NEC Discontinues Superconducting Quantum Computer Development to Focus on Annealing and Classical Emulation

NEC Corporation has ended its research and development of superconducting quantum computers. The company will shift toward quantum-inspired annealing and classical emulation, concentrating on software and optimization services. Fujitsu remains the main Japanese corporate developer of superconducting quantum hardware.

OutlookPlausible

NEC could package its annealing and classical emulation capabilities into commercial optimization services for Japanese enterprises within the next two years.
