Cluster-State Quantum Error Correction Based on AdS/CFT
Abstract
This project aimed to develop the theory around the highly nonlinear saddle point qubit. The proposed device has been named a dualmon in the literature, and this nomenclature has been adopted by other practitioners in the field. The aims of this project were to1. Develop realistic saddle-point qubit models to assess performance against classical noise.2. Extend the model to include open quantum systems dynamics, to assess performance against quantum noise.3. Analyse state preparation protocols to measure and produce arbitrary single qubit states.4. Develop feedback protocols to implement active error correction.5. Develop protocols for coupling two saddle-point qubits.The theoretical research program has largely completed aims 1-3, reported in publications [1] and [2]. Aims 4 and 5 were not completed. This work has taken longer than expected, largely due to unanticipated complexity in developing these models. This has emerged from a realization that a full understanding of the processes required toimplement gates on superconducting devices will depend on a more detailed microscopic model of hybrid superconducting semiconducting systems, which has been the focus of Steigmanns approach.Overall the results were positive and the project largely successful.
