Many useful quantum algorithms require logical qubits with operations that have errors less than one part per billion. Fault-tolerant protocols based on quantum error correction are algorithms for creating high-fidelity qubits and operations from low-fidelity parts. In this talk, I will describe recent joint work with the University of Maryland implementing the Bacon-Shor quantum error correction code (arXiv:2009.11482). The talk will start with a review of quantum error correction and explain the importance of developing fault-tolerant procedures. I will then focus on compass codes and the interplay between hardware specifics and choice of error correcting code. After discussing current quantum error correction experiments, I will provide an outlook for the next steps towards implementing scalable, fault-tolerant quantum computers.
