Capella Intelligent Subsystems, an industry leader when it comes to wavelength selective switch (WSS) technology, will team up with Boston University’s Quantum Communication and Measurement Laboratory (QCML) led by Professor Alexander Sergienko (ECE) in order to improve the next generation of telecommunications networks.

Sergienko’s research team already developed a high resolution technique that is used to evaluate very small polarization mode dispersion (PMD), which they tested using Capella’s WSS technology. Today, this technique is widely used to improve the efficiency of metropolitan networks.

“This new technology actively uses quantum entanglement and quantum optics to beat existing classical counterparts in resolution,” explained Sergienko.

In a press release, Capella said: “This research highlights the high-resolution measurements made possible by quantum photonic techniques and validates the benefit of collaboration between industry leaders, such as Capella, and university research teams.”

Roman Egorov, a Ph.D. candidate working in the QCML, said the developments they’re working on for Capella will help meet long-term telecommunications demands.

“Our team approached Capella with this project because of their team’s capability to take the research results to product deployment in the field,” said Egorov.

Sergienko’s laboratory already received about $200,000 from Capella for their initial research and will receive more in the future. This is the first time in quantum research that a telecommunications company has paid cash for university quantum optics development.

“Not many companies could support research at this scale so we are grateful for their partnership and support,” said Sergienko.

In their press release, Capella said that the need for PMD measurements will only increase as more demand is placed on high-speed fiber optic networks. Accurate readings are critical for controlling the performance of telecommunications.

“The need for even greater resolution measurement will grow with the deployment of next generation telecom standards in excess of 100 gigabytes per second in the very near future,” added Sergienko. “Only quantum measurement will be able to deliver.”
