−Enhancing Optical Imaging via Quantum Computation
Aleksandr Mokeev, Babak Saif, Mikhail D. Lukin, Johannes Borregaard • Published: 2025-09-11
Extracting information from weak optical signals is a critical challenge
across a broad range of technologies. Conventional imaging techniques,
constrained to integrating over detected signals and classical post-processing,
are limited in signal-to-noise ratio (SNR) from shot noise accumulation in the
post-processing algorithms. We show that these limitations can be circumvented
by coherently enco...

Daan Camps, Ermal Rrapaj, Katherine Klymko, Hyeongjin Kim, Kevin Gott, Siva Darbha, Jan Balewski, Brian Austin, Nicholas J. Wright • Published: 2025-09-11
The National Energy Research Scientific Computing Center (NERSC), as the
high-performance computing (HPC) facility for the Department of Energy's Office
of Science, recognizes the essential role of quantum computing in its future
mission. In this report, we analyze the NERSC workload and identify materials
science, quantum chemistry, and high-energy physics as the science domains and

Special Issue: Commemorating the 110th Anniversary of TANG Au-chin's Birthday Calculation of the Green's function on near-term quantum computers via Cartan decomposition
Lingyun Wan, Jie Liu, Jinlong Yang • Published: 2025-09-11
Accurate computation of the Green's function is crucial for connecting
experimental observations to the underlying quantum states. A major challenge
in evaluating the Green's function in the time domain lies in the efficient
simulation of quantum state evolution under a given Hamiltonian-a task that
becomes exponentially complex for strongly correlated systems on classical
computers. Quantum compu...
QubitHammer: Remotely Inducing Qubit State Change on Superconducting Quantum Computers
Yizhuo Tan, Navnil Choudhury, Kanad Basu, Jakub Szefer • Published: 2025-04-10
To address the rapidly growing demand for cloud-based quantum computing,
various researchers are proposing shifting from the existing single-tenant
model to a multi-tenant model that expands resource utilization and improves
accessibility. However, while multi-tenancy enables multiple users to access
the same quantum computer, it introduces potential for security and reliability
vulnerabilities. I...
Adaptive Quantum Computers: decoding and state preparation
Niels M. P. Neumann • Published: 2025-09-10
Interacting with a standard computer can enhance the capabilities of current
quantum computers already today, particularly by offloading certain
computations to the standard computer. Quantum computers that interact with
standard computers to perform computations are called adaptive quantum
computers. This work formalizes a model that describes these adaptive quantum
computers. As quantum computer...
Atomic diffraction by patterned holes in hexagonal boron nitride: a comparison between semi-classical and quantum computational models
Eivind Kristen Osestad, Ekaterina Zossimova, Michael Walter, Johannes Fiedler • Published: 2025-09-10
The diffraction of atoms and molecules through tiny, sub-nanometre holes in
atomically thin membranes is a promising approach for advancing atom
interferometry sensing and atomic holography. However, dispersion interactions,
such as the Casimir-Polder force, pose a significant challenge by attracting
diffracting particles to the membrane, limiting the minimum hole size. This
paper presents a numer...

Talha Azfar, Osama Muhammad Raisuddin, Ruimin Ke, Jose Holguin-Veras • Published: 2025-05-02
The Vehicle Routing Problem (VRP) is a fundamental combinatorial optimization
challenge with broad applications in logistics and transportation. In this
work, we present a quantum-assisted framework that integrates the Quantum
Approximate Optimization Algorithm (QAOA) with a link-based formulation of VRP.
Our approach encodes flow conservation and subtour elimination directly into
the cost Hamilto...
Evolutionary-Based Circuit Optimization for Distributed Quantum Computing
Leo Sünkel, Jonas Stein, Gerhard Stenzel, Michael Kölle, Thomas Gabor, Claudia Linnhoff-Popien • Published: 2025-09-09
In this work, we evaluate an evolutionary algorithm (EA) to optimize a given
circuit in such a way that it reduces the required communication when executed
in the Distributed Quantum Computing (DQC) paradigm. We evaluate our approach
for a state preparation task using Grover circuits and show that it is able to
reduce the required global gates by more than 89% while still achieving high
fidelity a...
Fusion for High-Dimensional Linear Optical Quantum Computing with Improved Success Probability
Gözde Üstün, Eleanor G. Rieffel, Simon J. Devitt, Jason Saied • Published: 2025-05-22
Type-II fusion is a probabilistic entangling measurement that is essential to
measurement-based linear optical quantum computing and can be used for quantum
teleportation more broadly. However, it remains under-explored for
high-dimensional qudits. Our main result gives a Type-II fusion protocol with
proven success probability approximately $2/d^2$ for qudits of arbitrary
dimension $d$. This gener...

Kazuki Sakamoto, Keisuke Fujii • Published: 2025-05-15
The simulation of large-scale classical systems in exponentially small space
on quantum computers has gained attention. The prior work demonstrated that a
quantum algorithm offers an exponential speedup over any classical algorithm in
simulating classical dynamics with long-range interactions. However, many
real-world classical systems, such as those arising from partial differential
equations, ex...

Matee ur Rehman, Paul Winter, Fabio Revuelta, Alejandro Saenz • Published: 2025-09-12
Recent advancements in optical tweezers enable the trapping of arbitrary
numbers of neutral atoms and molecules, even arrays of tweezers with variable
geometry can be realized. These fascinating breakthroughs require novel
full-dimensional beyond mean-field treatments for systems with more than two
confined particles spread over traps that are arranged arbitrarily in space. In
this work, the suita...
Spin-qubit Noise Spectroscopy of Magnetic Berezinskii-Kosterlitz-Thouless Physics
Mark Potts, Shu Zhang • Published: 2025-09-12
We propose using spin-qubit noise magnetometry to probe dynamical signatures
of magnetic Berezinskii-Kosterlitz-Thouless (BKT) physics. For a
nitrogen-vacancy (NV) center coupled to two-dimensional XY magnets, we predict
distinctive features in the magnetic noise spectral density in the sub-MHz to
GHz frequency range. In the quasi-long-range ordered phase, the spectrum
exhibits a temperature-depen...
Quantum Dissipative Continuous Time Crystals
Felix Russo, Thomas Pohl • Published: 2025-03-20
Continuous time crystals, i.e., nonequilibrium phases with a spontaneously
broken continuous time-translational symmetry, have been studied and recently
observed in the long-time dynamics of open quantum systems. Here, we
investigate a lattice of interacting three-level particles and find two
distinct time-crystal phases that cannot be described within mean-field theory.
Remarkably, one of them em...
SU(3) rigid triaxiality in $^{154}$Sm
Chunxiao Zhou, Xue Shang, Tao Wang • Published: 2025-09-12
The $^{154}$Sm nucleus, which has long been regarded as a typical quantum
system exhibiting axial symmetry, has been recently suggested to exhibit a
small degree of triaxiality by Otsuka \textit{et al.}. This small triaxiality
was recently observed using the $\gamma$ decay of the $^{154}$Sm isovector
giant dipole resonance. Thus further studying this small triaxiality is very
necessary for underst...

Milind Upadhyay, Mark Nicholas Jones • Published: 2025-09-11
For various optimization problems, the classical time to solution is
super-polynomial and intractable to solve with classical bit-based computing
hardware to date. Digital and quantum annealers have the potential to identify
near-optimal solutions for such optimization problems using a quadratic
unconstrained binary optimization (QUBO) problem formulation. This work
benchmarks two use cases to eva...

Predicting a mobile app's popularity before its first release can provide
developers with a strategic advantage in a competitive marketplace, yet it
remains a challenging problem. This study explores the extent to which internal
software metrics, measurable from source code before deployment, can predict an
app's popularity (i.e., ratings and downloads per year) at inception. For our
analysis, we ...
