It has been nearly 5 years since the Computing Community Consortium (CCC) Workshop on Next Steps in Quantum Computing, and significant progress has been made in closing the gap between useful quantum algorithms and quantum hardware.  Yet much remains to be done, in particular in terms of mitigating errors and moving towards error-corrected machines.  As we begin to transition from the Noisy-Intermediate Scale Quantum (NISQ) era to a future of fault-tolerant machines, now is an opportune time to reconvene in a new CCC workshop to consider how to apply what we have learned thus far and what research needs to be done to realize computational advantage with quantum machines.  As with the previous workshop, this 2-day CCC workshop will bring together researchers in computer science (CS) and quantum information science, with a goal of identifying how CS expertise from classical computing can be adapted to accelerate the timeline to practical applications on quantum systems.

This workshop will focus on 5 topics:

1) Technologies and Architectures with a View Towards Scaling,

2) Applications and Algorithms,

3) Fault Tolerance and Error Mitigation,

4) Hybrid Quantum-Classical Systems: Architectures, Resource Management, and Security, and

5) Tools and Programming Languages.

We will frame our discussions of each of 5 topics with a short presentation on each topic, followed by a longer group discussion and breakout groups. Each breakout group will give a brief synopsis of their discussions when we regroup before proceeding to the next topic. Please see the agenda for more information.
