Abstract

This paper demonstrates the successful integration of single-qubit rotations and various two-qubit gates (CROT, CPHASE, and SWAP) in a silicon double quantum dot device, operating above one Kelvin. The researchers overcome challenges related to the finite Zeeman energy difference between qubits by employing adiabatic and diabatic composite pulse sequences, achieving gate times under 100 ns and predicted fidelities exceeding 99%. This advancement significantly reduces operational overhead for quantum algorithms and paves the way for scalable quantum integrated circuits.
