About

Quantinuum

Quantinuum is a quantum-computing company formed in 2021 through the combination of Honeywell Quantum Solutions and Cambridge Quantum. The business integrates hardware and software under one organization and maintains major operations in Broomfield, Colorado and Cambridge, United Kingdom. Its Broomfield address is 303 S Technology Court, Broomfield, Colorado 80021. The company develops trapped-ion quantum computers, software tools, algorithms and applications for fields including chemistry, materials science, machine learning and cybersecurity. Its cybersecurity work includes technology based on quantum-generated randomness and products intended to help organizations prepare for changes in cryptographic security as quantum computing develops. Quantinuum also provides cloud access and software environments for researchers and enterprise users working with its systems. Quantinuum differs from many quantum vendors because its organization includes both the physical computing systems and application software that runs on them. Honeywell contributed its quantum hardware operation, while Cambridge Quantum contributed software and application capabilities. The 2021 combination created the current entity, so no earlier predecessor date is used as Quantinuum's founding year.
