−Nonlinear quantum computation by amplified encodings
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...

Significant advances in silicon spin qubits highlight the potential of
silicon quantum dots for scalable quantum computing, given their compatibility
with industrial fabrication and long coherence times. In particular, phosphorus
(P)-doped spin qubits possess excellent coherence and have demonstrated
high-fidelity two-qubit gates exceeding 99.9%. However, scaling P-donor systems
is challenging due...

Anticoherent $k$-planes and coding techniques for a 3-qubit scheme of universal quantum computing
L. Aragón-Muñoz, C. Chryssomalakos, A. G. Flores-Delgado, V. Rascón-Barajas, I. Vázquez Mota • Published: 2025-09-27
Toponomic quantum computing (TQC) employs rotation sequences of anticoherent
$k$-planes to construct noise-tolerant quantum gates. In this work, we
demonstrate the implementation of generalized Toffoli gates, using $k$-planes
of spin systems with $s \geq k + 1$, and of the Hadamard gate for a 3-qubit
system, using a spin $s \!= \! 15$ 8-plane. We propose a universal quantum
computing scheme for 3-...
Leveraging Quantum Computing For Recourse-Based Energy Management Under PV Generation Uncertainty
Daniel Müssig, Mustafa Musab, Markus Wappler, Jörg Lässig • Published: 2025-09-27
The integration of distributed energy resources, particularly photovoltaic
(PV) systems and electric vehicles (EVs), introduces significant uncertainty
and complexity into modern energy systems. This paper explores a novel approach
to address these challenges by formulating a stochastic optimization problem
that models the uncertain nature of PV power generation and the flexibility of
bi-direction...
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...

−Beyond Entanglement: Diagnosing quantum mediator dynamics in gravitationally mediated experiments
P. George Christopher, S. Shankaranarayanan • Published: 2025-06-04
No experimental test to date has provided conclusive evidence on the quantum
nature of gravity. Recent proposals, such as the BMV experiment, suggest that
generating entanglement could serve as a direct test. Motivated by these
proposals, we study a system of three-harmonic oscillator system, with the
mediator oscillator operating in two distinct parameter regimes: a heavy
mediator regime and a li...
Electrical Readout of Spin Environments in Diamond for Quantum Sensing
Olga Rubinas, Michael Petrov, Emilie Bourgeois, Jaroslav Hruby, Akhil Kuriakose, Ottavia Jedrkiewicz, Milos Nesladek • Published: 2025-09-30
Nitrogen-vacancy (NV) centres in diamond are a key platform for quantum
sensing and quantum information, combining long coherence times with
controllable spin-spin interactions. Most of current quantum algorithms rely on
optical access, which limit device integration and applicability in opaque or
miniaturized settings. Here we demonstrate an all-electrical approach,
photocurrent double electron-e...

This study presents the first large-scale, side-by-side comparison of
contemporary Large Language Models (LLMs) in the automated grading of
programming assignments. Drawing on over 6,000 student submissions collected
across four years of an introductory programming course, we systematically
analysed the distribution of grades, differences in mean scores and variability
reflecting stricter or more ...
Microwave-to-Optical Quantum Transduction of Photons for Quantum Interconnects
Akihiko Sekine, Ryo Murakami, Yoshiyasu Doi • Published: 2025-09-30
The quantum transduction, or equivalently quantum frequency conversion, is
vital for the realization of, e.g., quantum networks, distributed quantum
computing, and quantum repeaters. The microwave-to-optical quantum transduction
is of particular interest in the field of superconducting quantum computing,
since interconnecting dilution refrigerators is considered inevitable for
realizing large-scal...
EditReward: A Human-Aligned Reward Model for Instruction-Guided Image Editing
Keming Wu, Sicong Jiang, Max Ku, Ping Nie, Minghao Liu, Wenhu Chen • Published: 2025-09-30
Recently, we have witnessed great progress in image editing with natural
language instructions. Several closed-source models like GPT-Image-1, Seedream,
and Google-Nano-Banana have shown highly promising progress. However, the
open-source models are still lagging. The main bottleneck is the lack of a
reliable reward model to scale up high-quality synthetic training data. To
address this critical b...

, AMD __ , Apple __ , and Nvidia __ , considering both latency and energy
efficiency. Our results ...
