Among quantum peers, D-Wave Quantum Inc (QBTS 7.21%) rose 7.21% to $27.52, and IONQ Inc (IONQ 4.28%) gained 4.45% to $75.14, with the group benefiting from rising interest in government-related quantum research.
Rigetti has been climbing since Sept. 18, when it announced a three-year, $5.8 million contract with the U.S. Air Force Research Laboratory to develop quantum networking in partnership with QphoX. The award builds on Rigetti's track record in federally backed quantum programs. For investors, the continued rally underscores how government contracts can validate the company's technology and provide funding support, though long-term value will depend on translating such deals into recurring revenue and broader commercial adoption.
