Quantum Computers Look Like Chandeliers. This is Why.
Whether you saw a quantum computer featured in a tech news blog post, or that Black Mirror episode "Joan is Awful", the chandelier-like look may have inspired the thought "Why does it look like that?" Well, it's not for the sci-fi...

Why Quantum Computing Requires Quantum Cryptography
Quantum computing is cool, but you know what would be extra awesome - a quantum internet. In fact if we want the first we’ll need the latter. And the first step to the quantum internet is quantum cryptography.
