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 ... -
An Exploration of Secure Circular Multi-Party Quantum Computation
(University of Waterloo, 2022-09-26)Multi party quantum computation (MPQC) is any quantum cryptographic protocol where multiple untrusted users collaborate to perform calculations on their combined data without revealing their private information. MPQC is ... -
Numerical Finite Key Analysis
(University of Waterloo, 2020-09-02)In this thesis, we begin by both expounding and improving the theory of finite key analysis. Our improvement of the analysis in turn improves the amount of key that can be generated for protocols without nice symmetries. ... -
Optical Quantum Communication & Cryptography with Temporarily Trusted Parties
(University of Waterloo, 2019-09-19)The work in this thesis can be divided into three parts. The first two parts deal with optical quantum communication protocols and the third part deals with quantum cryptography. The first part of the thesis is a step ... -
Practical Quantum Communication
(University of Waterloo, 2015-10-30)Current communication networks are based on classical physics and classical information-processing. However, for nearly a century, we have known that at its most fundamental level, the universe is governed by the laws of ... -
Security Evaluation of Practical Quantum Communication Systems
(University of Waterloo, 2017-09-29)Modern information and communication technology (ICT), including internet, smart phones, cloud computing, global positioning system, e-commerce, e-Health, global communications and internet of things (IoT), all rely ...
