The Department of Energy's formal RFI is a procurement signal: "fault tolerant" is a defined technical bar today's quantum hardware hasn't yet met.
The Department of Energy has put a 2028 clock on a defined federal ask: a fault-tolerant quantum computer, hardware that can run long calculations while actively correcting the random errors today's quantum machines are swamped by. The ask is now visible on the federal procurement record. A Request for Information on SAM.gov and a competition track on grants.gov (the Quantum Genesis Q Competition) translate the press release into real solicitation artifacts.
"Fault-tolerant" is the load-bearing phrase. Without it, qubits stay in the noisy regime. The 2028 target sets a defined technical bar, and it is a procurement milestone, not a vendor demo date.
Programmatic context sits in the DOE Office of Science ASCR program documents and an OSTI blueprint on quantum supercomputing. Trade press has covered the RFI at The Register and Quantum Computing Report.
The clock is short for this category of hardware. What remains unspecified in the public record is the funding scale, the precise 2028 milestone definition, and the named performers the competition will pick.
