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...

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 ...
The foundational value of quantum computing for classical fluids
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 ...
Gate Teleportation vs Circuit Cutting in Distributed Quantum Computing
Shobhit Gupta, Nikolay Sheshko, Daniel J. Dilley, Alvin Gonzales, Manish K. Singh, Zain H. Saleem • Published: 2025-10-10
Distributing circuits across quantum processor modules will enable the
execution of circuits larger than the qubit count limitations of monolithic
processors. While distributed quantum computation has primarily utilized
circuit cutting, it incurs an exponential growth of sub-circuit sampling and
classical post-processing overhead with an increasing number of cuts. The
entanglement-based gate telep...

numerically, in particular, in hig...
Characterizing Web Search in The Age of Generative AI
Elisabeth Kirsten, Jost Grosse Perdekamp, Mihir Upadhyay, Krishna P. Gummadi, Muhammad Bilal Zafar • Published: 2025-10-13
The advent of LLMs has given rise to a new type of web search: Generative
search, where LLMs retrieve web pages related to a query and generate a single,
coherent text as a response. This output modality stands in stark contrast to
traditional web search, where results are returned as a ranked list of
independent web pages. In this paper, we ask: Along what dimensions do
generative search outputs ...

Superconducting qubits equipped with quantum non-demolition readout and
active feedback can be used as information engines to probe and manipulate
microscopic degrees of freedom, whether intentionally designed or naturally

magnetic field bias presents a challenge for superconductors and Josephson
junctions. Here we demonstra...
Astigmatism-free 3D Optical Tweezer Control for Rapid Atom Rearrangement
Yue-Hui Lu, Nathan Song, Tai Xiang, Jacquelyn Ho, Tsai-Chen Lee, Zhenjie Yan, Dan M. Stamper-Kurn • Published: 2025-10-13
Reconfigurable arrays of neutral atoms are a leading platform for quantum
computing, quantum simulation, and quantum metrology. The most common method
for atom reconfiguration using optical tweezers relies on frequency chirping of
acousto-optic deflectors (AODs). However, chirp-induced acoustic lensing limits
the speed of atom transport by deformation of the tweezer profile and warping
of the twee...

We present an experimental implementation of the Pusey-Barrett-Rudolph (PBR)
no-go theorem on IBM's 156-qubit Heron2 Marrakesh superconducting quantum
processor. By preparing qubits in a set of non-orthogonal states and evolving
them under carefully compiled unitary circuits, we test whether one can
interpret the hidden variable model for quantum states as merely epistemic --
reflecting ignorance ...
Tensor-Network-Based Unraveling of Non-Markovian Dynamics in Large Spin Chains via the Influence Martingale Approach
Sujay Mondal, Siddhartha Dutta, Abhijit Bandyopadhyay • Published: 2025-10-13
Classical simulation of open quantum system dynamics remains challenging due
to the exponential growth of the Hilbert space, the need to accurately capture
dissipation and decoherence, and the added complexity of memory effects in the
non-Markovian regime. We develop an efficient algorithm for simulating both
Markovian and non-Markovian dynamics in large one-dimensional quantum systems.
