The mathematics of useless quantum channels
Please find the slides from the seminar (pdf).
When studying quantum information processing tasks in theory we often assume idealized quantum devices that are only affected by relatively low levels of noise.
In my talk I want to focus on the other end of the spectrum where the noise levels are high. For different information processing tasks (including sharing of entanglement, quantum communication and private communication in repeater settings).
I will review recent mathematical results on the properties and structure of noise processes rendering these tasks impossible.
Finally, I will give an outlook on several open problems in this area of quantum information theory.
About the qGAP meeting series
Welcome to qGAP, our seminar series on Quantum Physics and Quantum Technology.
The series of seminars/lectures are meant to cover broadly activities at UiO and elsewhere related to quantum physics and technologies, mainly from a theoretical perspective, though we also welcome experimental talks.
We aim at having regular seminars, discussions of recent articles, presentations by master and PhD students and more. We aim for this series to be a combination of research talks and journal clubs.
Educational topics are also most welcome.
Please feel free to suggest speakers, yourself included!
Get in touch with Gunnar Lange to suggest a speaker or if you would like to be included in the mailing list.
All are welcome!
