Quantinuum makes trapped-ion quantum computers, from the H1 and H2 systems to Helios, along with software such as InQuanto for computational chemistry. One of its two predecessors was Cambridge Quantum, and it keeps UK offices in Cambridge, London and Oxford. A July 2024 agreement gave the STFC Hartree Centre cloud and on-site access to H-Series machines, and in February 2024 Quantinuum was named lead of an actinide chemistry project under the Quantum Catalyst Fund. In September 2026 it ran its first InQuanto Summer School, for 30 researchers at Newnham College, Cambridge, with NQCC support.
Quantinuum, based in Cambridge, is a company. It is a partner in 4 UK projects, including QCi3, IQN and Quantum Catalyst Fund. Profiled here: Rajeeb Hazra (President and CEO).
