A Testbed for Quantum Communication and Quantum Networks

May 13, 2019
Author(s)
Lijun Ma, Abdella Battou, Xiao Tang, Oliver T. Slattery
The development of Quantum Networks is underway with significant acceleration in in recent years. Meanwhile. quantum scale devices and components such as single photon sources, detectors, memories and interfaces are ever readier to leave the laboratory

Noise Reduction in Optically Controlled Quantum Memory

May 7, 2018
Author(s)
Lijun Ma, Oliver T. Slattery, Xiao Tang
Quantum memory is an essential device for quantum communications systems and quantum computers. An important category of quantum memory, called Optically controlled quantum memory, uses a strong classical beam to control the storage and re-emission of a

Optical quantum memory based on electromagnetically induced transparency

February 20, 2017
Author(s)
Lijun Ma, Oliver T. Slattery, Xiao Tang
Electromagnetically induced transparency (EIT) is a promising approach to implement quantum memory in quantum communication and quantum computing applications. In this paper, following a brief overview of the main approaches to quantum memory, we provide

Comparing the Linewidths from Single-Pass SPDC and Singly-Resonant Cavity SPDC

September 3, 2015
Author(s)
Oliver T. Slattery, Lijun Ma, Paulina S. Kuo, Xiao Tang
Spontaneous parametric down-conversion (SPDC) is a common method to generate entangled photon pairs for use in quantum communications. The generated single photon linewidth is a critical issue for photon-atom interactions in quantum memory applications. We

EIT Quantum Memory with Cs Atomic Vapor for Quantum Communication

September 1, 2015
Author(s)
Lijun Ma, Oliver T. Slattery, Paulina S. Kuo, Xiao Tang
Quantum memory is a key device in the implementation of quantum repeaters for quantum communications and quantum networks. We demonstrated a quantum memory based on electromagnetically-induced transparency (EIT) in a warm cesium atomic cell. The quantum

Entangled photon generation in a phase-modulated, quasi-phasematched crystal

October 14, 2013
Author(s)
Paulina S. Kuo, Jason S. Pelc, Oliver T. Slattery, Yong-Su Kim, Xiao Tang
We propose a scheme to generate polarization-entangled photon pairs by spontaneous parametric downconversion in a phase-modulated, type-II, quasi-phasematched (QPM) crystal. Instead of using two distinct crystals to generate |HV>and |VH> states, the phase

Spectral response of an upconversion detector and spectrometer

September 17, 2013
Author(s)
Paulina S. Kuo, Oliver T. Slattery, Yong-Su Kim, Jason S. Pelc, M. M. Fejer, Xiao Tang
We theoretically and experimentally investigate the spectral response of an upconversion detector and discuss implications for its use as an infrared spectrometer. Upconversion detection is based on high-conversion-efficiency sum-frequency generation (SFG)
