High-Throughput Microwave Package for Precise Superconducting Device Measurement
Wei-Ren Syong, Allie Miller, Emma Davis +6 more·Dec 20, 2025
Cryogenic microwave measurement of superconducting quantum devices is complicated by the packaging required to connect devices to control and readout circuitry. In this work, we outline the design and experimental demonstration of a wirebond-free, PC...
Kerr-induced non-Gaussianity of ultrafast bright squeezed vacuum
Andrei Rasputnyi, Ilya Karuseichyk, Gerd Leuchs +2 more·Dec 19, 2025
Non-Gaussian states of light are a critical resource for fault-tolerant quantum computing and enhanced metrology, but are typically faint and often obtained via post-selection. Here, we demonstrate the deterministic generation of a bright non-Gaussia...
Microcomb-driven large-scale fully connected quantum network
Fang-Xiang Wang, Sheng-Teng Zheng, Long Huang +15 more·Dec 19, 2025
Fully connected quantum networks enable simultaneously connecting every user to every other user and are the most versatile and robust networking architecture. However, the scalability of such networks remains great challenge for practical applicatio...
Zero-added-loss entanglement multiplexing using time-bin spectral shearing
Joseph C. Chapman, Muneer Alshowkan, Jack Postlewaite +2 more·Dec 19, 2025
High-quality quantum communications that enable important capabilities, such as distributed quantum computing and sensing, will require quantum repeaters for providing high-quality entanglement. To realize high-rate heralded entanglement for quantum ...
Comparing Homodyne and Heterodyne Tomography of Quantum States of Light
Rhea P. Fernandes, Andrew J. Pizzimenti, Christos N. Gagatsos +1 more·Dec 18, 2025
Non-Gaussian quantum states are critical resources in photonic quantum information processing, rendering their generation and characterization of increasing importance in quantum optics. In this work, we theoretically and numerically analyze the rela...
Model-Based Real-Time Synthesis of Acousto-Optically Generated Laser-Beam Patterns and Tweezer Arrays
