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…
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…
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…
Do You Need a PhD to Work in Quantum?
For most quantum jobs advertised today, a doctorate is not the entry requirement. Here is what is: the prerequisites that actually decide whether training…
The Skills Quantum Communications Work Requires
QKD deployment work sits across photonics, network protocol engineering, cryptography, and operations. Here is what each domain asks of an engineer, and where classical…
What It Takes to Build a Quantum Computer
A quantum computer is assembled by six engineering trades, only one of which is quantum physics. Here is what each of them does, and…
CNSA 2.0 Explained: A Compliance Reading for GRC Teams
CNSA 2.0 is the one post-quantum directive written like a control rather than a goal: named algorithms, fixed parameter levels, dated procurement gates. A…
How to Tell a Real Quantum Application From a Marketed One
Five industries have published evidence for quantum advantage. Roughly twenty do not. Three questions, asked in order, separate the two lists before any money…
What Early Quantum Buyers Are Actually Paying For
Current quantum computers can't beat a laptop on real work, yet governments and enterprises keep buying them. Which justifications hold up in a business…
The Helium-3 Problem in Quantum Computing, Explained
Helium-3 has no substitute for millikelvin cooling, and most quantum computers never touch it. A working guide to the physics, the supply chain, and…
