The UCF Mathematics and Applications Seminar, which takes place every Friday from 10:30am to 11:30am in MSB 318, provides a venue for researchers to present their current work, foster new collaborations, and showcase both foundational mathematics and its applications to graduate and undergraduate students.
Dr. Deguang Han will be speaking at this seminar about some measurement problems for quantum channels.
Abstract: Phaseless signal recovering has gone through a vast development period in the last decade due to its close connections with many areas of research including frame theory, lower-rank matrix recovering and quantum information theory. In quantum information theory, a quantum channel is a completely positive and trace-preserving linear map between matrix algebras that transmits quantum information as well as classical information. In this talk I will briefly discuss some (phaseless, of course) measurement problems for quantum channels, and present a few simple results related to their phase retrievabilities. This talk is accessible to advanced undergraduate math majors.
