Field-Widened Multimode Interferometer with Long Time-Bin Delay Using a Multi-Pass Herriott Cell
Ramy Tannous, Stéphane Vinet, Kaylee Sherk +2
Interference of optical signals in free-space channels requires optical receivers to support many spatial modes due to atmospheric turbulence, typically necessitating adaptive opti…
All Reflective Field-widened Unbalanced Interferometer for Quantum Sensing and Communication Applications
Ramy Tannous, Dogan Sinar, Tabitha D. Arulpragasam +1
Interference of time-bin encoded signals over free-space optical channels typically requires stringent mode filtering on receivers due to wavefront distortions from atmospheric tur…
A reconfigurable entanglement distribution network suitable for connecting multiple ground nodes with a satellite
Stéphane Vinet, Ramy Tannous, Thomas Jennewein
Satellite-based quantum communication channels are important for ultra-long distances. Given the short duration of a satellite pass, it can be challenging to efficiently connect mu…
Storage of telecom wavelength heralded single photons in a fiber cavity quantum memory
K. A. G. Bonsma-Fisher, R. Tannous, D. Poitras +5
We demonstrate the storage and retrieval of heralded single photons in a fiber-based cavity quantum memory. The photons are stored, and retrieved, from the memory using quantum fre…
Toward deterministic sources: Photon generation in a fiber-cavity quantum memory
Philip J. Bustard, Ramy Tannous, Kent Bonsma-Fisher +5
We demonstrate the generation of photons within a fiber-cavity quantum memory, followed by later on-demand readout. Signal photons are generated by spontaneous four-wave mixing in…
Towards Fully Passive Time-Bin Quantum Key Distribution over Moving Free-Space Channels
Ramy Tannous, Wilson Wu, Stéphane Vinet +4
Encoding quantum information in photonic time-bin states is typically considered impractical for moving free-space quantum communication due to the difficulties with phase stabiliz…
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…
Repeated radiation damage and thermal annealing of avalanche photodiodes
Ian DSouza, Jean-Philippe Bourgoin, Brendon L. Higgins +6
Avalanche photodiodes (APDs) are well-suited for single-photon detection on quantum communication satellites as they are a mature technology with high detection efficiency without…
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…
