Rolling quantum dice with a superconducting qubit
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 $\ensuremath{\pi}$, $\ensuremath{\pi}/2$, and Hadamard gates---have been characterized with high accuracy. Here, we show how the Platonic …
