Rigetti Computing Inc. (RGTI) stock surged 5.12% in pre-market trading on Thursday, fueled by renewed investor optimism surrounding the future of quantum computing technology.

The rally was sparked by recent announcements from tech giants Microsoft and Nvidia, expressing their bullish views on the quantum computing sector and unveiling plans to drive further progress in the field.

On Tuesday, Microsoft announced its "Quantum Ready" program, aimed at helping businesses prepare for the quantum computing era. In a blog post, the tech giant stated that it anticipates the pace of quantum research and development to accelerate rapidly over the next 12 months, bringing meaningful applications closer to reality.
