DOE advisers chart path to error-corrected quantum computer by 2028

Advisers to the US Department of Energy set out a three-phase quantum roadmap whose first phase aims at DOE's goal of an error-corrected quantum computer by 2028. Under Secretary Darío Gil announced it on 17 September 2026. Their illustrative 2028 range is about 50 to 100+ logical qubits.

BCG: quantum could eventually cut nearly 10% of global emissions

Quantum computing could eventually cut 3 to 7 gigatonnes of CO2-equivalent a year, the BCG Institute estimated on 17 September 2026. Its own footprint would be about 0.09 gigatonnes in 2040, against 1.31 for data centres at BCG's midpoint, and only 10% to 15% of the savings would arrive by 2040.
