−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,...
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...

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...

−Dynamic Pacing for Real-time Satellite Traffic
Aashish Gottipati, Lili Qiu • Published: 2025-07-13
Google's congestion control (GCC) has become a cornerstone for real-time
video and audio communication, yet its performance remains fragile in emerging
Low Earth Orbit (LEO) networks. In this paper, we study the behavior of
videoconferencing systems in LEO constellations. We observe that video quality
degrades due to inherent delays and network instability introduced by the high
altitude and rapid...

Random fluctuations caused by environmental noise can lead to decoherence in
quantum systems. Exploring and controlling such dissipative processes is both
fundamentally intriguing and essential for harnessing quantum systems to gain
practical advantages and deeper insights. In this work, we first demonstrate
the diffusive dynamics assisted by controlled dephasing noise in
superconducting quantum c...
Electron Wave-Spin Qubit
Ju Gao, Fang Shen • Published: 2025-04-26
As a continuation of our earlier investigations into electron
wave--spin~\citep{GaoJOPCO22,EntropyEvaSpin2024}, we analyze the electron spin
and its qubit in a cavity by treating the electron as a physical wave obeying
the Dirac equation. In this view, a qubit is a current--density configuration
whose orientation is fixed by the relative phase, rather than a particle
carrying simultaneous ``up'' a...
Vectorised Hashing Based on Bernstein-Rabin-Winograd Polynomials over Prime Order Fields
Kaushik Nath, Palash Sarkar • Published: 2025-07-09
We introduce the new AXU hash function decBRWHash, which is parameterised by
the positive integer $c$ and is based on Bernstein-Rabin-Winograd (BRW)
polynomials. Choosing $c>1$ gives a hash function which can be implemented
using $c$-way single instruction multiple data (SIMD) instructions. We report a
set of very comprehensive hand optimised assembly implementations of
4-decBRWHash using avx2 SIM...
A dataset and model for recognition of audiologically relevant environments for hearing aids: AHEAD-DS and YAMNet+
Henry Zhong, Jörg M. Buchholz, Julian Maclaren, Simon Carlile, Richard Lyon • Published: 2025-08-14
Scene recognition of audiologically relevant environments is important for
hearing aids; however, it is challenging, in part because of the limitations of
existing datasets. Datasets often lack public accessibility, completeness, or
audiologically relevant labels, hindering systematic comparison of machine
learning models. Deploying these models on resource-constrained edge devices
presents anothe...

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...
