The focus on the latter will be on practical examples that can be realized today or in the near future with a modular architecture based on superconducting electrical circuits and microwave photons. The goal and vision is 'hardware-efficient' quantum error correction that does not require exponentially large hardware overhead in order to achieve practical and useful levels of fault tolerance and circuit depth.", "revisions": [ { "version": "v2", "updated": "2022-03-26T02:32:43.000Z" } ], "analyses": { "keywords": [ "quantum error correction", "fault tolerance", "introduction", "quantum information machines", "houches summer school" ], "tags": [ "lecture notes" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
