Design and integration of single-qubit rotations and two-qubit gates in silicon above one Kelvin

Spin qubits are attractive for scalable quantum information, but integrating different classes of two-qubit logic has remained elusive. Here, the SWAP, CPHASE, and CNOT-class two-qubit gates are implemented in a silicon device operating even at temperatures above 1 K.
