Tasshi Dennis (Fed)

Tasshi Dennis is the leader of the Quantum Networking and Transduction Group within the Communications Technology Laboratory (CTL) in Boulder, CO. For more than 25 years, Dr. Dennis has been involved with a diverse array of research projects that has included optical fiber communications, wavelength standards, high-speed photodetector metrology, electro-optic sampling methods, all-optical sampling, biomedical imaging, and photovoltaic device characterization. As a group leader within the Quantum Communications Division of CTL, he has been applying his decades of research experience with classical optical networks and their development during the telecom boom to the quantum realm. His group is attempting to build the optical interconnects to network individual superconducting quantum computers to allow them to scale in processing power and increase in functionality. The approach involves developing vibrating membrane quantum transducers which quantum mechanically connect the microwave processing domain with the optical transmission domain to establish remote microwave entanglement between the nodes of the network. His group has been successful in determining how best to implement a network of superconducting quantum nodes connected by optical channels in the face of realistic signal loss and added noise. As an experimentalist, Dr. Dennis and his team are actively designing and fabricating quantum transducers, characterizing transducer properties and developing qubit interaction protocols, and constructing optical sources of quantum entanglement.

Dr. Dennis is also an expert on the implementation of quality management systems for measurement services conforming to international standard ISO/IEC 17025 and has serviced as the Quality Manager of the RF Technology Division of CTL.  He is a senior member of the Optical Society of America and adjoint faculty in the Physics and Electrical, Computer, and Energy Engineering Departments at the University of Colorado - Boulder.
