Risultati finali

Report on electrical characterization (si apre in una nuova finestra)

Systematic electrical characterisation of quick turn monitors will be carried out by the different characterisation teams according to specific expertise, scientific interest and existing collaborations. Definition of a set of common metrics and targets will facilitate knowledge exchange and accelerate progress.

Gate set protocol for fault tolerant operation (si apre in una nuova finestra)

Randomized benchmarking measurements will be performed on quantum dot arrays in order to obtain insight into fidelity and its variability from qubit to qubit. On the theory side we are going to model electron-phonon, hyperfine, spin-orbit interaction and charge noise in order to understand their effect on qubit benchmarks. The goal is to enable the interpretation of experiments and to provide feedback and guidelines for optimized device design.

Qubit realization exceeding quality factors of 500 (si apre in una nuova finestra)

Characterization of spin coherence (T1,T2*,T2) and Rabi driving (optimial driving, role of spin-orbit coupling) in connection to qubit layout.

Feedback on qubit properties (si apre in una nuova finestra)

WP3,4 will provide regular feedback on qubit benchmarking. This feedback will complete the learning cycle on materials and devices development and provide guidelines for design and process optimization.

Open-source shared training sets for quantum dot control machine learning algorithms (si apre in una nuova finestra)

Use system-specific theoretical models produced in WP3 to generate labeled data sets for classically simulatable system sizes (< 12 quantum dots)* Develop geometric graph-based translationally invariant machine learning models and benchmark them on the theoretically generated data sets.

Annual report (si apre in una nuova finestra)

Annual report with latest material developments and resources information. Also month 24 and 36.

IGNITE website (si apre in una nuova finestra)

Creation of IGNITE website: central platform for communication

Germanium workshop and conference (si apre in una nuova finestra)

Also in month 30.Coordinating the organization of the Germanium Day in Austria (IST) and 'The germanium quantum information route' conference (UKON) together with all IGNITE WPs, an event to showcase the milestones and achievements of IGNITE - (UKON, IST, all)
