Experimental and theoretical demonstration of the feasibility of global quantum cryptography using satellites
(University of Waterloo, 2014-10-15)Information security is a growing concern in our modern world, where almost everything can be done online. To protect security, classical encryption protocols, such as RSA, are used. These encryption protocols are almost ... -
Experimental quantum communication in demanding regimes
(University of Waterloo, 2011-08-02)Quantum communication promises to outperform its classical counterparts and enable protocols previously impossible. Specifically, quantum key distribution (QKD) allows a cryptographic key to be shared between distant parties ... -
On Free Space Quantum Key Distribution and its Implementation with a Polarization-Entangled Parametric Down Conversion Source
(University of Waterloo, 2007-05-16)This thesis describes the deployment of a free-space quantum key distribution system across the University of Waterloo campus. The quantum key distribution system has the ability to provide unconditionally secure ... -
Pre-Privacy Amplification: A Post-Processing Technique for Quantum Key Distribution with Application to the Simplified Trusted Relay
(University of Waterloo, 2023-04-26)Until quantum repeaters and quantum error correcting codes can be made commercially viable, long distance quantum key distribution (QKD) will continue to rely on trusted relay satellites. Strongly constrained by weight ... -
Techniques for Improving Numerical Secret Key Rates of Quantum Key Distribution Protocols
(University of Waterloo, 2023-10-24)Quantum Key Distribution (QKD) is a method for producing secure keys between two parties whose security does not rely on computational assumptions potentially breakable by quantum computers. However, physical constraints, ...
