GoKawiilNEC ends in-house quantum computing hardware development, researchers move to Fujitsu
According to a Diamond Online report, NEC quietly halted development of physical quantum computing machines at the end of March 2026, decades after pioneering superconducting qubit research in 1999. Several researchers from the program, including a key leader, have reportedly since joined Fujitsu, which continues investing heavily in the technology. NEC has not confirmed a full exit, stating it still evaluates practical applications and industrialization of quantum technologies with customers.
GoKawiil's interpretation of the reporting above, not reported fact.
NEC's early superconducting qubit work underpins hardware now used by Google and IBM, so its retreat signals how difficult it remains to turn foundational quantum research into commercially viable machines. The shift also reshapes Japan's competitive quantum landscape, consolidating hardware talent and momentum around Fujitsu rather than spreading efforts across multiple firms.
- NEC has stopped developing quantum computing hardware as of March 2026, per a Diamond Online report.
- Researchers from NEC's quantum team, including a key leader, have reportedly moved to Fujitsu.
- NEC says it will still explore practical quantum applications, but not build the machines itself.
