  Spin qubits in quantum dots define an attractive platform for scalable
quantum information because of their compatibility with semiconductor
manufacturing, their long coherence times, and the ability to operate at
temperatures exceeding one Kelvin. Qubit logic can be implemented by pulsing
the exchange interaction or via driven rotations. Here, we show that these
approaches can be combined to execute a multitude of native two-qubit gates in
a single device, reducing the operation overhead to perform quantum algorithms.
We demonstrate, at a temperature above one Kelvin, single-qubit rotations
together with the two-qubit gates CROT, CPHASE and SWAP. Furthermore we realize
adiabatic, diabatic and composite sequences to optimize the qubit control
fidelity and the gate time. We find two-qubit gates that can be executed within
67 ns and by theoretically analyzing the experimental noise sources we predict
fidelities exceeding 99%. This promises fault-tolerant operation using quantum
hardware that can be embedded with classical electronics for quantum integrated
circuits.
