About Quantinuum
Quantinuum builds trapped-ion quantum computers, including the H-series and the newer Helios system, in which atomic ions serve as qubits. It also develops quantum software and offers cloud access to its hardware. The company was formed in 2021 by combining Honeywell Quantum Solutions, the hardware unit, with Cambridge Quantum, the software firm, and Honeywell was the majority shareholder at formation. Quantinuum has operations in Broomfield, Colorado and Cambridge, United Kingdom.

What Quantinuum works on
Quantum Computing
A quantum computer is a machine that uses the rules of quantum physics to process information. Its basic unit is the qubit. A classical bit is either 0 or 1. A qubit can be in a superposition, a state that combines both, and its measured result is probabilistic.
