Early commercialmomentum 676,373 papers a year (+16%)$3.2B raised in 12 months26 companies
Computers that use qubits, which can hold superpositions of 0 and 1, to solve some problems ordinary computers cannot.
Why early commercial: Vendors sell systems and cloud access, and Quantinuum closed a $1.68 billion IPO on Nasdaq in June 2026. Jun 5, 2026This week: Modular quantum computing took shape with l-couplers, while MIT News reported on quantum computing powering up for a pivotal moment.
