Workshop

As quantum computing starts to emerge as an interesting new computing paradigm, many challenges still need to be addressed, especially considering the needed advances in engineering to build, operate and integrate them. Interesting open topics include the interface between Quantum and Classical Compute systems, the role new architectures and control hardware has to play, and how to exploit developed and tested classical computer technology for the implementation or support of Quantum Computer system. 

Given the characteristics of quantum computers, hardware support will be critical in their design: quantum computers require dedicated and specific hardware devices for pulse generation and signal reading; they need to be built on top of new control processors; they require frequent calibration and tuning thus requiring some degree of adaptation and flexibility. For all these tasks, FPGAs offer themselves as an essential component for the support of Quantum Computing. While many individual efforts exist in this direction, so far no venue exists that brings the community together and enables the needed exchange of ideas and technologies on how to best utilize FPGAs for quantum computing.

This workshop addresses this gap and will mostly cover the following topics:

•   How FPGAs may be used to support quantum computer systems?

•   How FPGAs can be used in devices that produce the pulses to drive the commands to Qubits?

•   How FPGAs can be used in devices that read the signals produced from the quantum computer?

•   Which changes need to be done in the FPGA hardware technology to better help the integration and support of quantum computer systems?

•   Which changes need to be done in the FPGA development tool flow for supporting the special requirements of these new applications?

•   What new control structures, possible beyond von-Neumann are helpful in driving quantum computing control systems?
