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 entangled photon pair generation from SiC-based microring resonator

October 4, 2022
Author(s)
Anouar Rahmouni, Lijun Ma, Xiao Tang, Thomas Gerrits, Lutong Cai, Qing Li, Oliver T. Slattery
Entangled photon sources are fundamental building blocks for quantum communication and quantum networks. Recently, silicon carbide emerged as a promising material for integrated quantum devices since it is CMOS compatible with favorable mechanical

Change Detection between XML Documents

October 12, 2021
Author(s)
K H. Lee, Y C. Choy, S B. Cho, Xiao Tang, V R. Mccrary
¿¿¿This paper presents an efficient algorithm to detect changes between old and new versions of an XML document. The difference between the two versions can be considered to be an edit script that transforms one document tree into another. The proposed

Content Migration: From Paper to XML Documents

October 12, 2021
