Query: High-fidelity gate operations for quantum computing beyond dephasing
  time limits   The implementation of quantum gates with fidelities that exceed the threshold
for reliable quantum computing requires robust gates whose performance is not
limited by the precision of the available control fields. The performance of
these gates also should not be affected by the noisy environment of the quantum
register. Here we use randomized benchmarking of quantum gate operations to
compare the performance of different families of gates that compensate errors
in the control field amplitudes and decouple the system from the environmental
noise. We obtain average fidelities of up to 99.8\%, which exceeds the
threshold value for some quantum error correction schemes as well as the
expected limit from the dephasing induced by the environment.
