TQEC

Any good textbooks or other written resources to understand QEC well?

Video answer starting at 7'43" on this video.

1. Quantum Computation and Quantum Information [2010], aka "Mike and Ike": the "Bible" of Quantum Computing
2. TQEC for Computer Scientists [2024]. Aims to construct the surface code from first principles.
3. TQEC Project Wiki (here)
4. Mermin, Quantum Computer Science. A little gentler than Mike and Ike.
5. Fowler 2012 Surface Codes
6. Fowler/Gidney 2019, Lattice Surgery (what we primarily study in this group)
7. Gidney 2019 AutoCCZ

Would it be beneficial to take into account higher energy states to build better QEC codes?

Video answer starting at 9'27" on this video.

Short answer: no, such code would be harder to make and are not more powerful.

How does QEC guide hardware development and the other way around?

Video answer starting at 14'00" on this video.

Short answer: There is a two way interplay. QEC researchers try to develop codes that match available hardware. If you have physical long range interactions, then there are codes that require fewer qubits. Vice versa when a particular code looks especially promising, such as the surface code, this motivates hardware research to build devices optimized to implement the code.

I have known about your group recently. Didn’t get any introduction class but want to be kept updated with this group task and everything. So, how do I start?
