NEC Reportedly Exits Quantum Computing Hardware Development, Shifts Focus to Applications

NEC's Shift from Hardware Development

According to a Diamond Online report, NEC has quietly discontinued its quantum computing hardware development as of March 2026. This marks a significant change for a company that was among the earliest developers in the quantum computing field, having researched superconducting quantum computing since its inception.

Historical Contributions and Current Strategy

NEC researchers demonstrated the world's first superconducting solid-state qubit in 1999, a foundational technology now used by companies like Google and IBM. Despite this historical role, NEC has apparently concluded that developing commercial quantum computing hardware would take too long to generate sufficient returns. The company will now focus on evaluating practical applications, industrialization of quantum technologies, and conducting proof-of-concept projects with customers.

Researcher Exodus to Fujitsu

Following NEC's decision, many researchers involved in its quantum computing program, including a key research leader, have reportedly moved to rival Fujitsu. Fujitsu continues to invest heavily in superconducting quantum computing hardware, having launched a 256-qubit machine with Riken last year and aiming for a 1,000-qubit machine in 2026. The influx of experienced NEC researchers could strengthen Fujitsu's existing operations.

Company Stance

NEC has not formally characterized this move as a withdrawal from quantum computing. In response to Diamond, the company declined to comment on exiting hardware development, stating it continues to evaluate practical applications and industrialization. This suggests NEC is exiting the costly and risky development of physical quantum computers while remaining involved in quantum technology through software, algorithms, and customer projects.
