−TASI/CERN/KITP Lecture Notes on "Toward Quantum Computing Gauge Theories of Nature"
Zohreh Davoudi • Published: 2025-07-21
A hallmark of the computational campaign in nuclear and particle physics is
the lattice-gauge-theory program. It continues to enable theoretical
predictions for a range of phenomena in nature from the underlying Standard
Model. The emergence of a new computational paradigm based on quantum
computing, therefore, can introduce further advances in this program. In
particular, it is believed that quan...
Enhanced fill probability estimates in institutional algorithmic bond trading using statistical learning algorithms with quantum computers
Axel Ciceri, Austin Cottrell, Joshua Freeland, Daniel Fry, Hirotoshi Hirai, Philip Intallura, Hwajung Kang, Chee-Kong Lee, Abhijit Mitra, Kentaro Ohno, Das Pemmaraju, Manuel Proissl, Brian Quanz, Del Rajan, Noriaki Shimada, Kavitha Yograj • Published: 2025-09-22
The estimation of fill probabilities for trade orders represents a key
ingredient in the optimization of algorithmic trading strategies. It is bound
by the complex dynamics of financial markets with inherent uncertainties, and
the limitations of models aiming to learn from multivariate financial time
series that often exhibit stochastic properties with hidden temporal patterns.
In this paper, we f...
Parton Distributions on a Quantum Computer
Jiunn-Wei Chen, Yu-Ting Chen, Ghanashyam Meher • Published: 2025-06-20
We perform the first quantum computation of parton distribution function
(PDF) with a real quantum device by calculating the PDF of the lightest
positronium in the Schwinger model with IBM quantum computers. The calculation
uses 10 qubits for staggered fermions at five spatial sites and one ancillary
qubit. The most critical and challenging step is to reduce the number of
two-qubit gate depths to ...
A Provably Secure Framework for Noise-Aware Delegated Quantum Computation and Storage
Sanidhya Gupta, Ankur Raina • Published: 2024-03-12
As large-scale quantum computers become a reality, they will likely exist as
centralized cloud resources accessible to a broad user base. Securely
delegating private quantum computations to untrusted servers is therefore a
foundational challenge. This requires rigorous, provable guarantees of privacy
(blindness), cor- rectness (completeness), and integrity against malicious
actions (verifiability)...
Quantum-Computer-Based Verification of Quantum Thermodynamic Uncertainty Relation
Nobumasa Ishida, Yoshihiko Hasegawa • Published: 2024-02-29
Quantum thermodynamic uncertainty relations establish fundamental trade-offs
between the precision achievable in quantum systems and associated
thermodynamic quantities such as entropy production or dynamical activity.
While foundational, empirical demonstrations have thus far been confined to
specific cases, either assuming time-reversal symmetry or involving particular
measurement types, leaving...
Task-Oriented Gaussian Optimization for Non-Gaussian Resources in Continuous-Variable Quantum Computation
Boxuan Jing, Feng-Xiao Sun, Qiongyi He • Published: 2025-09-19
In continuous-variable systems, non-Gaussian resources are essential for
achieving universal quantum computation that lies beyond classical simulation.
Among the candidate states, the cubic phase state stands out as the simplest
form of single-mode non-Gaussian resource, yet its experimental preparation
still remains a great challenge. Although a variety of approximate schemes have
been proposed t...
Discrete Flow-Based Generative Models for Measurement Optimization in Quantum Computing
Isaac L. Huidobro-Meezs, Jun Dai, Rodrigo A. Vargas-Hernández • Published: 2025-09-18
Achieving chemical accuracy in quantum simulations is often constrained by
the measurement bottleneck: estimating operators requires a large number of
shots, which remains costly even on fault-tolerant devices and is further
exacerbated on today's noisy hardware by finite circuit fidelity and
error-mitigation overhead. Addressing this challenge involves a multiobjective
optimization problem that b...
Fault-tolerant quantum computing with a high-rate symplectic double code
Naoyuki Kanomata, Hayato Goto • Published: 2025-09-18
High-rate and large-distance quantum codes are expected to make
fault-tolerant quantum computing more efficient, but most of them lack
efficient fault-tolerant encoded-state preparation methods. We propose such a
fault-tolerant encoder for a [[30, 6, 5]] symplectic double code. The advantage
of this code is its compactness, in addition to its high encoding rate,
allowing for early experimental rea...
Capturing the Page Curve and Entanglement Dynamics of Black Holes in Quantum Computers
Talal Ahmed Chowdhury, Kwangmin Yu, Muhammad Asaduzzaman, Raza Sabbir Sufian • Published: 2024-12-19
Quantum computers are emerging technologies expected to become important
tools for exploring various aspects of fundamental physics in the future.
Therefore, we pose the question of whether quantum computers can help us to
study the Page curve and the black hole information dynamics, which has been a
key focus in fundamental physics. In this regard, we rigorously examine the
qubit transport model,...

Niklas Mueller, Tianyi Wang, Or Katz, Zohreh Davoudi, Marko Cetina • Published: 2024-07-31
Simulating non-equilibrium phenomena in strongly-interacting quantum
many-body systems, including thermalization, is a promising application of
near-term and future quantum computation. By performing experiments on a
digital quantum computer consisting of fully-connected optically-controlled
trapped ions, we study the role of entanglement in the thermalization dynamics
of a $Z_2$ lattice gauge the...

−Magnetic-Field and Temperature Limits of a Kinetic-Inductance Traveling-Wave Parametric Amplifier
Lucas M. Janssen, Farzad Faramarzi, Henry G. LeDuc, Sahil Patel, Gianluigi Catelani, Peter K. Day, Yoichi Ando, Christian Dickel • Published: 2025-09-18
Kinetic-inductance traveling-wave parametric amplifiers (KI-TWPAs) offer
broadband near-quantum-limited amplification with high saturation power. Due to
the high critical magnetic fields of high-kinetic-inductance materials,
KI-TWPAs should be resilient to magnetic fields. In this work, we study how
magnetic field and temperature affect the performance of a KI-TWPA based on a
thin-NbTiN inverse mi...

Roberto Stassi, Shilan Abo, Daniele Lamberto, Ye-Hong Chen, Adam Miranowicz, Salvatore Savasta, Franco Nori • Published: 2025-09-22
To achieve a fault-tolerant quantum computer, it is crucial to increase the
coherence time of quantum bits. In this work, we theoretically investigate a
system consisting of a series of superconducting qubits that alternate between
XX and YY ultrastrong interactions. By considering the two-lowest energy
eigenstates of this system as a {\it logical} qubit, we demonstrate that its
coherence is signi...

V. M. Schäfer, A. C. Hughes, O. Bazavan, K. Thirumalai, G. Pagano, C. J. Ballance, D. M. Lucas • Published: 2025-09-22
Entangling gates are an essential capability of quantum computers. There are
different methods for implementing two-qubit gates, with respective advantages
and disadvantages. We investigate the experimentally relevant differences and
commonalities of laser-based $\sigma_z\otimes\sigma_z$ light-shift and
$\sigma_\phi\otimes\sigma_\phi$ Moelmer-Soerensen gates, highlighting the
phases of experimenta...

and clouds which connect with the even longer (0.5 Mpc) tail of gas previously
discovered...
Conditional Diffusion Models for CT Image Synthesis from CBCT: A Systematic Review
Alzahra Altalib, Chunhui Li, Alessandro Perelli • Published: 2025-09-22
Objective: Cone-beam computed tomography (CBCT) provides a low-dose imaging
alternative to conventional CT, but suffers from noise, scatter, and artifacts
that degrade image quality. Synthetic CT (sCT) aims to translate CBCT to
high-quality CT-like images for improved anatomical accuracy and dosimetric
precision. Although deep learning approaches have shown promise, they often
face limitations in ...
Hybrid Trapping of Cold Atoms with Surface Forces and Blue-Detuned Evanescent Light on a Nanophotonic Waveguide
Riccardo Pennetta, Antoine Glicenstein, Philipp Schneeweiss, Jürgen Volz, Arno Rauschenbeutel • Published: 2025-09-22
We demonstrate a novel hybrid nanophotonic trap for cold neutral atoms,
leveraging surface forces for attraction and blue-detuned evanescent light for
repulsion. We attribute the attractive potential to a combination of
Casimir-Polder interactions and electrostatic charges distributed on the
waveguide surface. Despite the trap's shallow depth, we efficiently load atoms
into it via adiabatic transf...

Avinash Pathapati, Olli Mansikkamäki, Alexander Tyner, Alexander V. Balatsky • Published: 2025-09-22
We introduce a data-driven approach for extracting two-level system (TLS)
parameters-frequency $\omega_{TLS}$, coupling strength $g$, dissipation time
$T_{TLS, 1}$, and the pure dephasing time $T^{\phi}_{TLS, 2}$, labelled as a
4-component vector $\vec{q}$, directly from simulated spectroscopy data
generated for a single TLS by a form of two-tone spectroscopy. Specifically, we
demonstrate that a c...
