Positive stabilization of a pure diffusion system
Violaine Piengeon, Joseph J. Winkin
This paper provides a complete analytical study of the positive stabilization, positive state estimation, and observer-based positive stabilization problems for a generic boundary…
Compressive Spectrum Sensing via Spectral Multiplexing in Rydberg Atomic Receiver
Jun-Rong Chen, Yi-Ming Yin, Le-Bin Chen +7
Rydberg-atomic receivers exhibit exceptional sensitivity yet are fundamentally constrained by the narrow instantaneous bandwidth, limiting their practical deployment in broadband s…
3D imaging of the biphoton spatiotemporal wave packet
Yang Xue, Ze-Shan He, Hao-Shu Tian +6
Photons are among the most important carriers of quantum information owing to their rich degrees of freedom (DoFs), including various spatiotemporal structures. The ability to char…
Enhanced multi-parameter metrology in dissipative Rydberg atom time crystals
Bang Liu, Jun-Rong Chen, Yu Ma +10
The pursuit of unprecedented sensitivity in quantum enhanced metrology has spurred interest in non-equilibrium quantum phases of matter and their symmetry breaking. In particular,…
A mechanical quantum memory for microwave photons
Alkım B. Bozkurt, Omid Golami, Yue Yu +2
Long-lived mechanical oscillators are actively pursued as critical resources for quantum storage, sensing, and transduction. However, achieving deterministic quantum control while…
