NEC Exits Its Quantum Hardware Program as Fujitsu Bets on Diamond Spin — September 8, 2026

NEC has quietly stepped back from building its own superconducting quantum computer, citing an ROI timeline too long to justify the capital — while cross-town rival Fujitsu, with TU Delft and QuTech, unveiled a diamond-spin prototype and a 2030/2035 logical-qubit roadmap. Plus: Singapore and Luxembourg pledge deeper quantum cooperation, and a University of Surrey team proposes a superfluid-helium qubit design.
