End-to-End Quantum Key Distribution Across Hybrid Fiber and Free-Space Links with All-Optical Encoding Conversion
Khen Cohen, Tomer Nahum, Michael Tzukran +6
Quantum key distribution (QKD) promises information-theoretically secure communication, but future networks must bridge fiber and free-space links that naturally employ different p…
Distributed Acoustic Sensing for Urban Monitoring: Coverage Thresholds and Percolation
Khen Cohen, Ariel Lellouch
Distributed Acoustic Sensing (DAS) enables the repurposing of existing fiber-optic networks as ultra-dense, long-range seismic arrays for urban monitoring. However, constraints imp…
Boson Sampling as a Probe of Chaotic and Integrable Quantum Dynamics in a Photonic Chip
Yuancheng Zhan, Khen Cohen, Norman T. W. Koo +8
Quantum chaos plays a key role in understanding complex quantum dynamics, while integrated photonics offers unique advantages for quantum applications, including high-speed operati…
Implicit Binarization via Complex Phase Dynamics in Combinatorial Optimization
Khen Cohen, Mark Glass, Meir Feder +1
We introduce a physics-inspired continuous relaxation framework that yields substantially improved solutions for NP-hard combinatorial optimization problems, including Quadratic Un…
Single Plane Spatial Mode Sorter
Khen Cohen, Yoav Yosif-Or, Yaron Oz +1
A mode sorter separates a set of M orthogonal spatial modes in a shared input channel into M different output channels. Here we present an analytic derivation and experimental vali…
