Michael Meth, Peter Tirler, Nicolai Friis, Martin Ringbauer, Ladislav Mišta Jr • Published: 2025-10-14
A central concept in quantum information processing is genuine multipartite
entanglement (GME), a type of correlation beyond biseparability, that is,
correlations that cannot be explained by statistical mixtures of partially
separable states. GME is relevant for characterizing and benchmarking complex
quantum systems, and it is an important resource for applications such as
quantum communication. ...
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...

Benzheng Yuan, Chaojie Zhang, Chuanbing Han, Shuya Wang, Peng Xu, Huihui Sun, Qing Mu, Lixin Wang, Bo Zhao, Weilong Wang, Zheng Shan • Published: 2025-10-10
In superconducting quantum circuits, decoherence errors in qubits constitute
a critical factor limiting quantum gate performance. To mitigate
decoherence-induced gate infidelity, rapid implementation of quantum gates is
essential. Here we propose a scheme for rapid controlled-Z (CZ) gate
implementation through energy-level engineering, which leverages Rabi
oscillations between the |11> state and t...
An Empirical Study of Reducing AV1 Decoder Complexity and Energy Consumption via Encoder Parameter Tuning
Vibhoothi Vibhoothi, Julien Zouein, Shanker Shreejith, Jean-Baptiste Kempf, Anil Kokaram • Published: 2025-10-14
The widespread adoption of advanced video codecs such as AV1 is often
hindered by their high decoding complexity, posing a challenge for
battery-constrained devices. While encoders can be configured to produce
bitstreams that are decoder-friendly, estimating the decoding complexity and
energy overhead for a given video is non-trivial. In this study, we
systematically analyse the impact of disablin...
