The Fermi-Hubbard model is a fundamental model in condensed matter physics
that describes strongly correlated electrons. On the other hand, quantum
computers are emerging as powerful tools for exploring the complex dynamics of
these quantum many-body systems. In this work, we demonstrate the quantum
simulation of the one-dimensional Fermi-Hubbard model using IBM's
superconducting quantum computers...
Mitigating the sign problem by quantum computing
Kwai-Kong Ng, Min-Fong Yang • Published: 2025-09-16
The notorious sign problem severely limits the applicability of quantum Monte
Carlo (QMC) simulations, as statistical errors grow exponentially with system
size and inverse temperature. A recent proposal of a quantum-computing
stochastic series expansion (qc-SSE) method suggested that the problem could be
avoided by introducing constant energy shifts into the Hamiltonian. Here we
critically examin...

Maria-Catalina Isfan, Laurentiu-Ioan Caramete, Ana Caramete, Daniel Tonoiu, Alexandru Nicolin-Zaczek • Published: 2025-09-16
The field of gravitational wave (GW) detection is progressing rapidly, with
several next-generation observatories on the horizon, including LISA. GW data
is challenging to analyze due to highly variable signals shaped by source
properties and the presence of complex noise. These factors emphasize the need
for robust, advanced analysis tools. In this context, we have initiated the
development of a ...
Extension of the Jordan-Wigner mapping to nonorthogonal spin orbitals for quantum computing application to valence bond approaches
Alessia Marruzzo, Mosè Casalegno, Piero Macchi, Fabio Mascherpa, Bernardino Tirri, Guido Raos, Alessandro Genoni • Published: 2025-09-16
Quantum computing offers a promising platform to address the computational
challenges inherent in quantum chemistry, and particularly in valence bond (VB)
methods, which are chemically appealing but suffer from high computational cost
due to the use of nonorthogonal orbitals. While various fermionic-to-spin
mappings exist for orthonormal spin orbitals, such as the widely used
Jordan-Wigner transfo...
Measurement-free code-switching for low overhead quantum computation using permutation invariant codes
Yingkai Ouyang, Yumang Jing, Gavin K. Brennen • Published: 2024-11-20
Transversal gates on quantum error correction codes have been a promising
approach for fault-tolerant quantum computing, but are limited by the
Eastin-Knill no-go theorem. Existing solutions like gate teleportation and
magic state distillation are resource-intensive. We present a measurement-free
code-switching protocol for universal quantum computation, switching between a
stabiliser code for tra...
Evaluating Variational Quantum Circuit Architectures for Distributed Quantum Computing
Leo Sünkel, Jonas Stein, Jonas Nüßlein, Tobias Rohe, Claudia Linnhoff-Popien • Published: 2025-09-15
Scaling quantum computers, i.e., quantum processing units (QPUs) to enable
the execution of large quantum circuits is a major challenge, especially for
applications that should provide a quantum advantage over classical algorithms.
One approach to scale QPUs is to connect multiple machines through quantum and
classical channels to form clusters or even quantum networks. Using this
paradigm, severa...
New Lower-bounds for Quantum Computation with Non-Collapsing Measurements
David Miloschewsky, Supartha Podder • Published: 2024-11-06
Aaronson, Bouland, Fitzsimons and Lee introduced the complexity class PDQP
(which was original labeled naCQP), an alteration of BQP enhanced with the
ability to obtain non-collapsing measurements, samples of quantum states
without collapsing them. Although PDQP contains SZK, it still requires
$\Omega(N^{1/4})$ queries to solve unstructured search. We formulate an
alternative equivalent definition ...
Quantum Computation with Correlated Measurements: Implications for the Complexity Landscape
David Miloschewsky, Supartha Podder • Published: 2025-07-04
In 2004, Aaronson introduced the complexity class $\mathsf{PostBQP}$
($\mathsf{BQP}$ with postselection) and showed that it is equal to
$\mathsf{PP}$. In this paper, we define a new complexity class,
$\mathsf{CorrBQP}$, a modification of $\mathsf{BQP}$ which has the power to
perform correlated measurements, i.e. measurements that output the same value
across a partition of registers. We show that ...

Precision atomic and quantum experiments rely on ultra-stable narrow
linewidth lasers constructed using table-top ultra-low expansion reference
cavities. These experiments often require multiple lasers, operating at
different wavelengths, to perform key steps used in state preparation and
measurement required in quantum sensing and computing. This is traditionally
achieved by disciplining a cavity...

Fernando L. Semião, Matthias Keller • Published: 2025-01-06
Using a shared microwave resonator, we propose a transduction scheme between
superconducting qubits and qubit states encoded in the low-lying internal
levels of trapped atomic systems. The approach employs atomic Rydberg levels
together with laser pulses that connect them to the low-lying qubit states. We
explore two coupling protocols: one based on resonant interactions between the
subsystems, an...

Py maidr: Bridging Visual and Non-Visual Data Experiences Through a Unified Python Framework
JooYoung Seo, Saairam Venkatesh, Daksh Pokar, Sanchita Kamath, Krishna Anandan Ganesan • Published: 2025-09-16
Although recent efforts have developed accessible data visualization tools
for blind and low-vision (BLV) users, most follow a "design for them" approach
that creates an unintentional divide between sighted creators and BLV
consumers. This unidirectional paradigm perpetuates a power dynamic where
sighted creators produce non-visual content boundaries for BLV consumers to
access. This paper propose...

The emergent practical applicability of the Quantum Approximate Optimization
Algorithm (QAOA) for approximate combinatorial optimization is a subject of
considerable interest. One of the primary limitations of QAOA is the task of
finding a set of good parameters. Parameter transfer is a phenomenon where QAOA
angles trained on problem instances that are self-similar tend to perform well
for other p...
