Fast event distribution over a HW-parametric large-scale control system, Part 2

Many aspects of quantum computing are under active research, from improvements in qubit quality to the discovery of new applications, and including the classical electronics and software part of the control system. The changes will mean that the quantum computing stack will require fundamental re-designs for the next generation. Major differences in the control requirements of various qubit types also contribute greatly to the complexity of designing a universal control system.

Since most of the stack’s core functionality is digital supported by telecom sector-led advances in D/A converter and digital signal processing technologies - to the exception of front-end analog electronics - highly parametric IP can be designed to support a wider range of qubit types and applications.

We describe the core architecture of a control system which, combined with the use of FPGAs, allows to easily re-configure the system to suit a particular QPU architecture. We further demonstrate how our IP for time-deterministic instructions sequencing and signal generation provides enough flexibility to perform advanced quantum computing experiments. Finally we describe our approach to compilation aiming to abstract away the complexity of programming a highly distributed system.
