−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 ...

processors communicating and cooperating to execute computational tasks is
considered as a promising solution to the scalability problem of reaching more
than thousands of ...
Observation of quantum-field-theory dynamics on a spin-phonon quantum computer
Anton T. Than, Saurabh V. Kadam, Vinay Vikramaditya, Nhung H. Nguyen, Xingxin Liu, Zohreh Davoudi, Alaina M. Green, Norbert M. Linke • Published: 2025-09-14
Simulating out-of-equilibrium dynamics of quantum field theories in nature is
challenging with classical methods, but is a promising application for quantum
computers. Unfortunately, simulating interacting bosonic fields involves a high
boson-to-qubit encoding overhead. Furthermore, when mapping to qubits, the
infinite-dimensional Hilbert space of bosons is necessarily truncated, with
truncation e...
Fault-Resilience of Dissipative Processes for Quantum Computing
James Purcell, Abhishek Rajput, Toby Cubitt • Published: 2025-02-27
Dissipative processes have long been proposed as a means of performing
computational tasks on quantum computers that may be intrinsically more robust
to noise. In this work, we prove two main results concerning the
error-resilience capabilities of two types of dissipative algorithms:
dissipative ground state preparation in the form of the dissipative quantum
eigensolver (DQE), and dissipative quan...

Michael A. Jones, Harish J. Vallury, Manolo C. Per, Harry M. Quiney, Lloyd C. L. Hollenberg • Published: 2025-09-13
With rapid progress being made in the development of platforms for quantum
computation, there has been considerable interest in whether present-day and
near-term devices can be used to solve problems of relevance. A commonly cited
application area is the domain of quantum chemistry. While most experimental
demonstrations of quantum chemical calculations on quantum devices have focused
on the groun...
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...

Quantum simulation offers a route to study open-system molecular dynamics in
non-perturbative regimes by programming the interactions among electronic,
vibrational, and environmental degrees of freedom on similar energy scales.
Trapped-ion systems possess this capability, with their native spins, phonons,
and tunable dissipation integrated within a single platform. Here, we
demonstrate an open-sys...
HiPARS: Highly-Parallel Atom Rearrangement Sequencer
Jonas Winklmann, Martin Schulz • Published: 2025-09-15
Neutral atom quantum computing's great scaling potential has resulted in it
emerging as a popular modality in recent years. For state preparation, atoms
are loaded stochastically and have to be detected and rearranged at runtime to
create a predetermined initial configuration for circuit execution. Such
rearrangement schemes either suffer from low parallelizability for
acousto-optic deflector (AOD...
Quantum metrology with a continuous-variable system
Matteo Fadel, Noah Roux, Manuel Gessner • Published: 2024-11-06
As one of the main pillars of quantum technologies, quantum metrology aims to
improve measurement precision using techniques from quantum information. The
two main strategies to achieve this are the preparation of nonclassical states
and the design of optimized measurement observables. We discuss precision
limits and optimal strategies in quantum metrology and sensing with a single
mode of quantum...
TEE is not a Healer: Rollback-Resistant Reliable Storage (Extended Version)
Sadegh Keshavarzi, Gregory Chockler, Alexey Gotsman • Published: 2025-05-24
Recent advances in secure hardware technologies, such as Intel SGX or ARM
TrustZone, offer an opportunity to substantially reduce the costs of Byzantine
fault-tolerance by placing the program code and state within a secure enclave
known as a Trusted Execution Environment (TEE). However, the protection offered
by a TEE only applies during program execution. Once power is switched off, the
non-volat...

Remote entanglement between independent and widely separated qubits is an
essential quantum phenomenon and a critical resource for quantum information
applications. Generating entanglement between qubits at arbitrary distances
requires the distribution of propagating quantum states. This necessity raises
the intriguing question whether the entanglement can be stabilized
indefinitely, instead of on...
