Universal Quantum Gate Set Approaching Fault-Tolerant Thresholds<? format?> with Superconducting Qubits
Physical review letters, 2012•APS
We use quantum process tomography to characterize a full universal set of all-microwave
gates on two superconducting single-frequency single-junction transmon qubits. All
extracted gate fidelities, including those for Clifford group generators, single-qubit π/4 and
π/8 rotations, and a two-qubit controlled-not, exceed 95%(98%), without (with) subtracting
state preparation and measurement errors. Furthermore, we introduce a process map
representation in the Pauli basis which is visually efficient and informative. This high-fidelity …

We use quantum process tomography to characterize a full universal set of all-microwave gates on two superconducting single-frequency single-junction transmon qubits. All extracted gate fidelities, including those for Clifford group generators, single-qubit and rotations, and a two-qubit controlled-not, exceed (), without (with) subtracting state preparation and measurement errors. Furthermore, we introduce a process map representation in the Pauli basis which is visually efficient and informative. This high-fidelity gate set serves as a critical building block towards scalable architectures of superconducting qubits for error correction schemes and pushes up on the known limits of quantum gate characterization.
