G., Steven Peil, Adam Black, David Tulchinsky, Alexander Hastings, YaShian Li-Baboud, Anouar Rahmouni, Paulina Kuo, Alan Mink, Ivan Burenkov, Yicheng Shi, Matthew Diaz, Nijil Lal Cheriya Koyyottummal, Mheni Merzouki, Pranish Shrestha, Alejandro Rodriguez Perez, Eleanya Onuma, Daniel Jones, Atiyya Davis, Thomas A. Searles, J.D. Whalen, Kate Collins, Qudsia Quraishi, La Vida Cooper, Harry Shaw, Bruce Crabill, Oliver Slattery, Abdella Battou
Quantum networking protocols relying on interference and precise time-of-flight measurements require high-precision clock synchronization. This study describes the design, implementation, and characterization of two optical time transfer methods in a

100-km entanglement distribution with coexisting quantum and classical signals in a single fiber

Anouar Rahmouni, Paulina Kuo, Ya-Shian Li-Baboud, Ivan Burenkov, Yicheng Shi, Jabir Marakkarakath Vadakkepurayil, Nijil Lal Cheriya Koyyottummal, Dileep Reddy, Mheni Merzouki, Lijun Ma, Abdella Battou, Sergey Polyakov, Oliver T. Slattery, Thomas Gerrits
The development of prototype metropolitan-scale quantum networks is underway and entails transmitting quantum information via single photons through deployed optical fibers spanning several tens of kilometers. Among the major challenges in metropolitan

Synchronized source of indistinguishable photons for quantum networks

Author(s)
Nijil Lal Cheriya Koyyottummal, Ivan Burenkov, Ya-Shian Li-Baboud, Jabir Marakkarakath Vadakkepurayil, Paulina Kuo, Thomas Gerrits, Oliver T. Slattery, Sergey Polyakov
We present a source of indistinguishable photons at telecom wavelength, synchronized to an external clock, for the use in distributed quantum networks. We characterize the indistinguishability of photons generated in independent parametric down-conversion

Single-photon Sources and Detectors Dictionary

September 7, 2023
Author(s)
Joshua Bienfang, Thomas Gerrits, Paulina Kuo, Alan Migdall, Sergey Polyakov, Oliver T. Slattery
The intention of this dictionary is to define relevant terms and metrics used in the characterization of single-photon detectors and sources with the goal to promote better understanding and communication of those metrics across the single-photon

Experimental demonstration of local area entanglement distribution between two distant nodes, coexisting with classical synchronization

Anouar Rahmouni, Paulina Kuo, Yicheng Shi, Jabir Marakkarakath Vadakkepurayil, Nijil Lal Cheriya Koyyottummal, Ivan Burenkov, Ya-Shian Li-Baboud, Mheni Merzouki, Abdella Battou, Sergey Polyakov, Oliver T. Slattery, Thomas Gerrits
We successfully demonstrated polarization entanglement distribution and classical time synchronization using a high-accuracy precision time protocol between two quantum nodes located 250 meters apart using a single fiber simultaneously carrying both

Sub-200 ps Quantum Network Node Synchronization over a 128 km Link White Rabbit Architecture

Author(s)
Wayne McKenzie, Ya-Shian Li-Baboud, Mark Morris, Gerald Baumgartner, Anouar Rahmouni, Paulina Kuo, Oliver T. Slattery, Bruce Crabill, Mheni Merzouki, Abdella Battou, Thomas Gerrits
We show sub-200 ps synchronization between quantum networks nodes that are separated by two 64 km deployed fiber links, providing a 128 km link architecture. The architecture employs one grandmaster and two boundary White Rabbit system clocks and shows

Portable polarization-entangled photon source & receiver toolset for quantum network metrology

October 4, 2022
Author(s)
Anouar Rahmouni, Thomas Gerrits, Paulina Kuo, Dileep Reddy, Lijun Ma, Xiao Tang, Oliver T. Slattery
A quantum network will consist of many physically separated nodes connected by quantum communication channels that distribute entanglement between them. Such nodes will require mechanisms for the generation, routing, and measurement of quantum states to

Towards a source of entangled photon pairs in gallium phosphide

May 9, 2019
Author(s)
Paulina S. Kuo, Peter G. Schunemann, Mackenzie Van Camp, Varun B. Verma, Thomas Gerrits, Sae Woo Nam, Richard P. Mirin
We investigate parametric down-conversion in orientation-patterned GaP. Pumped at 865 nm, the signal and idler are at 1350 nm and 2400 nm, respectively.

Generating polarization-entangled photon pairs in domain-engineered PPLN

Author(s)
Paulina S. Kuo, Varun B. Verma, Thomas Gerrits, Sae Woo Nam, Richard P. Mirin
Using a periodically poled LiNbO3 crystal that is domain-engineered for two simultaneous type-II down-conversion processes, we demonstrated polarization-entangled photon-pair generation.

Mixing of Polarization States in Zincblende Nonlinear Optical Crystals

October 2, 2018
Author(s)
Paulina S. Kuo, M. M. Fejer
We describe second-order nonlinear optical mixing in non-birefringent, zincblende-structure materials that can be quasi-phasematched. Lack of birefringence and quasi-phasematching together allow efficient nonlinear mixing between diverse polarization

Using Temperature to Reduce Noise in Quantum Frequency Conversion

May 12, 2018
Author(s)
Paulina Kuo, Jason S. Pelc, Carsten Langrock, M. M. Fejer
A main source of noise in quantum frequency conversion is spontaneous Raman scattering, which can be reduced by lowering the operating temperature. We show reduction in dark count rates that agrees well with theory.

Using Temperature to Reduce Noise in Quantum Frequency Conversion

April 23, 2018
Author(s)
Paulina S. Kuo, Jason S. Pelc, Carsten Langrock, M. M. Fejer
Quantum frequency conversion (QFC) is important in quantum networks to interface nodes operating at different wavelengths and to enable long-distance quantum communication using telecommunications wavelengths. Unfortunately, frequency conversion in actual
