Disclosed defence money for quantum computing roughly doubled to tripled in 2026 against the 2023 to 2025 average, and all of the rise is announced money from two DARPA agreements. Obligated money on the federal register fell.

How Big Is the Quantum Defence Sector? The defence money for quantum technology that anyone can check runs to hundreds of millions of dollars a year, not billions. The Pentagon spent about $320 million on quantum research in FY2023, its latest year of actual spending.

Researchers Measure 58x Drop in Resistance of Cryo Inductors A key leap forward has been made in powering quantum computing; commercially available power inductors now deliver 25x to 58x when cooled to four Kelvin, the temperature near absolute zero.
15
High optical reflectivity and ultracoherent mechanical motion now coexist in a mirror thanks to newly created nanopillar metasurfaces that achieve 99.82% reflectivity alongside a Q⋅f product of two times ten to the power fourteen Hertz.

Researchers Find Optimization Boosts Don’t Guarantee Better Sampling Quantum annealers have been assessed primarily by their ability to find low-energy configurations; however, reaching a degenerate ground state and uniformly sampling it are distinct capabilities.
13
Quantum parameter estimation commonly assumes measured quantities exist as fixed values before and independent of measurement; it challenges that assumption, opening new avenues for describing estimations where the quantity may instead be a fluctuating quantum variable.

Researchers Bound Key Rates Independent of System Size Reliable predictions about complex quantum systems require knowing how quickly they reach stable states, a measure known as entropy decay.
