History

Historical Context

The National Quantum Initiative Act, passed on December 13 2018 and signed December 21, created a federal umbrella coordinating DOE, NSF and NIST to boost quantum research. Building on that framework, Congress introduced the Quantum Sandbox Act in May 2025 to accelerate near-term applications. The sustained public-private push now underpins Quantinuum’s Nasdaq IPO, where Honeywell retains 49.1% voting control.
