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

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...
Towards reconstructing quantum structured light on a quantum computer
Mwezi Koni, Shawal Kasim, Paola C. Obando, Neelan Gounden, Isaac Nape • Published: 2025-09-26
We introduce a variational quantum computing approach for reconstructing
quantum states from measurement data. By mapping the reconstruction cost
function onto an Ising model, the problem can be solved using a variational
eigensolver on present-day quantum hardware. As a proof of concept, we
demonstrate the method on quantum structured light, in particular, entangled
photons carrying orbital angul...

Vincent Mutolo, Devon Campbell, Quinn Manning, Henri Witold Dubourg, Ruibin Lyu, Simha Sethumadhavan, Daniel Rubenstein, Salvatore Stolfo • Published: 2025-06-19
As quantum computing matures and moves toward broader accessibility through
cloud-based platforms, ensuring the authenticity and integrity of quantum
computations becomes an urgent concern. In this work, we propose a strategy to
leverage the byproducts of quantum error correction (QEC) to verify hardware
identity and authenticate quantum computations for "free", without introducing
any additional ...
Scalable modular architecture for universal quantum computation
Fernando Gago-Encinas, Christiane P. Koch • Published: 2025-07-19
Universal quantum computing requires the ability to perform every unitary
operation, i.e., evolution operator controllability. In view of developing
resource-efficient quantum processing units (QPUs), it is important to
determine how many local controls and qubit-qubit couplings are required for
controllability. Unfortunately, assessing the controllability of large qubit
arrays is a difficult task...

Arturo Acuaviva, David Aguirre, Rubén Peña, Mikel Sanz • Published: 2024-07-15
The technological development of increasingly larger quantum processors on
different quantum platforms raises the problem of how to fairly compare their
performance, known as quantum benchmarking of quantum processors. This is a
challenge that computer scientists have already faced when comparing classical
processors, leading to the development of various mathematical tools to address
it, but also...

SkyLink: Unifying Street-Satellite Geo-Localization via UAV-Mediated 3D Scene Alignment
Hongyang Zhang, Yinhao Liu, Zhenyu Kuang • Published: 2025-09-29
Cross-view geo-localization aims at establishing location correspondences
between different viewpoints. Existing approaches typically learn cross-view
correlations through direct feature similarity matching, often overlooking
semantic degradation caused by extreme viewpoint disparities. To address this
unique problem, we focus on robust feature retrieval under viewpoint variation
and propose the n...

Quantum error detection is essential in realizing large-scale universal
quantum computation, especially for quantum error correction (QEC). However,
key elements for FTQC have yet to be realized in silicon qubits. Here, we
demonstrate quantum error detection on a donor-based silicon quantum processor
comprising four-nuclear spin qubits and one electron spin as an auxiliary
qubit. The entanglement ...

Christian W. Binder, Guido Burkard, Andrew J. Fisher • Published: 2025-07-31
We present a rigorous method to reduce the three-dimensional (3D) description
of a quantum dot in silicon to an effective two-dimensional (2D) envelope
function theory for electron spin qubits. By systematically integrating out the
strongly confined vertical dimension using a Born-Oppenheimer-inspired ansatz
at the envelope-function level, we derive an effective in-plane potential that
faithfully ...
Broadband Magnetless Isolator using Adiabatic Flux Modulation
M. Demarets, A. M. Vadiraj, C. Caloz, K. De Greve • Published: 2025-09-29
Isolators are commonly found in the amplification chain of microwave setups
to shield sensitive devices such as superconducting qubits from noise and
back-scattered signals. Conventional ferrite-based isolators are bulky, lossy
and rely on strong magnetic fields, which pose challenges for their
co-integration in large-scale superconducting devices. Here, we present a
magnetless isolator that overc...
