Nonlinear quantum computation by amplified encodings

Matthias Deiml, Daniel PeterseimPublished: 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 FujiiPublished: 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 YinPublished: 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 MotaPublished: 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 LässigPublished: 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 WongPublished: 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 HerasymenkoPublished: 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. ShankaranarayananPublished: 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 NesladekPublished: 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 DoiPublished: 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 ChenPublished: 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...
