Multiqubit Rydberg Gates for Quantum Error Correction
David F. Locher, Josias Old, Katharina Brechtelsbauer +4 more·Nov 30, 2025
Multiqubit gates that involve three or more qubits are usually thought to be of little significance for fault-tolerant quantum error correction because single gate faults can lead to high-weight correlated errors. However, recent works have shown tha...
Spectral form factor and power spectrum for trapped interacting rotating bosons: Crossover from integrability to quantum chaos
Mohd Talib, M. A. H. Ahsan·Nov 30, 2025
The emergence of quantum chaos in a system of trapped interacting bosons with externally impressed rotation is studied through spectral form factor (SFF) and power spectrum using exact diagonalization. Two distinct interaction regimes are considered:...
An approach to study the adiabaticity and irreversibility in the TDHO
Salvador J. Robles-Perez, Salvador Castillo-Rivera·Nov 30, 2025
This work studies the relationship between parametric amplification (or particle creation), adiabaticity and irreversibility in the non-quasi-static regime of a time-dependent quantum harmonic oscillator (TDHO) that evolves unitarily. We provide anal...
Braided QM and Majorana qubits at third root of unity: a color Heisenberg-Lie (super)algebra framework
Zhanna Kuznetsova, Francesco Toppan·Nov 30, 2025
We introduce color Heisenberg-Lie (super)algebras graded by the abelian groups $Z_3^2$, $Z_2^p\times Z_3^2$ for $p=1,2,3$, and investigate the properties of their associated multi-particle quantum paraoscillators. In the Rittenberg-Wyler's color Lie ...
Observation of individual vortex penetration in a coplanar superconducting resonator
Kirill Shulga, Shunsuke Nishimura, Pavel A. Volkov +7 more·Nov 30, 2025
We demonstrate the detection and control of individual Abrikosov vortices in superconducting microwave resonators. $λ/4$ resonators with a narrowed region near the grounded end acting as a vortex trap were fabricated and studied using microwave trans...
Super-Extensive Charging Power in the Absence of Global Operations
Anupam, Sheryl Mathew, Sibasish Ghosh·Nov 30, 2025
Quantum batteries have emerged as a platform for investigating whether quantum effects can accelerate energy storage beyond classical limits. Although a variety of charging schemes have reported signatures of quantum advantage, the fundamental physic...
Optimal Control of thermally noisy quantum gates in a multilevel system
Aviv Aroch, Shimshon Kallush, Ronnie Kosloff·Nov 30, 2025
Quantum systems are inherently sensitive to environmental noise and imperfections in external control fields, posing a significant challenge for the practical implementation of quantum technologies. These noise sources degrade the fidelity of quantum...
Boosting Gaussian Boson Sampling using Optical Parametric Amplification Networks
Yukuan Zhao, Xiao-Ye Xu, Chuan-Feng Li +1 more·Nov 30, 2025
Gaussian Boson Sampling (GBS) provides a route toward demonstrating quantum computational advantage. However, optical loss, which reduces the entanglement in the system, can render GBS results classically simulable. We propose a nonlinear photonic ar...
Fragmentation is Efficiently Learnable by Quantum Neural Networks
Mikhail Mints, Eric R. Anschuetz·Nov 30, 2025
Hilbert space fragmentation is a phenomenon in which the Hilbert space of a quantum system is dynamically decoupled into exponentially many Krylov subspaces. We can define the Schur transform as a unitary operation mapping some set of preferred bases...
Information conservation relations for weak measurement and its reversal
Yusef Maleki, Luis D. Zambrano Palma, M. Suhail Zubairy·Nov 30, 2025
We investigate the information distribution among different entities in the weak measurements protocol. Focusing on multilevel, decaying systems under continuous (no-click) monitoring, we derive exact, conservation-type information relations that hol...
Generalized Deutsch-Jozsa Algorithm for Applications in Data Classification, Logistic Regression, and Quantum Key Distribution
M. Ghadimi, V. Salari, S. Bakrani +4 more·Nov 30, 2025
We present a generalized Deutsch-Jozsa (DJ) quantum algorithm that not only determines both the global type of an unknown Boolean function (constant or balanced) but also determines explicit output values of the function in a single oracle query. Unl...
DyLoC: A Dual-Layer Architecture for Secure and Trainable Quantum Machine Learning Under Polynomial-DLA constraint
Chenyi Zhang, Tao Shang, Chao Guo +1 more·Nov 30, 2025
Variational quantum circuits face a critical trade-off between privacy and trainability. High expressivity required for robust privacy induces exponentially large dynamical Lie algebras. This structure inevitably leads to barren plateaus. Conversely,...
Weighted Projective Line ZX Calculus: Quantized Orbifold Geometry for Quantum Compilation
Gunhee Cho, Jason Cheng, Evelyn Li·Nov 30, 2025
We develop a unified geometric framework for quantum circuit compilation based on quantized orbifold phases and their diagrammatic semantics. Physical qubit platforms impose heterogeneous phase resolutions, anisotropic Bloch-ball contractions, and ha...
Curvature-Aware Optimization of Noisy Variational Quantum Circuits via Weighted Projective Line Geometry
Gunhee Cho, Jessie Wang, Angela Yue·Nov 30, 2025
We develop a differential-geometric framework for variational quantum circuits in which noisy single- and multi-qubit parameter spaces are modeled by weighted projective lines (WPLs). Starting from the pure-state Bloch sphere CP1, we show that realis...
Non-Negative Matrix Factorization Using Non-Von Neumann Computers
Ajinkya Borle, Charles Nicholas, Uchenna Chukwu +2 more·Nov 30, 2025
Non-negative matrix factorization (NMF) is a matrix decomposition problem with applications in unsupervised learning. The general form of this problem (along with many of its variants) is NP-hard in nature. In our work, we explore how this problem co...
On-Chip Levitated Neon Particle Arrays for Robust and Scalable Electron Qubits
Sosuke Inui, Yinghe Qi, Yiming Xing +3 more·Nov 29, 2025
Electron-on-neon (eNe) qubits have recently emerged as a compelling platform for quantum computing, which combines the vacuum isolation advantages of trapped-ion qubits with the scalability of superconducting circuits. In this system, electrons are t...

Woncheol Lee, Mark E. Turiansky, Dominic Waldhör +3 more·Nov 29, 2025
Bond breaking in the presence of highly energetic carriers is central to many important phenomena in physics and chemistry, including radiation damage, hot-carrier degradation, activation of dopant-hydrogen complexes in semiconductors, and photocatal...

Zain Ateeq, Muhammad Faryad·Nov 29, 2025
This work presents a differentiable geometric parameterization of quantum channels in Kraus representation, which can be efficiently probed to find an unknown quantum channel. We explore its feasibility in finding the quasi inverse channels, which ca...
Physical Probability in the Everett Interpretation and Bell Inequalities
Simon Saunders·Nov 29, 2025
I define a notion of local causality LOC closely modelled on the Bell principle, construed as the condition that single case probabilities cannot be modified by actions at spacelike separation. The new principle, like that of Bell, forces Bell inequa...
