Spin qubits in quantum dots define an attractive platform for scalablequantum information because of their compatibility with semiconductormanufacturing, their long coherence times, and the ability to operate attemperatures exceeding one Kelvin. Qubit logic can be implemented by pulsingthe exchange interaction or via driven rotations. Here, we show that theseapproaches can be combined to execute a multitude of native two-qubit gates ina single device, reducing the operation overhead to perform quantum algorithms.We demonstrate, at a temperature above one Kelvin, single-qubit rotationstogether with the two-qubit gates CROT, CPHASE and SWAP. Furthermore we realizeadiabatic, diabatic and composite sequences to optimize the qubit controlfidelity and the gate time. We find two-qubit gates that can be executed within67 ns and by theoretically analyzing the experimental noise sources we predictfidelities exceeding 99%. This promises fault-tolerant operation using quantumhardware that can be embedded with classical electronics for quantum integratedcircuits.
