Sagnac-type entangled photon source using only conventional polarization optics
Youn Seok Lee, Mengyu Xie, Ramy Tannous +1
We designed and implemented a novel combination of a Sagnac-interferometer with a Mach-Zehnder interferometer for a source of polarization-entangled photons. The new versatile conf…

Demonstration of a 6 State-4 State Reference Frame Independent channel for Quantum Key Distribution
Ramy Tannous, Zhangdong Ye, Jeongwan Jin +3
We study a novel protocol for reference frame independent (RFI) quantum key distribution (QKD) using six states for Alice and four states for Bob, while previous RFI protocols requ…

Genuine time-bin-encoded quantum key distribution over a turbulent depolarizing free-space channel
Jeongwan Jin, Jean-Philippe Bourgoin, Ramy Tannous +5
Despite its widespread use in fiber optics, encoding quantum information in photonic time-bin states is usually considered impractical for free-space quantum communication as turbu…
