Will Quantum Computers Replace Classical Computers?
No. Every quantum processor depends on classical computers to compile its programs, generate its control signals and read its results. Here's which jobs belong…
Retiring SHA-1 Took More Than a Decade: Lessons for Post-Quantum Planning
Retiring SHA-1 took the public web almost 12 years, and NIST's end date for every use is December 31, 2030. Post-quantum planners can learn…
What Is Superposition? Amplitudes, Phase and the Bloch Sphere
Superposition means a qubit's state is described by two amplitudes. Their squares give the odds of reading 0 or 1, and what a Hadamard…
Is Anything Unhackable? Reading Absolute Security Claims
No standard defines "unhackable", and no certification scheme awards it. Ask three questions instead: under which threat model, proven or tested by whom, and…
How to Check Whether a TLS Connection Is Already Post-Quantum
Your browser, openssl s_client and curl can all show whether a connection negotiated X25519MLKEM768. Here's where to read the group name, what hybrid key…
Public-Key and Symmetric Cryptography: Which Half a Quantum Computer Breaks
A quantum computer running Shor's algorithm would break RSA, Diffie-Hellman and elliptic-curve cryptography. AES and SHA-2 only lose some margin to Grover's algorithm. Here's…
How to Use the PQC Readiness Scorecard
The PQC Readiness Scorecard rates an organization's post-quantum readiness in seven domains and shows the evidence behind each answer. This guide explains the scoring…
Seven Exercises – PQC Migration Advisor
Seven exercises with the free PQC Migration Advisor, from sorting algorithms by quantum exposure to hybrid TLS under CNSA 2.0 and deadlines by legal…
How use PQC Migration Budget Builder
A step-by-step walkthrough of the PQC Migration Budget Builder: what to prepare, what each of the five steps asks for, a mid-size payments example,…
How Quantum Academy uses AI, and why we put live teaching first
We use AI to research, draft and edit our material. People decide what we teach, experts check it, and our instructors teach every live…
