More precisely, we focus on a class of prepare-and-measure protocols based on the Bennett-Brassard (BB84) protocol as well as a class of entanglement-based protocols similar to the Bennett-Brassard-Mermin (BBM92) protocol.
We carefully formalize the different steps in these protocols, including randomization, measurement, parameter estimation, error correction and privacy amplification, allowing us to be mathematically precise throughout the security analysis.

Our results significantly improve upon previously reported tradeoffs.
https://doi.org/10.1103/Phys Rev Lett.67.661  C. We address this challenge by using high-dimensional encoding to increase the secure information yield per detected photon.In this thesis, we present security analysis for and the first demonstrations of a resource-efficient high-dimensional QKD protocol, including two varieties of implementation that each have different strengths and weaknesses. https://doi.org/10.1038/nphoton.2016.50  P. Experimental demonstration of long-distance continuous-variable quantum key distribution. https://doi.org/10.1038/nphoton.2013.63  M. Tight Finite-Key Analysis for Quantum Cryptography. We start from an operational definition of what it means for a quantum key distribution protocol to be secure and derive simple conditions that serve as sufficient condition for secrecy and correctness. We then derive and eventually discuss tradeoff relations between the block length of the classical computation, the noise tolerance, the secret key length and the security parameters for our protocols.
