This is the seventh post in a series on quantum error correction. For other parts, check out the link at the bottom. The Toric Code so far We have a bunch of qubits, which we call physical qubits. These are too noisy to do anything useful. …

This is the sixth post in a series on quantum error correction. For other parts, check out the link at the bottom. Last time we introduced the toric code, which is a way of making many noisy qubits (which we called physical qubits) into one with hardly any noise at…

This is the fifth post in a series on quantum error correction. For other parts, check out the link at the bottom. We want to build a quantum computer. For that we need quantum bits or qubits. The ones we can build will always be too noisy to be used…

This is the fourth post in a series on quantum error correction. For other parts, check out the link at the bottom. In the next set of posts we will be moving on to the promised land: we will start looking at surface codes. These were everyone’s favourite codes back…

This is the third post in a series on quantum error correction. For other parts, check out the link at the bottom. We have some information. We want to store it for a long time without it getting messed up. As we saw in the first part, that’s not problem. 1. What is Quantum Error Correction? 5 years ago I had ran a citizen science project based on quantum computing. More specifically it was based on quantum…decodoku.medium.com

This is the second post in a series on quantum error correction. For other parts, check out the link at the bottom. When storing and processing digital information, we use binary. Everything is expressed as strings of 0s and 1s. Though these are simple units of information, there is a…

5 years ago I had ran a citizen science project based on quantum computing. More specifically it was based on quantum error correction, which is how we plan to help quantum computers solve problems despite the effects of imperfections. …

This is the transcript of a talk given at the PCG workshop at the FDG 2020 conference. You can find the paper it’s based on here. It’s all about procedural generation, which is basically making content (like terrain, levels, puzzles, etc) for things that need content (like games). I’m James…

This is the blog version of a talk given at the IEEE Conference on Games 2020. Each slide is followed by what I say during that slide in the talk. You can find the paper here. Hi, I’m James Wootton. I work at IBM Research. We build quantum computers and…
