The Computing Community Consortium (CCC) has released an updated report on quantum computing progress in the past five years, based on a workshop held in the spring 2023. While the CCC report doesnt break new ground its a good overview.

CCC posted a blog this week by Catherine Gill on the report that notes:

Quantum Computing is in the Noisy Intermediate Scale Quantum (NISQ) era currently, meaning that Quantum Computers are still prone to high error rates and are able to maintain few logical qubits. The work being done in Quantum Error Correction, however, is enabling Quantum Computing to transition towards a Fault-tolerant future. There has been remarkable progress in quantum computer hardware in the last five years, says Kenneth Brown, Professor of Engineering at Duke University, but challenges remain in terms of reducing errors and scaling systems. We thought it was critical to bring together experts in quantum computing, computer architecture, and systems engineering to plan for the next ten years.

The workshop and subsequent report focused on five areas:

The infographic list of qubit types below is a nice primer. Its necessarily incomplete as the number of qubit types seems to grow daily.

The report concludes Quantum computing is at a historic and pivotal time, with substantial engineering progress in the past 5 years and a transition to fault-tolerant systems in the next 5 years. Taking stock of what we have learned from NISQ systems, this report examined 5 key areas in which computer scientists have an important role in exploring.

Among the reports interesting findings is a recommendation to standardize QC benchmarking. We recommend exploring standardized benchmarking frameworks to identify a set of benchmarks which would enable us to evaluate quantum platforms, algorithms, and potential domain problems. For example, an end-to-end quantum machine learning benchmark would allow us to evaluate not only the general performance of a quantum device, but also the algorithms noise resilience and data sensitivity. More work on widely accepted benchmarks with input from other communities (computer scientists, machine-learning communities) may also lead to increased collaboration and interest from other domain experts.

(CCC is the NSF-created entity in 2007 The CCC operates as a programmatic committee of CRA under CRAs bylaws: its membership only slightly overlaps the CRAs Board of Directors; it has significant autonomy; and it has a great deal of synergistic mutual benefit with CRA. The CCC Council meets three times every calendar year, including at least one meeting in Washington, D.C., and has biweekly conference calls between these meetings. Also, the CCC leadership has biweekly conference calls with the leadership of NSFsDirectorate for Computer and Information Science and Engineering (CISE).)
