Rolling quantum dice with a superconducting qubit
One of the key challenges in quantum information is coherently manipulating
the quantum state. However, it is an outstanding question whether control can
be realized with low error. Only gates from the Clifford group -- containing
, , and Hadamard gates -- have been characterized with high
accuracy. Here, we show how the Platonic solids enable implementing and
characterizing larger gate sets. We find that all gates can be implemented with
low error. The results fundamentally imply arbitrary manipulation of the
quantum state can be realized with high precision, providing new practical
possibilities for designing efficient quantum algorithms.Comment: 8 pages, 4 figures, including supplementary materia
