Leveraging Machine Learning Force Fields (MLFFs) to Simulate Large Atomistic Systems for Fidelity Improvement of Superconducting Qubits and Sensors
Søren Smidstrup, Shela Aboud, Ricardo Borges +4 more·Sep 15, 2025
Materials engineering using atomistic modeling is an essential tool for the development of qubits and quantum sensors. Traditional density-functional theory (DFT) does however not adequately capture the complete physics involved, including key aspect...
Enlarging the GKP stabilizer group for enhanced noise protection
Jonathan Pelletier, Baptiste Royer·Sep 15, 2025
Encoding a qubit in a larger Hilbert space of an oscillator is an efficient way to protect its quantum information against decoherence. Promising examples of such bosonic encodings are the Gottesman-Kitaev-Preskill (GKP) codes. In this work, we inves...
Integrated Software/Hardware Execution Models for High-Accuracy Methods in Chemistry
Nicholas Bauman, Ajay Panyala, Libor Veis +7 more·Sep 15, 2025
The effective deployment and application of advanced methodologies for quantum chemistry is inherently linked to the optimal usage of emerging and highly diversified computational resources. This paper examines the synergistic utilization of Micron m...
QKD Oracles for Authenticated Key Exchange
Kathrin Hövelmanns, Daan Planken, Christian Schaffner +1 more·Sep 15, 2025
Authenticated Key Exchange (AKE) establishes shared ('symmetric') cryptographic keys which are essential for secure online communication. AKE protocols can be constructed from public-key cryptography like Key Encapsulation Mechanisms (KEMs). Another ...
Efficient Privacy-Preserving Training of Quantum Neural Networks by Using Mixed States to Represent Input Data Ensembles
Gaoyuan Wang, Jonathan Warrell, Mark Gerstein·Sep 15, 2025
Quantum neural networks (QNNs) are gaining increasing interest due to their potential to detect complex patterns in data by leveraging uniquely quantum phenomena. This makes them particularly promising for biomedical applications. In these applicatio...
Neural-Quantum-States Impurity Solver for Quantum Embedding Problems
Yinzhanghao Zhou, Tsung-Han Lee, Ao Chen +2 more·Sep 15, 2025
Neural quantum states (NQS) have emerged as a promising approach to solve second-quantized Hamiltonians, because of their scalability and flexibility. In this work, we design and benchmark an NQS impurity solver for the quantum embedding (QE) methods...
Efficient Entanglement Purification Circuit Design for Dual-Species Atom Arrays
Bikun Li, Daniel Dilley, Alvin Gonzales +6 more·Sep 15, 2025
Entanglement purification protocols (EPPs) are essential for generating high-fidelity entangled states in noisy quantum systems, enabling robust quantum networking and computation. Building on the circuit of the foundational recurrence protocol, we g...
Numerical Optimization Methods in the environment with Quantum Noise
Tomáš Bezděk·Sep 15, 2025
The accurate calculation of electronic potential energy surfaces for ground and excited states is crucial for understanding photochemical processes, particularly near conical intersections. While classical methods are limited by scaling and quantum a...
Entanglement and optimization within autoregressive neural quantum states
Andrew Jreissaty, Hang Zhang, Jairo C. Quijano +2 more·Sep 15, 2025
Neural quantum states (NQSs) are powerful variational ansätze capable of representing highly entangled quantum many-body wavefunctions. While the average entanglement properties of ensembles of restricted Boltzmann machines are well understood, the e...
A graphical diagnostic of topological order using ZX calculus
Sergi Mas-Mendoza, Richard D. P. East, Michele Filippone +1 more·Sep 15, 2025
Establishing a universal diagnostic of topological order remains an open theoretical challenge. In particular, diagnosing long-range entanglement through the entropic area law suffers from spurious contributions, failing to unambiguously identify top...
Exact Coset Sampling for Quantum Lattice Algorithms
Yifan Zhang·Sep 15, 2025
We revisit the post-processing phase of Chen's Karst-wave quantum lattice algorithm (Chen, 2024) in the Learning with Errors (LWE) parameter regime. Conditioned on a transcript $E$, the post-Step 7 coordinate state on $(\mathbb{Z}_M)^n$ is supported ...
Privacy in continuous-variable distributed quantum sensing
A. de Oliveira Junior, Anton L. Andersen, Benjamin Lundgren Larsen +5 more·Sep 15, 2025
Can a distributed network of quantum sensors estimate a global parameter while protecting every locally encoded value? We answer this question affirmatively by introducing and analysing a protocol for distributed quantum sensing in the continuous-var...
Accurate ground states of $SU(2)$ lattice gauge theory in 2+1D and 3+1D
Thomas Spriggs, Eliska Greplova, Juan Carrasquilla +1 more·Sep 15, 2025
We present a neural network wavefunction framework for solving non-Abelian lattice gauge theories in a continuous group representation. Using a combination of $SU(2)$ equivariant neural networks alongside an $SU(2)$ invariant, physics-inspired ansatz...
Driven-Dissipative Landau Polaritons: Two Highly Nonlinearly-Coupled Quantum Harmonic Oscillators
Farokh Mivehvar·Sep 15, 2025
Landau levels (LLs) are the massively-degenerate discrete energy spectrum of a charged particle in a transverse magnetic field and lie at the heart of many intriguing phenomena such as the integer and fractional quantum Hall effects as well as quanti...
On the fate of spacetime singularities
Federico Piazza·Sep 15, 2025
I investigate spacetime singularities from the point of view of the wavefunction of the universe. In order to extend the classical notion of geodesic incompleteness one has to include the proper time of an observer as a degree of freedom in the Wheel...
Higher-Form Anomalies on Lattices
Yitao Feng, Ryohei Kobayashi, Yu-An Chen +1 more·Sep 15, 2025
Higher-form symmetry in a tensor product Hilbert space is always emergent: the symmetry generators become genuinely topological only when the Gauss law is energetically enforced at low energies. In this paper, we present a general method for defining...
Phases of 2d Gauge Theories and Symmetric Mass Generation
Rishi Mouland, David Tong, Bernardo Zan·Sep 15, 2025
We study the dynamics and phase structure of Abelian gauge theories in $d=1+1$ dimensions. These include $U(1)$ gauge theory coupled to a scalar and a fermion, as well as the two-flavour Schwinger model with different charges. Both theories exhibit a...

Brendan P. Marsh, David Atri Schuller, Yunpeng Ji +5 more·Sep 15, 2025
The Hopfield model describes a neural network that stores memories using all-to-all-coupled spins. Memory patterns are recalled under equilibrium dynamics. Storing too many patterns breaks the associative recall process because frustration causes an ...
