C12 develops reliable & application-specific quantum computers, to solve highly complex computing tasks, currently out of reach of even most powerful supercomputers. C12 uniquely uses carbon nanotubes as the fundamental building blocks of its quantum processor. This high-purity material minimizes errors, radically improves performance and reduces hardware overhead for fault-tolerant computing.
Job Responsibility:
Contributing to the design & optimization of passive on-chip distributed RF circuits for qubit control and performing & analyzing microwave simulations
Developing, with research scientists and other hardware engineers, microwave simulations for the on-chip RF circuits and its 3D packaging
Identifying cross-talks and loss mechanisms in RF circuits
Investigating discrepancies between simulated and achieved performance of fabricated devices
Develop a scalable architecture for routing the microwave signal (very low power) towards and between >100 qubits
Contributing to the continuous improvement of our simulation tools and their integration with Python-based custom layout/design tools
Requirements:
Minimum 5+ years experience as an RF engineer
Experience developing electromagnetic simulations using industry standard tools such as HFSS, Maxwell, Comsol, or Cadence
Experience with designing and integrating microwave components and subsystems
Experience with high-frequency (RF, microwave or mm-wave), IC or PCB design
Experience with design/development in Python
Good communication in English (verbal and written)
Nice to have:
Experience in designing superconducting resonator is seen as an advantage
Knowledge of semiconductor device physics and microfabrication processes is seen as an advantage
Knowledge of fabrication principles and the constraints they impose on physical device parameters is seen as an advantage
