Experimental Quantum Key Distribution at 1.3 Gbit/s Secret-Key Rate over a 10-dB-Loss Channel
Zheshen Zhang, Changchen Chen, Quntao Zhuang +2
Quantum key distribution (QKD) enables unconditionally secure communication ensured by the laws of physics, opening a promising route to security infrastructure for the coming age…
Exploiting Occlusion in Non-Line-of-Sight Active Imaging
Christos Thrampoulidis, Gal Shulkind, Feihu Xu +5
Active non-line-of-sight imaging systems are of growing interest for diverse applications. The most commonly proposed approaches to date rely on exploiting time-resolved measuremen…
Distributed Quantum Sensing Using Continuous-Variable Multipartite Entanglement
Quntao Zhuang, Zheshen Zhang, Jeffrey H. Shapiro
Distributed quantum sensing uses quantum correlations between multiple sensors to enhance the measurement of unknown parameters beyond the limits of unentangled systems. We describ…
Hardware-Efficient Bosonic Quantum Error-Correcting Codes Based on Symmetry Operators
Murphy Yuezhen Niu, Isaac L. Chuang, Jeffrey H. Shapiro
We establish a symmetry-operator framework for designing quantum error correcting~(QEC) codes based on fundamental properties of the underlying system dynamics. Based on this frame…
Quantum illumination for enhanced detection of Rayleigh-fading targets
Quntao Zhuang, Zheshen Zhang, Jeffrey H. Shapiro
Quantum illumination (QI) is an entanglement-enhanced sensing system whose performance advantage over a comparable classical system survives its usage in an entanglement-breaking s…
Entanglement-Enhanced Lidars for Simultaneous Range and Velocity Measurements
Quntao Zhuang, Zheshen Zhang, Jeffrey H. Shapiro
Lidar is a well known optical technology for measuring a target's range and radial velocity. We describe two lidar systems that use entanglement between transmitted signals and ret…
