Randomized benchmarking of one-qubit and two-qubit operations in an ion-trap quantum computer — •Alexander Erhard, Roman Stricker, Daniel Nigg, Esteban Martinez, Philipp Schindler, and Rainer Blatt — Institute for Experimental Physics, University of Innsbruck, Austria

Randomized benchmarking provides a platform independent approach to characterize the performance of a quantum computer. Large scale quantum computers require quantum error correction, which can be realized using operations from the Clifford group. Hence we investigate the fidelity of our quantum computer using only operations from the Clifford group. We present randomized benchmarking experiments on a single qubit and on two qubits. We estimate the fidelity of a single Clifford gate from the decay of the fidelity with increasing gate sequence length.
