Scalable Asynchronous Single Flux Quantum Up-Down Counter Using Josephson Trapping Lines and $\alpha$-Cells
M. A. Karamuftuoglu, Beyza Zeynep Ucpinar, S. Razmkhah +1 more·May 7, 2025
We present a scalable, asynchronous up-down counter architecture implemented using single-flux quantum logic to enable efficient state management in superconductor digital systems. The proposed design eliminates the reliance on clocked storage elemen...
A Multi-Scale Quantum Framework for Evaluating Metal-Organic Frameworks in Carbon Capture
Tom W. A. Montgomery, Adrián Varela-Álvarez, Sam Genway +2 more·May 7, 2025
Metal Organic Frameworks (MOFs) are promising materials to help mitigate the effects of global warming by selectively absorbing $\text{CO}_{2}$ for direct capture. Accurate quantum chemistry simulations are a useful tool to help select and design opt...
Impact and mitigation of Hamiltonian characterization errors in digital-analog quantum computation
Mikel Garcia-de-Andoin, Alatz Álvarez-Ahedo, Adrián Franco-Rubio +1 more·May 6, 2025
Digital-analog is a universal quantum computing paradigm which employs the natural entangling Hamiltonian of the system and single-qubit gates as resources. Here, we study the stability of these protocols against Hamiltonian characterization errors. ...
Environmental Quantum States Trigger Emission in Nonlinear Photonics
Jia-Qi Li, Xin Wang·May 6, 2025
Light-matter interactions are traditionally governed by two fundamental paradigms: spontaneous and stimulated radiation. However, in nonlinear multi-photon regimes, these classical mechanisms break down, revealing new possibilities for light emission...
On the non-Markovian quantum stochastic network dynamics
Haijin Ding, Guofeng Zhang·May 6, 2025
In this paper, we investigate non-Markovian quantum dynamics from the perspective of quantum noises in a network of atoms mediated by a waveguide. In such networks, quantum coherent feedback control becomes achievable when coherent fields (or quantum...
Experimental Side-Channel-Secure Quantum Key Distribution over 200 km
Yang Zhou, Jing-Yang Liu, Chun-Hui Zhang +4 more·May 6, 2025
Quantum key distribution (QKD) enables two remote parties to share encryption keys with information-theoretic security guaranteed by physical laws. Side-channel-secure QKD (SCS-QKD) has attracted considerable attention because it simultaneously remov...
Quantum Feature Space of a Qubit Coupled to an Arbitrary Bath
Chris Wise, Akram Youssry, Alberto Peruzzo +2 more·May 6, 2025
Qubit control protocols have traditionally leveraged a characterisation of the qubit-bath coupling via its power spectral density. Previous work proposed the inference of noise operators that characterise the influence of a classical bath using a gre...
Qimax: Efficient quantum simulation via GPU-accelerated extended stabilizer formalism
Vu Tuan Hai, Bui Cao Doanh, Le Vu Trung Duong +2 more·May 6, 2025
Simulating Clifford and near-Clifford circuits using the extended stabilizer formalism has become increasingly popular, particularly in quantum error correction. Compared to the state-vector approach, the extended stabilizer formalism can solve the s...
Optical vortex generation by magnons with spin-orbit-coupled light
Ryusuke Hisatomi, Alto Osada, Kotaro Taga +5 more·May 6, 2025
Light possesses both spin and orbital angular momentum, which can spontaneously couple in spatially asymmetric optical fields. This phenomenon is referred to as optical spin-orbit coupling. This coupling is pivotal in modern optics due to its broad a...
Enhanced Simultaneous Quantum-Classical Communications Under Composable Security
Nicholas Zaunders, Ziqing Wang, Robert Malaney +2 more·May 6, 2025
Simultaneous quantum-classical communications (SQCC) protocols are a family of continuous-variable quantum key distribution (CV-QKD) protocols which allow for quantum and classical symbols to be integrated concurrently on the same optical pulse and m...
Sequential decoding of the XYZ$^2$ hexagonal stabilizer code
Basudha Srivastava, Yinzi Xiao, A. F. Kockum +2 more·May 6, 2025
Quantum error correction requires accurate and efficient decoding to optimally suppress errors in the encoded information. For concatenated codes, where one code is embedded within another, optimal decoding can be achieved using a message-passing alg...
Knowledge distillation inspired variational quantum eigensolver with virtual annealing
Junxu Li·May 6, 2025
In this paper, we propose a knowledge distillation inspired variational quantum eigensolver (KD-VQE). Inspired by the virtual distillation process in KD, KD-VQE introduces a virtual annealing mechanism to the VQE framework. In KD-VQE, measurement res...
Noisy HQNNs: A Comprehensive Analysis of Noise Robustness in Hybrid Quantum Neural Networks
Tasnim Ahmed, Alberto Marchisio, Muhammad Kashif +1 more·May 6, 2025
Hybrid Quantum Neural Networks (HQNNs) offer promising potential of quantum computing while retaining the flexibility of classical deep learning. However, the limitations of Noisy Intermediate-Scale Quantum (NISQ) devices introduce significant challe...
Digital quantum simulations of scattering in quantum field theories using W states
R. Farrell, Nikita A. Zemlevskiy, Marc Illa +1 more·May 6, 2025
High-energy particle collisions can convert energy into matter through the inelastic production of new particles. Quantum computers are an ideal platform for simulating the out-of-equilibrium dynamics of collisions and the formation of subsequent man...

We present a quantum computational framework using Hamiltonian Truncation (HT) for simulating real-time scattering processes in $(1+1)$-dimensional scalar $\phi^4$ theory. Unlike traditional lattice discretisation methods, HT approximates the quantum...
Comparing classical and quantum conditional disclosure of secrets
Uma Girish, Alex May, Leo Orshansky +1 more·May 5, 2025
The conditional disclosure of secrets (CDS) setting is among the most basic primitives studied in information-theoretic cryptography. Motivated by a connection to non-local quantum computation and position-based cryptography, CDS with quantum resourc...

I. Arrazola, P. Bertet, Y. Chu +1 more·May 5, 2025
We study a generic cavity QED setup under conditions where the coupling between the two-level systems and a single bosonic mode is significantly degraded by low-frequency noise. To overcome this problem, we identify pulsed dynamical decoupling strate...
Stabilizer-Accelerated Quantum Many-Body Ground-State Estimation
Caroline E. P. Robin·May 5, 2025
We investigate how the stabilizer formalism, in particular highly-entangled stabilizer states, can be used to describe the emergence of many-body shape collectivity from individual constituents, in a symmetry-preserving and classically efficient way....

Jai Prakash Veerla, Partha Sai Guttikonda, Helen H. Shang +3 more·May 5, 2025
Pathologists diagnose cancer using gigapixel whole-slide images (WSIs), but the current digital workflow is fragmented. These multiscale datasets often exceed 100,000 x 100,000 pixels, yet standard 2D monitors restrict the field of view. This dispari...
