Rydberg quantum antennas for chip-interfaced single-photon source array
Yan-Lei Zhang, Dong-Qi Ma, Guang-Jie Chen +6
We propose a Rydberg quantum antenna, consisting of a one-dimensional chain of neutral atoms trapped in a standing-wave optical tweezer, as a chip-interfaced single-photon source.…
Hundred-hertz quantum circuit iteration rate in a reusable neutral-atom array
Liang Chen, Wen-Yi Zhu, Dong-Qi Ma +16
Neutral-atom quantum processors have rapidly advanced in scale and coherence, yet their practical performance remains constrained by limited quantum circuit iteration rates (qCIRs)…
A scalable chip-integrated single-photon source array based on 50 individually addressable neutral atoms
Ya-Dong Hu, Tian-Yang Zhang, Dong-Qi Ma +10
Scalable arrays of identical single-photon sources are a central resource for photonic quantum information processing, quantum networks and quantum metrology. Neutral atoms provide…
Low-latency FPGA-based electronic control system for fast preparation of defect-free atom arrays
Ya-Dong Hu, Dong-Qi Ma, Tian-Yang Zhang +13
The scalability of neutral atom quantum computing demands integrated electronic control systems with low latency, modular architecture, and real-time feedback capability. Here, we…
Echoed Random Quantum Metrology
Dong-Sheng Liu, Zi-Jie Chen, Ziyue Hua +8
Quantum metrology typically demands the preparation of exotic quantum probe states, such as entangled or squeezed states, to surpass classical limits. However, the need for careful…
