On-chip indistinguishable photons using III-V nanowire/SiN hybrid integration
Edith Yeung, David B. Northeast, Jeongwan Jin +5
We demonstrate on-chip generation of indistinguishable photons based on a nanowire quantum dot. From a growth substrate containing arrays of positioned-controlled single dot nanowi…
Hong-Ou-Mandel interference of unconventional temporal laser modes
Sascha Agne, Jeongwan Jin, Katanya B. Kuntz +3
The Hong-Ou-Mandel (HOM) effect ranks among the most notable quantum interference phenomena, and is central to many applications in quantum technologies. The fundamental effect app…
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…
Best Fidelity Conditions for Three Party Quantum Teleportation
Sangjin Sim, Jeongwan Jin, Younghun Kwon
Using the entangled three qubit states classified by Acin et al. we find the best fidelity conditions for quantum teleportation among three parties.
