Work package 4
Validation for Metrology and industrialization
Task 1
Led by LNE
Metrological validation of the SI standards
UCL will perform numerical simulations to reduce the spectrum of angles to explore in twisted devices.
Home-made codes have been developed based on the Green’s function formalism in order to investigate
the electronic and quantum transport properties of twisted bilayer graphene systems with a number of
atoms up to the order of 105, thus being able to reach the size of experimental devices. We propose
to rely on these numerical simulations to find efficiently the best range of angular alignment that will
give rise to QAHE and superconductivity phenomena.
Task 3
Led by LNE
Promotion of the measurement methods developed in FLATS to the metrology community
With input from all partners, LNE will publish guidelines and good practice guides to validate the
outputs of the twistronics paltform as new references for quantum metrology beyond the SI. Promotion
in the international metrology community (CIPM, EURAMET, etc) will be done.
Task 4
Led by AMO
Integration with ”classical” electronics
With input from CEA and LNE, AMO will concept a prototype integrating a QAH device and
a MZI with ”classical” electronics. This prototype aims to demonstrate on-chip combination of the
quantum standards and sensors. AMO will moreover demonstrate a new way of integrating two-
dimensional (2D) materials into semiconductor manufacturing lines that will be compatible with high-
volume manufacturing on wafer level.
