Daniel Oblak

Assistant Professor

University of Calgary

Daniel Oblak is an Assistant Professor in the Department of Physics and Astronomy and principal investigator of the Quantum Cloud Lab. He is an expert on quantum memory in rare-earth ion doped materials, real-world quantum network realizations and more recently ground-to-satellite links. He was part of several important experimental demonstrations including the first storage of entanglement in a solid-state material, the development of a quantum repeater architecture based on spectral multiplexing, and quantum teleportation over a metropolitan fibre-network in Calgary. Dr. Oblak is part of the core science team of the Canadian Quantum Satellite mission QEYSSat and an affiliated researcher at the California Institute of Technology as part of the Intelligent Quantum Networks (INQNet) consortium. He is also the co-founder of a startup in quantum key distribution technology.

Talk Description

Quantum key distribution for hybrid encryption schemes

Our modern information society relies on secure and efficient encryption of data to be sent over public channels. Improvements in computational power, and in particular the anticipated deployment of quantum computers, will render much of the current encryption infrastructure insecure. Hence, new solutions that are impermeable to quantum computing attacks must be found. Quantum key distribution (QKD) is one of the strongest contenders to fill this role, as it can be proven to be information theoretically secure. However, to be efficient it must be paired with other encryption methods to form a hybrid encryption protocol. In the talk I will first present the basics and state of the art of QKD, followed by an overview of how QKD can be incorporated as a part of a hybrid encryption method. The hybrid protocol will be elaborated in a separate talk by another speaker.
