Post Quantum Cryptography

The shiny round thing above is a 300mm silicon wafer containing IBMs new Nighthawk R3 quantum CPU. It’ll be available next year, and will provide quantum systems capable of handling more than 1,000 qubits. Which is quite a lot. That these exist as a chip you can buy, rather than an exotic gadget plumbed out of stainless steel is a sign that quantum computers are a real thing.
