Statistics-governed dynamical scaling in interacting anyonic chains
Xu-Chen Yang, Botao Wang, Jianpeng Liu +3 more·Mar 16, 2026
Particle statistics impose fundamental constraints on nonequilibrium quantum dynamics, yet it remains an open question whether anyonic statistics can lead to emergent dynamical scaling beyond the conventional Bose-Fermi paradigm. Here we investigate ...
Post-selected Criticality in Measurement-induced Phase Transitions
Dolly Nambi, Kabir Khanna, Andrew Allocca +4 more·Mar 16, 2026
Information-theoretic phase transitions, such as the measurement-induced phase transition (MIPT), characterize the robustness of quantum dynamics to local monitoring and are naturally formulated in terms of trajectories conditioned on typical measure...
A direct controlled-phase gate between microwave photons
Adrian Copetudo, Amon M. Kasper, Tanjung Krisnanda +4 more·Mar 16, 2026
The rich dynamics and large Hilbert space of quantum harmonic oscillators make them natural candidates for hardware-efficient and error-correctable quantum information processing. However, implementing direct entangling operations between oscillators...
Quantum-Inspired Unitary Pooling for Multispectral Satellite Image Classification
Georgios Maragkopoulos, Aikaterini Mandilara, Ralntion Komini +1 more·Mar 16, 2026
Multispectral satellite imagery poses significant challenges for deep learning models due to the high dimensionality of spectral data and the presence of structured correlations across channels. Recent work in quantum machine learning suggests that u...
Ab Initio Study of Erbium Point Defects in 4H-SiC for Quantum Devices
Michael Kuban·Mar 16, 2026
Identifying scalable materials systems that exhibit quantum behavior is a central challenge in quantum information science. Point defects in certain wide-bandgap semiconductors are promising in this regard due to the maturity of semiconductor manufac...
Measuring impurity-induced shifts in Coulomb crystallization
Mingyao Xu, Aaron A. Smith, Leonid Prokhorov +2 more·Mar 16, 2026
We report a laboratory measurement of how impurities shift Coulomb crystallization in a strongly interacting ionic system. This is achieved by using laser cooled Ca$^+$ crystals doped with a controlled number of Xe$^{12+}$ highly charged ions. We fin...
Engineering walk-off-induced orbital angular momentum spectrum in spontaneous parametric downconversion
Yang Xu, Robert W. Boyd·Mar 16, 2026
Spontaneous parametric downconversion (SPDC) has been considered as a reliable source of high- dimensional entangled states in orbital angular momentum (OAM) basis. In real-world experiments, the spatial walk-off of the pump often degrades the fideli...
Adaptive Control of Stochastic Error Accumulation in Fault-Tolerant Quantum Computation
Tirtha Haque·Mar 16, 2026
In realistic hardware for quantum computation that possesses fault-tolerance, non-stationary noise and stochastic drift lead to logical failure from the temporal accumulation of errors, not from independent events. Static decoding and fixed calibrati...
Quantum Enhanced Pauli Propagation
S. Majumder, J. R. Garrison, L. Luo +8 more·Mar 15, 2026
Accurately estimating observables on noisy quantum devices remains a central challenge for near-term quantum algorithms. While quantum error mitigation techniques can reduce noise-induced bias, they often rely on unverifiable assumptions about the ci...
Phase-preserving control of Floquet-engineered cavity quantum electrodynamics

We characterize single-mode vacuum squeezing generated by a SNAIL Parametric Amplifier (SPA) operated under conditions representative of practical sensing and qubit-readout experiments. Motivated by prior expectations that Kerr-induced distortion lim...
Analysis of Hydrogen Contamination in Al/AlOx/Al Josephson Junctions
Yu Zhu, Aldilene Saraiva-Souza, Félix Beaudoin +1 more·Mar 14, 2026
Hydrogen contamination in Josephson junctions is a potential source of device-to-device variability and two-level-system loss in superconducting qubits. In this work, we investigate hydrogen incorporation in oxidized aluminum barriers by combining mo...
Block-QAOA-Aware Detection with Parameter Transfer for Large-Scale MIMO
Shuai Zeng·Mar 14, 2026
Large-scale MIMO detection remains challenging because exact or near-maximum-likelihood search is difficult to scale, while available quantum resources are insufficient for directly solving full-size detection instances by QAOA. This paper therefore ...
Folding-Free Zero-Noise Extrapolation by Layout-induced Noise Diversity
Debarthi Pal, Yogesh Simmhan·Mar 14, 2026
Near term quantum processors operate in a noise dominated regime, motivating error mitigation techniques that recover accurate expectation values without full fault tolerance. Zero Noise Extrapolation (ZNE) is a widely used but biased error mitigatio...
