The start of 2026 hasn’t been smooth sailing for Rigetti Computing (RGTI). The pure-play quantum contender recently pushed the “general availability” of its flagship 108-qubit Cepheus-1-108Q system to the end of the first quarter. The firm cited the need for additional testing and performance optimization, a move that sent ripples through a market already pricing in extreme growth potential for quantum technologies.
Cepheus-1-108Q is built from 12 9-qubit chiplets using Rigetti’s proprietary modular chip architecture, making it both the company’s highest-qubit system to date and the largest modular quantum computing system currently available in the industry.
