- Communicate software feature roadmaps and resource needs between the control software team, adjacent stakeholders, and executive management
Our take
Quantum physics is a rapidly developing scientific field that promises great innovations within computing, with some working quantum computers already existing. However, such computers are extraordinarily expensive and complex to operate, making it difficult for startups to leverage the technology and apply it to commercial products.
Infleqtion, previously known as ColdQuanta, develops quantum computers, sensors, and networks, integrating them to form an ecosystem of cloud-hosted quantum infrastructure readied for commercialisation. This empowers businesses to leverage quantum computing without needing their own quantum computer, accelerating adoption of the tech.
While quantum computing has rapidly developed from proof-of-concept to practical applications in the last decade, it has yet to break into common use. By increasing accessibility to the current state of practical quantum technology, Infleqtion should be able to help disrupt industries across the board. Its research arm, which has retained the "ColdQuanta" identity, remains primed to bring new advances to the space, which will, in turn, be more quickly commercialised. Substantial funding raised through its IPO and SPAC merger with Churchill Capital X in 2026 means that Infleqtion is the first neutral atom quantum company to be publicly listed.
