Quantinuum's Chief Scientist, Harry Buhrman, argues that high physical fidelity in quantum gates is more critical than raw gate speed for achieving fault-tolerant quantum computing. He highlights Quantinuum's trapped-ion architecture as superior to superconducting platforms due to its low error rates, which significantly reduce the resources needed for quantum error correction. While trapped-ion systems currently have slower gate speeds, Quantinuum aims to overcome this limitation by 2029 to make its Apollo system commercially competitive.
