−Reproducible Builds for Quantum Computing
Iyán Méndez Veiga, Esther Hänggi • Published: 2025-10-02
Reproducible builds are a set of software development practices that
establish an independently verifiable path from source code to binary
artifacts, helping to detect and mitigate certain classes of supply chain
attacks. Although quantum computing is a rapidly evolving field of research, it
can already benefit from adopting reproducible builds. This paper aims to
bridge the gap between the quantu...
Hamiltonian simulation-based quantum-selected configuration interaction for large-scale electronic structure calculations with a quantum computer
Kenji Sugisaki, Shu Kanno, Toshinari Itoko, Rei Sakuma, Naoki Yamamoto • Published: 2024-12-10
Quantum-selected configuration interaction (QSCI) is an approach for quantum
chemical calculations using current quantum computers. In conventional QSCI,
Slater determinants used for the wave function expansion are sampled by
iteratively performing approximate wave function preparation and subsequent
measurement in the computational basis, and then the subspace Hamiltonian
matrix is diagonalized o...

Yuqian Huo, Jinbiao Wei, Christopher Kverne, Mayur Akewar, Janki Bhimani, Tirthak Patel • Published: 2025-07-01
Transpilation, particularly noise-aware optimization, is widely regarded as
essential for maximizing the performance of quantum circuits on superconducting
quantum computers. The common wisdom is that each circuit should be transpiled
using up-to-date noise calibration data to optimize fidelity. In this work, we
revisit the necessity of frequent noise-adaptive transpilation, conducting an
in-depth...
Photonic Hybrid Quantum Computing
Jaehak Lee, Srikrishna Omkar, Yong Siah Teo, Seok-Hyung Lee, Hyukjoon Kwon, M. S. Kim, Hyunseok Jeong • Published: 2025-10-01
Photons are a ubiquitous carrier of quantum information: they are fast,
suffer minimal decoherence, and do not require huge cryogenic facilities.
Nevertheless, their intrinsically weak photon-photon interactions remain a key
obstacle to scalable quantum computing. This review surveys hybrid photonic
quantum computing, which exploits multiple photonic degrees of freedom to
combine the complementary...
Exploiting Translational Symmetry for Quantum Computing with Squeezed Cat Qubits
Tomohiro Shitara, Gabriel Mintzer, Yuuki Tokunaga, Suguru Endo • Published: 2025-10-01
Squeezed cat quantum error correction (QEC) codes have garnered attention
because of their robustness against photon-loss and excitation errors while
maintaining the biased-noise property of cat codes. In this work, we reveal the
utility of the unexplored translational symmetry of the squeezed cat codes,
with applications to autonomous QEC, reliable logical operations, and readout
in a non-orthogo...
Estimating quantum relative entropies on quantum computers
Yuchen Lu, Kun Fang • Published: 2025-01-13
Quantum relative entropy, a quantum generalization of the renowned
Kullback-Leibler divergence, serves as a fundamental measure of the
distinguishability between quantum states and plays a pivotal role in quantum
information science. Despite its importance, efficiently estimating quantum
relative entropy between two quantum states on quantum computers remains a
significant challenge. In this work,...

Matthias Deiml, Daniel Peterseim • Published: 2024-11-25
This paper presents a novel framework for high-dimensional nonlinear quantum
computation that exploits tensor products of amplified vector and matrix
encodings to efficiently evaluate multivariate polynomials. The approach
enables the solution of nonlinear equations by quantum implementations of the
fixed-point iteration and Newton's method, with quantitative runtime bounds
derived in terms of the...
Measurement-based quantum computation using two-component BECs
Genji Fujii • Published: 2022-03-16
In this paper, we propose measurement-based quantum computation (MBQC) using
two-component Bose-Einstein condensates (BECs). Graph states are naturally
introduced by analogy
with the qubit case. An arbitrary state of one logical qubit can be obtained
through a three-body
measurement. Furthermore, we propose methods for implementing CZ gates on the
components of
coherent states of BECs in a g...

The intersection of quantum computing and quantum chemistry represents a
promising frontier for achieving quantum utility in domains of both scientific
and societal relevance. Owing to the exponential growth of classical resource
requirements for simulating quantum systems, quantum chemistry has long been
recognized as a natural candidate for quantum computation. This perspective
focuses on identi...
Fast quantum computation with all-to-all Hamiltonians
Chao Yin • Published: 2025-09-29
All-to-all interactions arise naturally in many areas of theoretical physics
and across diverse experimental quantum platforms, motivating a systematic
study of their information-processing power. Assuming each pair of qubits
interacts with $\mathrm{O}(1)$ strength, time-dependent all-to-all Hamiltonians
can simulate arbitrary all-to-all quantum circuits, performing quantum
computation in time pro...

−Quantum simulation of nuclear shell model: bridging theory and hardware limitations
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...
The Current State of AI Bias Bounties: An Overview of Existing Programmes and Research
Sergej Kucenko, Nathaniel Dennler, Fengxiang He • Published: 2025-10-02
Current bias evaluation methods rarely engage with communities impacted by AI
systems. Inspired by bug bounties, bias bounties have been proposed as a
reward-based method that involves communities in AI bias detection by asking
users of AI systems to report biases they encounter when interacting with such
systems. In the absence of a state-of-the-art review, this survey aimed to
identify and analy...

Ben Rosenzweig, Valentino Dalla Valle, Giovanni Apruzzese, Aurore Fass • Published: 2025-09-25
Google Chrome is the most popular Web browser. Users can customize it with
extensions that enhance their browsing experience. The most well-known
marketplace of such extensions is the Chrome Web Store (CWS). Developers can
upload their extensions on the CWS, but such extensions are made available to
users only after a vetting process carried out by Google itself. Unfortunately,
some malicious exte...

Simulating nonequilibrium dynamics of quantum many-body systems is one of the
most promising applications of quantum computers. However, a faithful digital
quantum simulation of the Hamiltonian evolution is very challenging in the
present noisy quantum devices. Instead, nonequilibrium dynamics under the
Floquet evolution realized by the Trotter decomposition of the Hamiltonian
evolution with a lar...

We analyze the implementation of high-fidelity, phonon-mediated gate
operations and quantum simulation schemes for spin qubits associated with
silicon vacancy centers in diamond. Specifically, we show how the application
of continuous dynamical decoupling techniques can substantially boost the
coherence of the qubit states while increasing at the same time the variety of
effective spin models that...

We report on the internal quality factor of a three-dimensional niobium
quarter-wave coaxial cavity, with mid-temperature annealing, exhibiting $Q_{\rm
int} \gtrsim 3\times10^9$ at the single-photon level below 20\,mK, which
corresponds to an internal photon lifetime of $\tau_{\rm
