This activity requests $15.0M in FY2027, 2.5% of project MQB-01, up 3.5% on FY2026. The R-2A exhibit describes it across FY2026–FY2027, including what the FY2027 money is planned to buy.

What the FY2027 request buys

Verbatim from the R-2A exhibit for project MQB-01 of PE 0602025E. This is the budget justification's own description of work that has not happened yet — the one thing no other level of the budget carries.

FY2027 planned work

- Demonstrate initial components of heterogeneous quantum interconnects. - Demonstrate heterogeneous quantum circuit compilers on small reference circuits. - Develop preliminary heterogenous quantum computer architecture specifications.

FY2026 to FY2027 change

The FY 2027 increase reflects the shift from initial design and modeling activities to finalizing design and architecture of a heterogeneous quantum system.

Before the request year

FY2026: the year under way

Prior-year accomplishments and current-year plans from the same exhibit. Context for the FY2027 plan, not a series — an activity partitions its project exactly in the request year, but can under-cover it in earlier years.

FY2026 plans — current year

- Develop initial designs for components of heterogeneous quantum interconnects. - Develop initial modeling & simulation frameworks for partitioning quantum circuits in heterogeneous architecture. - Establish an independent verification and validation capable of performing technoeconomic analysis on heterogeneous quantum computer architecture.

Money

Three years, and no five-year plan

An R-2A activity publishes the prior year, the current year and the budget year. The FYDP outyears exist at project and program-element level and are deliberately absent here rather than inferred. Estimate types are colored and never summed into one figure.

This activity is 2.5% of project MQB-01's FY2027 request and 0.9% of PE 0602025E's. In the request year the activities under a project sum to it exactly; in the current year they under-cover it in about 9% of cases, so an activity's delta can legitimately exceed its parent's and the two must not be compared row to row.

Where this sits

Every R-2A line of this project, largest FY2027 request first. Linked where the activity has enough of its own narrative to carry a page; the rest are shown in full on the project page.
