A post going over the current post-quantum cryptography landscape, including the current NIST standardization efforts and the underlying mathematical approaches to selected algorithms. This second post in the PQC series sets the groundwork for the practical exploration using experimental branches in the upcoming third post.

A post going over the theoretical implementation of Shor's algorithm as well as covering a previous Qiskit challenge that involved practically implementing Shor's to factor the number 35. This will lay the groundwork to further posts exploring the need for post-quantum cryptography and implementations so far.

Have you ever cleaned a heavy piece of machinery with a hand-held vacuum? What is a Canadian summer without another HVAC issue! Let's dive into a new error that popped up recently leaving me two weeks without cooling, and what I learned from it!

Walkthrough of NSEC 2023's two N64 ROM challenges. This post will cover the ROM analysis, including loading into Ghidra, extracting debug symbols from a separately provided file, and then stepping through the logic loop to determine the right input. Ultimately the challenge was solved using a memory buffer overflow arbitrarily calling the printflag() function.

Overview and walkthrough of the Xadanu QHACK 2023 Fall of Sqynet Track. Five challenges increasing in difficulty with a focus Ising Hamiltonians and QML to train a series of circuits on unknown grading input to within a tolerance.

Overview and walkthrough of the IBM Qiskit Fall 2022 Quantum Challenge which had a focus on Qiskit runtime and the primitives sampler and estimator. This post will cover how the challenges were solved and lessons learned.
