Extensible universal photonic quantum computing with nonlinearity
Shang Yu, Jinzhao Sun, Kuan-Cheng Chen +17 more·Feb 6, 2026
Universal quantum computing requires an architecture that supports both linear circuits and, crucially, strong nonlinear resources. For quantum photonic systems, integrating such nonlinearities with scalable linear circuitry has been a major bottlene...
Semi-Device-Independent Quantum Random Number Generator Resistant to General Attacks
Zhenguo Lu, Jundong Wu, Yu Zhang +4 more·Feb 6, 2026
Quantum random number generators (QRNGs) produce true random numbers based on the inherent randomness of quantum theory, rendering them a foundational segment of quantum cryptography. Distinguished from trusted-device QRNGs whose security depends on ...
Quantum simulation of the Dicke model in a two-dimensional ion crystal: chaos, quantum thermalization, and revivals
Bryce Bullock, Sean R. Muleady, Jennifer F. Lilieholm +6 more·Feb 5, 2026
Quantum many-body systems driven far from equilibrium can exhibit chaos, entanglement, and non-classical correlations, yet directly observing these phenomena in large, closed quantum systems remains challenging. Here we realize the Dicke model -- a f...
