US quantum computing company, Quantinuum, has announced what is being described as a significant step towards fault tolerant quantum computing.

Quantinuum's System Model H2 is said to be the highest performing quantum computer ever built and the launch of the H2 quantum processor, Powered by Honeywell, follows extensive pre-launch work with a variety of partners deemed essential to the controlled creation and manipulation of non-Abelian anyons. The precise control of non-Abelian anyons has been long held as the path to using topological qubits for a fault tolerant quantum computer.

Commenting Tony Uttley, President and COO of Quantinuum, said, "With our second-generation system, we are entering a new phase of quantum computing. H2 highlights the opportunity to achieve valuable outcomes that are only possible with a quantum computer. The development of the H2 processor is also a critical step in moving towards universal fault tolerant quantum computing." He added, "This demonstration is a beautiful proof point in the power of our H-Series hardware roadmap and reinforces our primary purpose which is to enable our customers to tackle problems that were previously beyond the reach of classical computers."

One of the first experiments conducted on H2 by scientists from Quantinuum, in collaboration with researchers from Harvard University and Caltech, demonstrated a new state of matter, a non-Abelian topologically ordered state. This is an area of expertise that has been pursued in "stealth mode" for some years within Quantinuum, with the core team based in Munich and led by Dr. Henrik Dreyer.

Due to the differentiating features and precision control of the H2 processor, the topological state (that is essentially a qubit with limited gate capacity) was created in such a way where its properties could be precisely controlled in real-time, demonstrating the creation, braiding and annihilation (measurement) of non-Abelian anyons.
